Description

TECHNICAL AREA

The invention relates to the field of further processing of precursors (especially of printed products as part of the print finishing). It relates to a method and an apparatus for producing collections of printed products.

The invention further relates to a device for carrying out the method.

BACKGROUND OF THE INVENTION

For a long time activities have been known under the heading "direct mailing" in which advertising leaflets, brochures, flyers, printed sheets, samples and the like, as they were otherwise often (advertising) attached as leaflets of a newspaper or magazine, can be collected by multiple advertisers to make a variety of collections, each containing a print product from a variety of advertisers and delivered in the form of a small stack to the recipient (eg households) and distributed.

In order to better handle the individual stack-like collections of printed products during transport and distribution, it is advantageous to take measures to hold together the individual stacks.

Methods and apparatus are known in the art to hold stacked printed products or related products together by wrapping with other cohesive elements.

DE 4 131 277 C1 shows a method and a device suitable for this, with which a packaged goods can be combined with a special packaging blank. Shown is a device in which a packaged product passes from a first feed device to a second feed device. The second feed device has a lower belt, which is guided on one side over a roller. With a pressure device, which has a pinch roller and a guide element, an articulation of the package blank is to be effected on the roller to lead the package blank in different ways to the packaged goods. The packaging blank is handled in this process to the packaged goods, the apex area of the turnaround is not specially processed. Therefore, in order to prevent the folded package blank from re-unfolding due to internal stress, only package blank having certain properties (e.g., inherent rigidity and basis weight) can be used.

EP 0 952 006 A2 shows a process for the production of pressure transmissions, an enclosure, a device for the production of the enclosure as well as a process for the production of the enclosure. The application discloses the packaging of printed items by a perfect wrapping with a specially cut as a packaging material sheet of paper or plastic, so a specific packaging product. Such a single sheet is intended for this purpose e.g. can be cut with a cutting unit and then folded, wherein flaps folded around folded edges can be connected to one another by means of adhesive application.

WO 2012/084 494 A2 shows a method for assembling a stack of loose superimposed precursors, the assembling of such precursors and an apparatus for producing such compilations. For this purpose, in a first step, the stack to be assembled from loosely superposed precursors is provided and in a second step a connecting element is attached to a stacking edge of the stack such that it overlaps the two outer precursors of the stack in an adhesive manner. This method provides a secure packaging for a variety of applications, but requires special fasteners to be glued.

The non-prepublished European Patent Application No. 15001321.7 was filed on 05.05.2015 in the name of Ferag AG and shows an apparatus for producing collections from a variety of different printed products. In each case, a part of the printed products is used as a packaging element, in which the other printed products are taken. In this way, handle units can be generated, which can be easily removed from a distributor manually from a transport container. In contrast to previously known methods for producing such collections, this method does not require any special additional packaging means, such as films or tapes. As a result, the costs of producing collections can be reduced and the amount of waste produced can be reduced. The said patent application shows several methods and devices for the production of such collections. One embodiment of a suitable transfer device comprises a brush roll having rotationally-curved bristles which deflects a portion of a packaging element which has previously been partially under an intermediate stack (e.g., pamphlets) at approximately right angles. This packaging section is bent back in a subsequent step on the intermediate stack as soon as the packaging element and the intermediate stack enter the space between two conveyor belts. Another handling device shown in the aforementioned application has rod-shaped drivers, which are rotated about an axis of rotation oriented transversely to the direction of movement of the unit of intermediate stack and packaging element. These drivers additionally perform an oscillating movement transversely to the conveying direction, which may require a relatively complex and / or maintenance-intensive mechanism or control. Both transhipment devices shown in the aforementioned application are suitable for a large number of transhipment products and intermediate stacks. However, with certain groups of envelope products and intermediate stacks - especially with relatively high inherent stiffness envelope products - the turnover may become unstable, i. tend to unwanted unfolding.

EP 2 462 043 B1 shows a folding unit and a method for folding a shingled stream of products in order to enable folding directly at the exit of a rotary printing press. For this purpose, the products should be folded so that each of the trailing products are partially arranged in the leading product. Accordingly, when folding the products, a product should always take along the trailing one and it should be folded in the direction of the side which is contacted flat by the subsequent product. This has the advantage, among other things, that shingled streams can be processed directly from the exit of the rotary printing press, without relocating them beforehand.

WO 2008/074 325 A1 shows a method for wrapping a stack of sheets, brochures or the like, in which the stacks are transported at a distance one behind the other on a transport path. By means of a special swivel wheel, a wrapping sheet is withdrawn from a stored sheet supply and positioned vertically in a gap between two successive stacks. Subsequently, the swivel wheel provides means that fold the sheet around the stack moving past. The complicated movement of the swivel wheel prevents a high processing speed of the stack.

PRESENTATION OF THE INVENTION

Known from the prior art methods and devices allow the handling or wrapping of precursors to hold them together. However, in the products or collections made by these processes, additives such as e.g. Adhesive dots necessary to ensure a sufficiently durable wrapping by the respective holding elements. This is e.g. then the case when relatively thick stacks of printed products are to be turned over. Likewise, in the case of products produced by these methods, the peak area of the folded cohesion element is often irregularly deformed. Thus, this area can be e.g. not be straight or have bumps. This is particularly problematic when a printed product is used as a cohesive element, as this is critically affected by its appearance. It is therefore an object of the invention to provide a simple method which allows for a turnover of first precursors with second precursors and efficiently prevents re-deployment of the handled product as compared to the prior art methods, as well as a cohesive element at a predefined location reverses in an advantageous and reproducible manner.

It is a further object of the invention to provide a device with which such a method can be performed.

These and other objects are achieved by the claims 1 and 14. Embodiments of the invention will become apparent from the dependent claims.

An embodiment of a method for producing a collection of precursors by inserting a first precursor into a second precursor according to the invention is characterized by the following steps: <tb> • <SEP> Providing a first precursor; <tb> • <SEP> providing a second precursor having a turn-up fold with a folded inside; conveying the second precursor into an insertion position in which the second precursor is provided for insertion of the first precursor and faces the first precursor with the folded inner side; <tb> • <SEP> conveying the first precursor into the provided second precursor and against the inside of the rebate to form the collection; <tb> • <SEP> the second precursor takes over the conveying direction of the first precursor; <tb> • <SEP> Provide the collection for further processing.

The further processing of the collection may e.g. promoting the collection and / or stacking multiple collections and / or addressing the collections.

According to one embodiment of the inventive method, the second precursors are not closed after the formation of the Umschlagefalzes to the formation of the collection. In this way, it is possible to dispense with an opening process which may be difficult to carry out in certain types of second precursors.

According to one embodiment of the inventive method, the first and / or second precursors may comprise a plurality of printed products. Such printed products may e.g. Advertising leaflets, brochures, magazines, flyers or printed sheets.

The individual printed products can be different printed products, which have different dimensions and / or weights from each other.

The first and second precursors may also comprise other products, such as samples.

In one embodiment of the method, the first precursor is conveyed in a conveying plane and the second precursor is provided in the conveying plane. This makes it possible to collect a plurality of printed products which differ greatly in their dimensions.

Good results can be achieved if the second precursor is conveyed in the conveying plane of the first precursor substantially perpendicular to the conveying direction of the first precursor in the insertion position. As a result, if necessary, the first and second precursors can be combined in a simple manner, without the promotion of the first precursors must be interrupted.

In a further embodiment of the method, the second precursor may have a primary fold (or folded edge). Such a primary fold (or folded edge) can be, for example, a fold and / or a stitching and / or a binding of a printed product.

Particularly short cycle times in the execution of the method can be achieved when a second intermediate product has a Primärfalz and is conveyed in advance in the insertion position with the Primärfalz.

In a further embodiment of the method, the second precursor comprises a plurality of printed products, each having a primary fold, wherein the printed products are oriented so that their primary fold is temporarily arranged during conveying in the insertion position.

A further embodiment is characterized in that the second precursor is not half-folded, but so that the Umschlag fold divides the second precursor into a larger and a smaller partial area. If a collection produced in this way is laid flat with the larger upper surface lying on the upper side, then the weight of this larger partial surface prevents a re-opening of the second intermediate product handled around the first intermediate product. As a result, in certain cases (if desired) can be dispensed with further fasteners (such as glue spots).

In one embodiment of the method, the second precursor can be provided during the conveying in the insertion position with the Umschlag fold. Such an embodiment has u.a. the advantage that (if desired) the same means for conveying as for folding can be used, whereby a device used to carry out the method can be constructed from fewer components. If required, however, the second precursor can also be folded or prefolded in an upstream step.

Alternatively or in addition, the second precursor can be provided before the conveying in the insertion position with the Umschlag fold.

The second precursor may also be a closed folded preform that is opened prior to forming the collection.

In one embodiment of the method, the movement of the collection takes place transversely to the orientation of the edge of the Umschlag fold of the second precursor.

According to a further embodiment of the method, a plurality of second precursors before delivery at least partially conveyed in a scaled arrangement in which a leading second precursor is arranged in each case above the trailing second precursor. In this way, the conveying speed of the second precursors can be reduced and certain second precursors can be conveyed better on curved sections.

In one embodiment of the method, a plurality of second precursors are conveyed in a folded and scaly arrangement, in which the outwardly directed after folding outward of a leading folded second precursor in each case partially on the inside after folding of the inside of the trailing second Preproduct is arranged. As a result, in particular prefolded second precursors can be opened in a simple manner for the combination with the first precursors, since the leading second precursors in each case support the keeping open of the second precursors trailing behind them.

In another embodiment of the method a plurality of second precursors are conveyed in a shingled arrangement, wherein the inside of a leading second precursor is partially disposed in each case on the outside of the trailing second precursor. This can be supported in certain second precursors of the folding and the promotion to the insertion position can be simplified.

In a further embodiment of the method, a collection can be promoted after its completion slower than the first precursor was promoted before the completion of the collection.

In one embodiment, collections are conveyed in a shingled arrangement, whereby the conveying speed of the collections can be reduced. In this case, trailing collection can e.g. each partially over a leading collection are arranged.

A particularly good merging of first and second precursors can be achieved if the promotion of the second precursor takes place in the insertion position against a stop element. Such a stop element may be the promotion of e.g. support and / or limit and thereby influence about the orientation of the second precursor relative to the first precursor, as will be explained in more detail below.

According to one embodiment of the invention N individual printed products are provided in an upstream process step, wherein the first precursor from N-x (x = 1, 2, 3 ...) of the N individual printed products is formed and the second precursor from the x remaining individual printed products is formed. As a result, the costs per manufactured collection can be reduced and additional waste generated by packaging materials can be avoided. The first precursors and second precursors are therefore similar in such an embodiment, so that the second precursors do not represent special or specific packaging means.

In particular, x = 1 may be in one embodiment of the inventive method, so the first intermediate product are handled by only a single printed product.

Particularly clean handled collections can be achieved when a manufactured collection is moved through a piecing device, in which the second precursor is pressed against the first precursor.

Good results can be achieved if the first precursor comprises a plurality of printed products having a preferred edge and the printed products are stacked so that their preferred edges together form a stack edge which forms an edge region which is against the Falzinnenseite of the second Pre-product is promoted. When manufactured according to such an embodiment of the method collections, the individual printed products when hand gripping the collection are particularly well secured against slipping out of the collection.

Collections which are particularly easy to grasp by hand can also be achieved if at least some of the individual printed products have a fold, a stitching or a binding and are placed on top of one another such that the folds or stitchings or bindings form a leading edge region which faces the inner fold side of the second precursor is conveyed. In this way, u.a. Reduce the risk that individual printed products fall out of the collection when the collection is picked up by hand.

A folded and / or stapled and / or glued edge can also be called fold edge.

In a further embodiment of this method, some of the printed products are to be arranged with their folded edge on the opposite side of the leading edge region in order to achieve a more uniform thickness of the first precursor.

In a further embodiment of the method can be taken as preferred edges of the printed products such edges, which are arranged on the opposite side of the folding edge.

Such an edge can also be called a flower.

If several or all of the printed products of the first precursor have such a flower, these printed products can be stacked on top of each other with the flowers, so that a leading edge region is formed from the flowers, which conveys against the inside of the folded second precursor becomes.

In another embodiment of this method, some of the printed products with their flower are to be arranged on the side opposite the leading edge region in order to achieve a more uniform thickness of the first precursor.

In a further embodiment of the method, at least some of the printed products on folding edges and are arranged stacked so that the folded edges together form a stack edge. The stack edge is arranged on the side opposite the leading edge region of the first precursor side, as will be explained in more detail below. Such an embodiment of the method may e.g. be advantageous if the first precursor printed products with divergent dimensions comprises, since thus the thickness of the leading edge region can be reduced, whereby the insertion of the first precursor is favored in the second precursor and a later unwanted reopening of the second precursor is counteracted.

In a further embodiment of the method, at least some of the printed products on flowers and are stacked arranged that the flowers together form a stacking edge, which is arranged on the opposite side of the first intermediate product promoted against the Falzinnenseite of the second precursor side of the first precursor ,

A device according to the invention for carrying out such a method generally comprises a first conveying device which conveys the first intermediate product into the opened second intermediate product located in the insertion position and against the inner side of the folded article. Likewise, it comprises a second conveying device, which conveys the second precursor into the insertion position.

In one embodiment of the device according to the invention, the first conveying device conveys a formed collection in the conveying direction of the first pre-product.

In a further embodiment of the device according to the invention, the first and the second conveying device have different conveying directions, which span a common conveying plane. With such a device, in particular first and / or second precursors of stacked printed products can be processed particularly gently.

A particularly reliable and rapid production of collections can be achieved if the first and the second conveying device are arranged so that their conveying directions are substantially perpendicular to each other. This is especially true when the first and second conveyor devices span a common conveyor plane, i. the second conveyor promotes the second precursors from one side into a transfer area into which the first precursors are pushed into the second precursors.

In such an embodiment of a device, the second precursors are conveyed substantially in the direction of the edge of Umschlagefalzes in the insertion position. The movement of the collection then takes place across the edge of the envelope fold.

In particular, such movement may be transverse to the edge of the envelope fold perpendicular to the edge of the envelope fold.

In a further embodiment of the device, the first and second conveying device clamp a horizontal common conveying plane.

Particularly clean Umschlagefalze can be achieved when the second conveyor is associated with a pressing unit, which folds the second precursor before reaching the insertion position.

In one embodiment of this aspect of the invention, the pressing unit comprises at least one press roller pair.

A particularly stable folding and at the same time an advantageous promotion in the insertion position can be achieved if the device comprises a press unit with two or more pairs of press rollers.

In a further embodiment of the invention, a press roller pair may comprise at least one segment roller, as will be explained in more detail below.

If necessary, a second precursor may be grooved prior to the production of the envelope fold.

If necessary, a second precursor can also have a plurality of turnover folds. This can be advantageous in particular for relatively thick first precursors, since in this way a refolding of the second precursors can be efficiently counteracted.

In one embodiment of the device, the device comprises a device which ensures the feedability of the supplied second precursor. Such a device may supply the supplied second precursor before and / or during conveyance into the insertion position, e.g. lead and / or open and / or align relative to the first precursor and / or hold, as will be explained in more detail below. Such a device may, for example, have ironing or plate-shaped elements, which reshape the second precursor so that it is opened. To support this opening process of the second precursor also compressed air can be used.

Particularly clean handled collections can be achieved if the device has a piecing device in which the second precursor is pressed against the first precursor. If necessary, such a piecing device can also effect a targeted compression of the collections to be produced.

Good results can be achieved if the piecing device has at least one press roller pair or press roller pair through which the collection is guided.

In order to precisely align the first and second precursor relative to each other, the device may have a stop member which limits the promotion of the second precursor in the insertion position. Such a stop element may e.g. include a stop bar or a stop slide.

Good results can be achieved if the stop element comprises at least one combination roller. Alternatively or in addition to the mentioned orientation of the second precursor, such a combination roller can if necessary promote the first and / or second precursor in the region of their combination and / or initiate and / or support the closing process of the second precursor after the introduction of the first precursor, as described below will be explained in more detail. In particular, such a combination roller can support if necessary a clamping promotion of the precursor. Particularly good results can be achieved if the combination roller is a tapered roller or truncated cone roller, or a roller with hemispherical profile, or role with a bell-shaped profile.

Good results can be achieved when a combination roller and a second conveyor are arranged to each other that a second precursor is promoted by the second conveyor until it is clamped between the combination roller and the first conveyor, and thereby further promotion is suppressed in the conveying direction of the second conveyor.

According to one embodiment, the first and / or second conveying device comprises belt conveyors. Such embodiments of the invention allow easy and safe transportation of many types of precursors and collections.

In one embodiment of a device according to the invention, the first conveying device comprises at least two transport paths lying in one plane, between which an at least temporary conveying gap is left free, in which the second precursor is brought into the insertion position. In this way, the second precursor can be particularly easily brought into the insertion position. Such an at least temporary conveying gap may be, for example, a gap in a belt conveyor.

In order to be able to process particularly heavy and / or soft first precursors, the device may comprise a conveyor table which conveys the first precursor into the second intermediate product located in the insertion position.

Alternatively or in addition, the first precursor during insertion into the second precursor can also be partially and temporarily raised from the conveying plane.

In a further embodiment of a device according to the invention, at least a portion of the second conveying device can be moved in the conveying direction of the first conveying device. In this way, when the first precursor is conveyed into the opened second precursor, the relative velocity between the first and second precursor may be set differently from the conveying speed of the first precursor. As a result, if necessary, a particularly gentle merging of the first precursors can be achieved, or it can be made particularly compact collections.

In order to prevent a reopening of the transferred second precursors, a device according to the invention may comprise a gluing device which glues the first and / or the second precursor so that they at least temporarily adhere to one another. using removable adhesives - e.g. as glue spots and / or glue beads.

WAYS FOR CARRYING OUT THE INVENTION

Figures 1 and 2 show schematically a first embodiment of an operating device according to the invention. The device has a horizontal first conveying device 11 with a conveying plane 17. The first conveying device 11 comprises a first transport path 12, are conveyed on the first precursors 1. The illustrated first precursors 1 are printed products 7, 7, 7. The first transport path 12 comprises spaced-apart belt conveyors, wherein the first precursors 1 are transported between the belts of the belt conveyors clamped. In order to transport first precursors 1 different dimensions, the upper of the two belt conveyors is spring-mounted in the vertical direction. The second transport path 13 is also essentially formed by a belt conveyor. As can be seen in FIG. 2, the illustrated device likewise comprises a second conveying device 14, with which second precursors 3 of the first conveying device 11 are conveyed laterally. In the embodiment shown in FIGS. 1 and 2, the second precursors 3 are conveyed by the second conveyor 14 at least in sections in a shingled arrangement. The second conveyor 14 may also include a folder such as e.g. in EP 2 462 043 B2. In the region of the second conveying device 14, a pressing unit 26 is arranged, which comprises two pressing roller pairs 27, 28. With these press roller pairs 27, 28, the second precursors 3 are conveyed on the one hand to the first conveying device 11 (shown schematically with the arrow), and on the other hand also folded, so that an envelope fold 4 is formed. For this purpose, the cylindrical press roller pairs 27, 28 compress the prefolded (or previously grooved) parts of the second precursor 3 in the region of the prefold and emboss or fix, thus the Umschlagfalz 4. Here, the closer to the first conveyor 11 arranged press roller pair rotates 28 faster than the other pair of press rollers 27, whereby the second intermediate product 3 to be conveyed into the insertion position is accelerated relative to the subsequent second precursors 3, whereby the scaly arrangement is resolved and only a single second precursor 3 is conveyed into the insertion position. During the folding process, the second precursors 3 are partly guided by a device 25 in order subsequently to enable the insertion of the first precursors 1. The device 25, also shown only schematically, consists of two bow-shaped guides which raise the part of the second precursor 3 lying in FIGS. 1 and 2 above the envelope fold 4 in the vertical direction upwards. The first and second conveying device 11,14 are synchronized with each other, so that the second conveyor 14 each promotes a second precursor 3 in the insertion position shortly before a first precursor 1 is conveyed into a transfer area 24, in which the two precursors 1, 3 are brought together , During this merger, the first precursors 1 are conveyed by a first combination roller 22 and partially fixed on the first transport path 12. A second combination roller 23 simultaneously helps to position the second precursor 3 in the conveying direction of the second conveyor 14 relative to the first precursor 1, and also to initiate the second precursor 3 after the merger the closing process. The device also has a support surface 29 in the transfer region 24, which supports the positioning of the second precursor 3, as will be explained in more detail below (compare FIGS. 9 and 10). The first and second conveying device 11,14 are synchronized so that when a second precursor 3 is in the insertion position in the transfer area 24, a first precursor 1 is promoted in the provided second precursor 3 and against the Falzinnenseite 5, whereby a collection 20 is formed becomes. The formed collections 20 are subsequently conveyed away on a second transport path 13. The collections 20 are guided through a stacking device 8, in which the second precursor 3 is tightly applied from two directions by means of press rolls 9, 10 to the first precursor 1.

The first precursors 1 shown in FIGS. 1 and 2 each consist of different combinations of stacked large, medium and small printed products 7, 7, 7. These each have a fold (or a folded edge) and are stacked arranged so that their folds / fold edges form a leading stack edge 2, which in the merger of the first and second precursors 1, 3 respectively against the Falzinnenseite 5 of the associated second precursor 3 is promoted. The flower of the largest printed product 7 forms a trailing stacking edge 6. Dermassen constructed first precursors 1 allow safe handling of a second precursor 3 to all to be wrapped printed products 7, 7, 7. This can be avoided that when hand picking a finished collection 20 individual printed products 7, 7, 7 fall out of the collection. A simple gripping of all precursors by means of a handle is ensured in this type of collections.

The embodiment of a device according to the invention shown schematically in FIGS. 3 and 4 is essentially the same as the device shown in FIGS. 1 and 2. However, the printed products 7, 7, 7 arranged here stacked so that their flowers form a trailing stack edge 6. The first precursors 1 stacked in this way are conveyed respectively into the provided second precursor 3 and against the folded inner side 5 with the folded edge of the printed product 7 at the bottom, which forms a leading edge of the first precursor 1. A method with stacked first precursors 1 constructed in this way can be advantageous for being able to convert first precursors 1 having a relatively large total thickness (or large maximum stack height). Since such first precursors 1 have a reduced thickness (or height) in the region of the leading edge, the insertion is simplified. In addition, handled second precursors 3 thus remain better in the handled state. At the same time, due to the stack edge 2 formed on the flowers on the one side and the folded second precursor 3 on the other side, such collections 20 can have a precisely defined external shape, which simplifies their further processing.

The embodiment of a device according to the invention shown schematically in FIGS. 5 and 6 is in turn constructed similar to the devices shown in FIGS. 1 to 4. The printed products 7, 7, 7 of the first precursors 1 in turn each have a fold (or a folded edge) and are arranged stacked so that their folds / folded edges form a leading stack edge 2. However, the second precursors 3 are not supplied here in a scaly arrangement, but isolated. Such an embodiment of the invention may be advantageous in order to process, for example, particularly large and / or heavy second precursors 3. The device shown also has a relatively large support surface 29, which is shown in FIGS. 1 to 4, which also supports the manufactured collections 20 when they are guided through the stacking device 8. The first precursors 1 are constructed in the same way as the first precursors 1 shown in FIGS. 1 and 2.

The embodiment of a device according to the invention shown schematically in FIGS. 7 and 8 is constructed analogously to the device shown in FIGS. 5 to 6. The printed products 7, 7, 7 of the first precursors 1 are again arranged stacked in such a way that their flowers form a trailing stack edge 6. However, here are the first precursors 1 constructed in the manner shown in Figs. 3 and 4.

9 shows a perspective view of a further embodiment of a device according to the invention with a press unit 26, comprising a first and second press roller pair 27, 28, which at least supports the formation of a Umschlag fold 4 in the second precursor 3. Both the press unit 26 shown, as well as the first and the second press roller pair 27, 28 contained therein can be considered in combination or individually as a separate inventive concept. As such, in particular, both the press unit 26 with the two press roller pairs 27, 28 as shown in combination with each other or the two pairs of press rollers 27, 28 individually taken in each case in other embodiments of the invention devices can be used. The first press roller pair 27 includes upper and lower cylindrical press rollers 31, 32, whereas the second press roller pair 28 has a lower cylindrical press roller 34 and an upper segment roller 33 having a circumferentially varying radius. The segmented roller 33 has an area (conveying segment) with an increased radius, which is configured such that a second precursor 3 arranged between the second pair of pressing rollers 28 can be conveyed in a clamping manner in the direction of the first conveying device 11 or of the transfer area 24. The second press roller pair 28 may be arranged to fold (or stamp) a second precursor 3 passing through it by the press rollers 33, 34, or e.g. previously introduced by the first pair of press rollers 27 folding the Umschlagefalzes 4 is amplified. In particular, however, the second press roller pair 28 can also be designed so that it does not substantially change an existing turn-up fold 4, but primarily serves to convey the already folded second feed product 3. By using such a segmented roller 33, it is possible to temporarily promote a second precursor 3 until shortly before the merger with the first precursor 1 (or safely convey it until the insertion position is reached), but the clamping will be safe after the collection 20 has been produced repealed. Such a second press roller pair 28 can therefore also be arranged in the transfer area 24 between the first and second transport path 12, 13 without the conveyance of the first precursors 1 or of the collections 20 being impaired thereby. The second precursors 3 are also folded in such a way that the parts of the crimped second precursors 3 lying above the first precursors 1 in FIG. 9 are larger than the parts lying below the first precursors 1. As a result, it is prevented in the illustrated horizontal collections 20 that the second precursors 3 unfold again.

10 schematically shows the transfer area 24 in which a collection (not shown) is produced from a first and a second precursor 1, 3. For this purpose, the second precursor 3 is clamped by a press unit 26 so that an envelope fold 4 is formed. At the same time, the second precursor 3 thus folded is conveyed into the illustrated insertion position. In this case, the second precursor 3 is guided in the illustrated area above the Umschlag 4 by the existing of two round profiles device 25 and held in the open state. Below the Umschlag fold 4, the second precursor 3 is guided by a support surface 29. As soon as the second precursor 3 is in this insertion position, the first intermediate product 1 is conveyed by the belt conveyor of the first transport section 11 into the opened second intermediate product 3 and against the inner side 5 of the folded sheet, whereby a collection (not shown) is formed. This is then fed by the belt conveyor of the second transport path 13 of the further processing.
