Abstract

In a process and apparatus for binding books, upper (forward) portions of bookblocks in a vertical position with backs down are gripped by clamps on a conveyor for transporting the bookblocks through successive operating stations. At one operating station a rotating element dipping in a bath of adhesive applies adhesive in transverse strips to backs of bookblocks. At another operating station rollers apply adhesive to lower (rear) portions of first and last pages of the bookblocks. As front and back covers connected by a back are transported, inside up, along a path merging with the path along which said bookblocks are transported, adhesive is applied by rollers or spray heads to outer (forward) portions of the front and back covers. The covers are brought under respective bookblocks and lower (rear) portions of the bookblocks together with the covers are gripped between opposed pressing bars. As the bookblock with the cover thereon is further advanced in a guide channel, the clamp is removed and the book passes between pairs of opposed rollers which engage lower (rear) portions. Finally the books are pressed between opposed pressure plates before being discharged to a delivery system or to storage.

Description

The invention relates to a method for binding a book, in which a continuous cover with covers is placed around a book block and glued to parts of the same. The invention further relates to an apparatus for performing this method.

There are various methods for binding books, which depend on the bookbinding design of the book. The cover and spine of the brochure consist of a uniform cardboard box that is only glued to the back of the book block. The method according to the invention is not intended for such brochures. All other types of binding have a book block which is to be connected to a higher-quality cover or cover part in such a way that there is a better and more permanent connection between the cover and the book block. In the case of the thread-bound book block, part of the back fumigation projects over the back and so far it has been carried out in a conventional manner with conventional hanging machines after attachment and full-surface gluing of the intent to hang the book cover. The same procedure is followed for the adhesive-bound book block with gassing and hanging in a rigid blanket. The manufacturing effort is relatively large and it is not possible to manufacture very large quantities per hour. This largely depends on the fact that the entire surface of the attachment has to be glued and glued to the lid. Also in other laminating processes, for example in the production of children's books, in which the cover and the spine are to be fastened on the inner book part or book block, which is usually made up of laminated cardboard boxes, suitable connecting processes are required. There is also a need for a high-quality book with a semi-rigid cover and an attachment with the aid of an attachment in order to use at least the continuous attachment, if not additionally also the gauze strip extending to the cover, to increase the durability in the joint. Even with this type of book called "semi-hard cover", one has so far had to work with the usual attachment and hanging machines that only allow a limited processing speed. For all of these book binding processes, there is a need to increase the speed and to guarantee high-quality integration with simple machines.

The usual methods mentioned above are described in many different publications in a wide variety of variants. The constructions according to the following documents come closest to the subject of the application.

From GB-A-613 791 it is known to let the first and last sheets of the book block pass horizontally between glue rollers with horizontal axes and immediately afterwards to slide them freely into an open envelope between the dry covers and then to cover them with the help of on the outside of the Rolling the cover, pressing from above and below effective rollers, whereby the joint area in the roller must be cut out accordingly. Such a device can only be operated at low speed and it is difficult to achieve precise alignment. Different pressure rollers are also required for different formats and a corresponding longitudinal alignment of the device parts is required. The device is complex.

In the device according to DE-A-2 264 336 (p. 40 ff.), Glue is applied to the inner surfaces of the covers or to the front and back sides of the books, that is to say the first and last sheet of the book block, for a long time before being connected with suitable ones Means applied and allowed to dry before the books reach the wrapping and mounting device (more correctly ("hanging device"). Using adhesives that can be reactivated by heat or by a solvent. After the book block and cover have been put together, the covers are laid flat and the standing book block reactivates the glue on the gluing surface by heat or sprayed on solvent, so that when the lid is swung up, the full-surface adhesive binding can be carried out by means of the glue provided on one side of the lamination surface related problems can be realized.

DE-A-12 257 614 discloses a device for applying glue with the aid of glue rollers to an area of the book block adjacent to the spine. Measures for gluing further areas are not apparent. This device is not suitable for the entire process. It is only a common part of gluing devices in bookbinding machines.

From GB-A-1 262 018 and DE-B-2106 496 it is known to allow a portion of the book block adjacent to the spine to protrude downwards out of the conveyor belts by a small amount in a system with the book blocks supported by laterally adjacent conveyor belts and First glue the spine from below and then glue the side of the narrow section of the first and last sheet of the book block adjacent to the spine with side glue and then feed the continuous cover from below and press a lying full cover with its central area against the back. The book block then leaves the side conveyor and holding belts and is in his The upper area is taken over by a clamp that is able to move back and forth and horizontally feeds the book block with loosely attached and open covers into a residual surface gluing station. There, edge areas of the cover sheet near the back can be pressed. In the remaining surface gluing station, the lid must be inserted under the glue rollers and glue containers so that small glue rollers can reach the remaining surfaces of the first and last sheets when they are inserted vertically between the glue rollers, which are spaced apart and have horizontal axes. The remaining surface gluing rollers are then brought up to the book block from both sides. The clip is opened and the book block goes down between the glue rollers while its cover folds. The remaining surfaces of the first and last sheets are glued and the non-glued inner surfaces of the covers are placed on the first and last sheets of the book block when falling between pressure rollers, while not being held by a clamp.

Such a device is complex in construction and the procedure is unsafe and can only be handled at low speed, because the alignment and the attitude of the parts to be joined are unsatisfactorily solved. In the case of free-falling and free-rolling books, the book block and cover can move among themselves. The device is also only suitable for soft envelopes that are also to be glued continuously to the back. The device and procedure are not suitable for quickly attaching a wide variety of book blocks to different blankets, especially not if a high-quality book with perfect alignment of the book block and cover is to be achieved.

The technology according to GB-A-1-262 018 and DE-B-2106496 divides the areas to be glued into a region close to the back and into a remaining area in different stations. However, it is glued on the same surface, namely on the book block and not on the ceiling. The proposed technological measures do not appear to be reasonable.

From WO-A-81/03644 a bookbinding method is known, in which, after cutting the back and attaching a crepe strip encompassing the back and the edge area of the first and last sheet of a book block, a soft additional inner cover with the aid of glue strips in the area near the back is stuck to the crepe. Then apply hot glue on the back of the soft inner auxiliary blanket and in the edge areas. Cold glue is only applied to the entire surface of the cover on a continuous ceiling with covers and back. Then the soft back of the soft additional inner auxiliary blanket is glued to the back area of the blanket. The cover surfaces with their full-surface gluing are glued to the outer surface of the auxiliary ceiling. Some glue gets from the back onto the side surface parts of the back that extend to the joint area. This procedure requires a high manufacturing effort because an additional inner cover is required, so that first a book to be produced in the manner of a 'paper back' must be provided, which is then hung in a fixed cover.

Also in the second embodiment according to WO-A-81/03644, a soft inner blanket is used, which consists of two attachments and a backing strip, which are initially to be manufactured separately or fastened one after the other and which are then glued to the inner surfaces of the covers and below Glueing the back of the auxiliary blanket or the back strip of the auxiliary blanket formed with the attachments are connected.

For both embodiments applies that the fully glued lid can not be processed in manufacturing processes that should not work manually, but with high speed, because when the glued lid is folded up, the holding and guiding means that are necessary to hold the block and to transport and possibly to guide the lid, from which the glue of the lid would be smeared. There is also no technology in the font that shows how this book should actually be made.

The invention is based on the object of specifying a method and a device suitable therefor, by means of which the outermost sheet can be laminated onto a cover or the like at high speed in continuous processes in which the block can be held with clamps. The main idea of the method according to the invention is characterized in that for the purpose of laminating the outermost sheets of the book block with the covers, the first and last sheets are provided with glue applications separately in the remaining front section of their surfaces and in each case in a partial area of the laminating surface adjacent to the back Areas are then joined together. The invention therefore goes from the usual way of coating the entire surface during lamination and divides the lamination surface into two regions, one surface region being glued to one lamination part and the other surface region being glued to the other lamination part. This allows holding and guiding means on the part not to be glued during manufacture Allow to attack and so with great speed the well-held parts of the book, namely the book block on the one hand and the cover with the back on the other, provided with the required glue in various ways and then put it together.

While in the proposal according to GB-A-1 262 018 and DE-B-2 106 496 only a small edge area close to the back was coated with glue and then in a second step the remaining surface parts of the same first and last sheet were coated with glue in the invention, preferably a larger area close to the back, in particular an area of approximately 50 to 60 mm, is provided with glue on the book block. The remaining part of the lamination surface is provided with glue on the corresponding remaining area of the respective cover. For the purpose of gluing the other subareas which are not glued to the book block or to the first or last sheet, the surfaces of the lids corresponding to these subareas are provided with glue applications which match the dimensions and are then preferably pressed onto the book block in a fresh, adhesive state. In the proposal according to GB-A-1 262 018 and DE-B-2 106 496 it is not recognized that there is no risk of smearing edge areas and / or device parts in a continuous operation with gluing in the cover if the glue orders are in suitable surface areas exactly to the intent or the like.

If you do not want to use special process steps and device parts and measures, you will usually use elastic lids, as these can be bent when they are joined together without suffering any damage. However, stiff lids can also be processed. The basic type of procedure does not depend on how the spine is designed and what type of binding is chosen for the spine, whether it is stitched or bound or whether the cover part of the spine remains loose or is firmly attached to the spine of the book block. It is also irrelevant whether a strip of gauze is used, although this is usually advisable. Also, a folded attachment does not necessarily have to be used, but the outermost sheets of the book block can also be laminated directly onto the covers, as is the case, for example, with the blocks of children's books formed from folded and laminated cardboard boxes or also simple brochures that However, should be provided with a stiffer, laminated cover and where, if necessary, part of the gauze strip can be glued in between the foremost single sheet and the cover, so that a better strength in the joint is achieved than in the simple brochure, on the other hand not the manufacturing effort for a folded header needs to be operated. It is known from other gluing techniques in the field of book binding, especially for back gluing, to apply glue in some areas. However, this is usually done for the purpose of processing with different glues. The surfaces to be glued are also divided into different surface sections. However, these known techniques have not been able to give any suggestion to divide the entire lamination area into different glue areas and, if necessary, to apply the glue with different techniques and then to connect the lamination areas, since they do not deal with the question of attack by transport and holding means in the Area of the surfaces to be glued during production, because the methods and devices have so far been designed so that all surfaces to be glued are not held simultaneously during the gluing process and afterwards. By dividing the laminating area into different glue areas, it is now possible to hold both parts to be laminated well and securely and to bring them together very well aligned, thereby significantly increasing the processing speed despite the high quality.

The glue application on the two partial surfaces can be carried out in various ways known for the glue application at other locations, for example with roller gluing units or with nozzle gluing units, whereby one glue strip can also be applied with a roller gluing unit and the other with a nozzle gluing unit. The book block is expediently held in brackets of an at least partially automatic machine during most of the lamination process, with a portion corresponding to the part adjacent to the spine protruding beyond the edge of the bracket. In this protruding area, the glue application can then be carried out cheaply with glue rollers.

In this case, it is expedient if the rear regions that protrude from the holding device, in particular clips, that are adjacent to the back are sufficiently large and preferably have a width of approximately 50 to 60 mm. With previous glue streaks near the back, which were made for other purposes, these were only narrow because one wanted to glue only one attachment, glue a paper-back envelope also over the back to a groove that preferred an articulated folding or to glue a small part near the back then in a later station on the same sheet to paint the entire large remaining area. The invention, on the other hand, is about covering a large area of about 50 to 60 mm, which is provided as a laminating surface for a good connection between the first and last sheet and lid, in such a way that it offers good laminating conditions. The remaining areas are provided with appropriate glue applications on the lids.

When hanging up so far, the first or last sheet, usually the header, was coated over the entire surface, because in many books the cover overlaps slightly over the book block on all sides and because when the corresponding areas of the cover are glued over the entire surface, narrow glued edge areas stick over survive the book block and would not be covered by the resolution. In the devices and procedures described in detail below, the glue is now applied to the ceiling in accordance with the cycle of the machine and the length of the required glue application. Conventional clock controls for nozzle gluing units or the cliché rollers that are common in printing technology can be used.

Since you will usually use a glue for lamination that takes a long time to set, you can also apply a small amount of glue with a small surface area for fast processing, which sets quickly and in places that fix the envelope well on Enable book block. For example, glue spots or strips of glue can be applied to the back just before the cover is pressed in, i.e. before this glue has hardened. Hot melt adhesives or other very quickly setting glues are particularly suitable for this. Then you can provide the remaining glue areas with slowly setting glues and still process them quickly in one go due to the immediate fixation of the cover and book block. Glue points or strips for fixing amounts can also be applied to the book block and / or the cover in the corner areas between the back and the first and last sheets or covers during processing. This type of fixation is particularly suitable for hard ceilings.

Depending on the design of the machine, the cover can be fed to the book block, for example placed on a correspondingly coated book block from above. For a particularly fast and inexpensive processing, a further embodiment of the invention provides that the spine and cover lie flat in a book block which is moved in a horizontal plane, with its leaves standing vertically, the spine of which is at the bottom, and the spine or parts of the cover shortly after the attachment of the quick-setting glue points or strips of glue, are pressed in such a way that the cover surface is then pressed on in the area adjacent to the spine and protruding from the clamp with rollers, press disks or press swords that press on the cover from the outside, and that the book block then the Leaves clip and is pressed in at least one surface press at least on the entire cover sides, but preferably also in the back with the back glued. The surface pressure can be divided into a roller pressure and a flat plate pressure.

The application and pressing can be done in places with sliding guide means, such as sliding strips or sliding surfaces, however, pressing on with rollers or fixed pressure elements is useful at times.

The invention can be implemented very easily on conventional bookbinding machines by designing such that the book block is held at a large distance from the spine and that corresponding roller and / or nozzle gluing units along the orbit of the book blocks at suitable locations and in a suitable manner appropriate clock control can be attached. The effort for this is much less than for conventional front-mounted adhesive and hanging machines.

Some parts of the device and arrangements as well as stations arranged one after the other on corresponding machines with traction means and holding devices can be designed in a manner similar to that of the machine treated in GB-A-1 262 496 and DE-B-2 106 496 with side glue lines close to the back. However, many device parts of this arrangement are not suitable for high-quality gluing and hanging, especially in high-quality, relatively rigid or rigid ceilings.

A device for carrying out the method for integrating a book according to the method features described above is equipped on the one hand with a base frame with guide and drive means, a rotating traction device with attached clips for the book blocks, and a device for the book blocks with a portion corresponding to the area to be glued To supply the excess of the clips and to allow them to be gripped by the clips, a device (side gluing station) for applying glue to the portion of the laminating surface of the foremost and the last sheet of the book block projecting beyond the clip and backing and at least one device for pressing the covers . It is characterized above all by a device for applying the glue to the front parts of the cover, a device that becomes effective after pressing on the partial areas of the cover adjacent to the back, to release the book block, a device for applying the remaining glued to the cover and surfaces to be concealed.

These minimal features and construction details or stations are naturally provided with the usual additional equipment familiar to the person skilled in the art, in order to achieve a fully functional machine shape. If you want to improve the alignment between the book block and the cover and to increase the working speed, it is expedient that a device for attaching a quickly setting glue point or strip of glue to the book block and / or spine and / or cover parts (strip glue station) on the device is also on the device of the book block is provided in front of the device for the aligned feeding of envelopes.

Exemplary embodiments of the invention in terms of the method and the device are explained in more detail below with reference to the drawings, which are essentially designed schematically.

1 shows a top view of an example of a device 20 for preprocessing books in the method according to the invention.

Individual stations are shown schematically in FIGS. 2 to 11.

The device 20 has two drive and deflection wheels 21.1 and 21.2, the axes 21.3 and 21.4 of which are indicated by dash-dotted lines. The drive or deflection wheels rotate around these vertical axes. They are driven in the usual way and carry traction means, such as chains, to which the brackets 22 are attached. These are two mutually parallel flat plates 22.1 and 22.2 with a stop and feed pin 22.3, the guidance and attachment of which are not shown in detail in FIGS. 2, 3, 8 and 9 because they are known and customary. The book blocks 25 are fed to the brackets 22 via a feed device 23 with storage and or insertion channels and drive means of a known type and are received in the area 24 by the brackets 22 as shown in FIGS. 8 is shown, namely that from the book block 25, the portion 27 adjacent to the back 26 protrudes downward from the bracket 22, namely by a width of, for example, 5 to 6 cm. The running direction of the bracket 22 is indicated at 28. After running in and holding in the respective clamp 22 in the area 24, the book blocks 25 first reach the strip gluing station 30, then the side gluing station 31, which are shown in more detail in FIGS. 2 to 5. Then the books turn around the drive wheel 21.2 to get into the return of the web. There they arrive at the cover arranging station 32 and on to the cover and page press station 33. A certain distance afterwards the book blocks 25 are released from the respective clamp 2 and arrive in a conveying channel 34 to the roller press station 35, which is shown in more detail in FIG Bottom press station 36, then to the top press station 37 and finally to the tray 38. Such a run is common on machines of this type, but the aforementioned special stations have not been arranged in this way. A schematically illustrated envelope feeder 40 is provided for feeding the envelope. One follows him Umschlagbeleimstation 41. There is provided its own conveyor system, not shown. The envelope feeder is explained in more detail with reference to FIGS. 6 to 8. It is arranged and designed such that the flat covers are guided under the cover station 32.

The strip gluing station 30, as illustrated in FIGS. 2 and 3, has a glue trough 50 in which there is glue 51 with a surface 51.1. Two strip glue arms 52 are rotatably arranged about the axes 52.1 at a distance from one another and are mounted above the glue surface 51.1 such that the strip glue dispenser 52.3 is immersed in the glue 51 during its rotational movement in the direction of the arrows 53, which corresponds to the running direction 28, and with the aid of its outer surface 52.4 each apply a narrow strip of glue 51.2 at a distance from the end or exactly at the end of the book block to the back 26 of the book block 25, as illustrated in FIGS. 2 and 3. Usual holding means for the tub and the bearings are not shown for the sake of simplicity, because it essentially depends on the scheme of the processing method. The glue 51 is a very fast setting glue, for example a hot melt adhesive. Then the tub also has suitable heating devices, which are also not shown. The glue 51 must be set in its setting time in such a way that the glue strips 51.2 on the back 26 on the way from the strip glue station 30 to the handling device do not yet set, taking into account the running speed, but remain sufficiently adhesive, but that they soon achieve sufficient strength becomes.

The strip glue station 30 is followed by the side glue station 31 in the direction of the circulation. This also has a glue pan 55 with glue 56. Two glue transport disks 58 revolving around a horizontal axis 57 are constantly immersed in the glue 56. These again touch the actual side glue rollers 59, which are designed as net rollers and provide the areas 27 of the two outer sheets 25.1 and 25.2 adjacent to the back 26 with the glue application 56.1, as is indicated schematically in FIG. 4 by the diamond pattern. The glue application can be dosed very well according to the needs. The book block 25 is pushed between the side glue rollers 59 with a full touch. The running directions are shown in the drawings 4 and 5 by arrows.

The envelope feeder 40 is not shown in detail. It is expedient to use a roller feeder pulling down from the stack or a feeder with horizontal movement. Such investors are known. This envelope feeder places the respective envelope 60, which comprises the two lids 60.1 and 60.2 and the back part 60.3 as a one-piece box or the like, on a horizontal guideway 40.1, the adjustable contact angles 40.2 and 40.3 of which are shown in FIG. 6. With the aid of traction means 61, two feed fingers 62 are advanced, which take the envelope 60 with them and guide them through the envelope gluing station 41.

FIG. 6 illustrates one possibility of a cover gluing station 41. Here separate gluing units 65 are provided for each front part area 60.5 and 60.6. A net glue roller 65.1, 65.2 running in the running direction, a transfer roller 65.3 and 65.4 as well as a glue removal roller 65.5 and 65.6 are provided. The glue pick rollers 65.5 and 65.6 dip into a glue pan 65.7 and 65.8, respectively, and take the glue from them, which they transfer over the transfer rollers 65.3; 65.4 to the net glue rollers 65.1 and 65.2. These in turn roll on the inner surfaces of the covers 60.1; 60.2 in the front part area 60.5 and 60.6, respectively, and there produce glue applications 56.3 and 56.4, as indicated in FIG. 6 by the spread diamond networks. When the envelope 60 is pushed forward with the aid of the feed fingers 62, the envelope is provided with the glue application over the entire length in the front part area 60.5 or 60.6. A section 60.7 and 60.8 remains on each side up to the back 60.3. This fits to the partial area 27 on the respective outer sheet of the book block 25.

FIG. 7 shows an alternative or variant for the design of the envelope gluing station 41. The same elements are provided with the same reference numerals as in FIG. 6. Here too, the envelope 60 is advanced by the feed fingers 62. Instead of the roller gluing units 65, however, glue nozzles 70.1 and 70.2 are arranged transversely to the running direction 28 in the width of the front part regions 60.5 and 60.6, respectively. It is known glue nozzles, the supply lines 70.3 and 70.4 are indicated. Other devices for supplying these glue nozzles with glue in accordance with the cycle of the machine and precisely for the time which corresponds to the length of the glue application are not shown. They are designed using conventional technology and have an appropriate clock control. They are also equipped with appropriate setting devices for dosing the glue application. Here the glue is applied 56.5; 56.6 not in the form of a network, but in the form of strips, as can be clearly seen in FIG. 7.

FIG. 8 illustrates the process in the envelope arranging station 32. As can be seen in FIG. 1, this is assigned to the envelope feeder in such a way that the feed fingers 62 are exactly aligned with the stop and feed pin 22.3 or are offset by the corresponding overhang , so that now the cover 60 fits exactly to the book block. By means of corresponding relative movements of the cover and book block to one another, in particular by slightly lifting the back part 60.3, this is glued with the adhesive strips 51.2 the spine of the book block 26 is connected so that the aligned cover 60 now adheres firmly to the book block 25. The quickly setting glue can now harden, while the glue areas that are slowly applied to the laminating surfaces and represented by the nets remain soft and adhesive. Now the clamp 22 takes the book block 25 together with the cover 60 and arrives at the cover and page press station 33, which is shown in more detail in FIG. 9. As can be seen, the at least somewhat elastic covers 60.1 and 60.2 have been raised in the outer region, which can easily be done by running the horizontal guideways 40.1 to 40.3 upwards. In order to create a clean back with well-formed corners and, above all in the joint area, to press the non-glued cover with the innermost part of its partial areas 60.7 and 60.8 onto the glued partial surfaces 27 of the book block 25, horizontally movable ones with their front edges 72.3 and 72.4 are from the outside side press swords 72.1 and 72.2 pressing against the covers 60.1 and 60.2 are provided, which press on the covers in a correspondingly solid manner with suitable feed means in the direction of arrows 73.1 and 73.2 and then move away again in the opposite direction. This can be achieved in a moving movement by means of a corresponding crank design. At the same time, a back pressure plate 74 presses upward from below according to arrow 75 and presses the back off. The book block 25 is - as can be seen - held in bracket 22. The back pressure plate 74 is then quickly withdrawn in the opposite direction. During the further course of the book blocks 25 with the spine and cover now pressed on, the outer cover parts are raised further in suitable guideways, but in such a way that they do not touch the clamps 22 with the adhesive. When the respective book has arrived above the conveying channel 34, the clamp 22 is opened and the book falls on its back into the conveying channel 34 and is pushed forward there by suitable feed means, initially possibly the stop and feed pin 22.3, but then by one other funding, because now the respective bracket 22 turns around the deflection and drive wheel 21.1 and enters the other path to pick up a new book block. The feed device of the conveying channel 34 continues to advance the book. At the same time, the conveying channel tapers, so that the still adhesive covers rise and align with the outermost pages of the book block. Now the book arrives in the roller press station 35, which - as can be seen in FIGS. 1 and 10 - has four pressure rollers 77, which have vertical axes 78 and whose vertical peripheral surfaces 77.5 carry out the pressing of the cover in a larger area than the pressure swords 72 to press the next area of the lid cleanly and without wrinkles and to ensure a good connection between the lid and the outer sheet, if necessary by pressing in the protruding part of the back gauze or the hem strip. Instead of the rollers, laterally effective, correspondingly high pressure plates can be provided, which can run along. If you work in time, you can also stop here.

The roller press station 35 is followed by at least one plate press station, but preferably two plate press stations, as shown in FIG. 1. 11 illustrates only the top press station 37 of the plate press stations 36 and 37. The bottom press station can be constructed in the same way, except that it acts on another part of the book. The book is fed to this press station through the feed system with the press plates open. Either the book is stopped or the press plates are carried along. The press plates 79.1 and 79.2 are fastened on press dies 79.3 and 79.4, which can be moved in the direction of the arrows 80 and press a book in a known manner, but here for the purpose the lid and outermost sheets glued to different parts of the laminating surfaces are finally and firmly joined together glue.

After the press plates 79 have been opened, the finished book is transported to the tray 38 in the conveying channel 34 with the aid of the transport mechanism and can be stacked there or fed to other devices, intermediate storage, packaging or the like. Possibly. the book can also be subjected to the three-page cut if this has not already been done. It depends on the type of book and the type of binding.

The implementation of the invention in the method or a device can be connected to differently designed machines that perform other operations on binding the book. That depends on the respective binding process. For example, prior to the application of the glue strips 56.1 to the back, the back can be processed by a milling cutter and by back gluing and, if necessary, a gauze can be applied. The book block 25 can also be provided with a folded attachment before stapling. At the infeed station, block feeders can be provided for thread-stitched or adhesive-bound books with and without fumigation. The attachment station can be provided in the area of the inlet. Other stations customary in book binding can also be used with the stations for realizing the invention on one and the same perfect binding machine or in one and the same production line. The new design now makes it possible to produce a high-quality book at the speeds possible for the collating machine or other perfect binding.

12 to 22 schematically illustrate some types of books and processing steps on them, but only partial working steps are shown to illustrate the essential distinguishing features of individual books bound according to the invention. The presentation is not intended to be exhaustive, but to point out some important points of view throughout the process.

Fig. 12 illustrates a book block 25.4, which consists of individual layers 25.5, which are folded at 25.6. This book block 25.4 is to be bound by adhesive. 13 illustrates how the book block held by the clamp 22 is milled off in the spine 26 with the aid of a milling cutter 85 and then has the appearance shown in FIG. 14 with sheets open on all four edges, the spine 26 of which is schematically shown in FIG 15 shown back glue roller 86 of a gluing unit is guided. When this process has ended and a gauze is possibly placed on it, which was not shown here, however, the strip gluing is carried out in a strip gluing station 30 with the aid of the strip glue dispenser 52.3 using a quickly setting glue. (Fig. 16) Then the two partial areas 27 or 56.1 and 60.5 or 60.6 are glued in the manner described above, the end result of which is shown again schematically in FIG. 17. Then the other operations described above follow.

18 to 21 illustrate a book block 25.8 which is provided with a gauze strip or fold strip 90 in the back, the projecting edge regions 90.1 of which will be arranged between the outermost sheets and the cover 60. Only the strip gluing in FIG. 19 and the roller gluing of the block and the protruding strip 90.1 in FIG. 20 are shown. Here you can see how the roller glue is applied over the edge areas 90.1 of the fold strips 90. FIG. 21 illustrates how the folded-over and glue-coated envelope 60 shortly before pressing also encompasses the glued edge areas 90.1 of the backing gauze or the hem strip 90 and will cover it after the final pressing.

22 illustrates in the last phase of the pressing a book block 25.9 which is stitched and whose layers 25.5 are consequently still folded in the back, which is indicated by the curves 25.6. The folded cover 60 covers this binding produced in the usual thread stitching and thus also creates a quick hanging for the thread stitched book in a blanket suitable for this processing operation.
