Tiegeldruckpresse für Schön- und Widerdruck auf Bahnen.Platen printing press for perfecting on webs.

Patentiert im Deutschen Reiche vom 6. Januar 1910 ab.Patented in the German Empire on January 6, 1910.

Den Gegenstand vorliegender Erfindung bildet eine Tiegeldruckpresse für Schön- und Widerdruck auf Bahnen, bei welcher feststehende Schriftformen verwendet werden, über denen sich eine gemeinsame Druckplatte senkrecht. parallel auf und ab bewegt. Die Anordnung ist hierbei so getroffen, daß die endlose Papierbahn beim Niedergang der Druckplatte gleichzeitig auf beiden Seiten bedruckt wird, so daß beiThe subject matter of the present invention is a platen printing press for perfecting printing on webs in which fixed writing forms are used, over which a common pressure plate vertically. moves up and down in parallel. The arrangement is here taken so that the endless paper web at the same time as the pressure plate descends is printed on both sides, so that at

ίο Anordnung von zwei Schriftformen in der Maschine in einem Arbeitsgang acht Seiten und bei vier Schriftformen i6 Seiten gedruckt werden können.
Der Zweck der nach der Erfindung gebauten Maschine besteht in der Hauptsache darin, daß der durch die Platte erzeugte Druck eine erhebliche Zeitersparnis gegenüber den gebräuchlichen Schnellpressen bedeutet, da sich der Zylinder erst auf der Papierbahn abwälzen muß.ίο Arrangement of two fonts in the machine, eight pages can be printed in one operation and with four fonts i6 pages can be printed.
The main purpose of the machine built according to the invention is that the pressure generated by the plate means a considerable saving of time compared to the customary high-speed presses, since the cylinder must first roll on the paper web.

In den beiden Seitenwänden 1 des Maschinengestells sind die beiden Schriftformen 2 und 2^a festgeschraubt, welche in einer Ebene liegen und parallel zueinander angeordnet sind. Jede Druckform weist die beiden Schienen 3 und 3^a auf, damit der einzuschiebende Drucksatz gegen seitliche Verschiebung gesichert ist. Über der Druckform läßt sich die Druckplatte 4 in der Höhenrichtung parallel hin und her bewegen. Die Druckplatte 4 hat an ihren vier Ecken je ein Auge 5, welches in je einer der Stangen 6 gleitet. Die Stangen 6 werden in den Naben 7, welche sich im Innern der Seitenwände 1 des Maschinengestells befinden, gehalten. In der Mitte der Druckplatte 4 befinden sich noch rechts und links außerhalb der Seitenwände die Augen 8, in welchen je eine Stange 9 befestigt ist. Am unteren Ende der Stange 9 befindet sich die Schleife 10, in welcher das Lager 11 mit dem Kurbelzapfen 12 hin und her gleitet. Die Kurbel 12 sitzt, auf der Welle 13 und wird mit derselben durch das Zahnrad 14, das ebenfalls auf der Welle 13 befestigt ist und in das Zahnrad 15 der Antriebswelle 16 greift, in Drehung versetzt. Auf diese Weise wird die Druckplatte 4 zwangläufig über den feststehenden Druckfundamenten parallel auf- und abwärts bewegt.In the two side walls of the machine frame 1, the two forms of signature 2 and ^2a are screwed, which lie in one plane and are disposed parallel to each other. Each printing form, the two rails 3 and 3 ^a, to be inserted so that the print set is secured against lateral displacement. The printing plate 4 can be moved back and forth parallel in the height direction over the printing form. The pressure plate 4 has an eye 5 at each of its four corners which slides in one of the rods 6. The rods 6 are held in the hubs 7, which are located in the interior of the side walls 1 of the machine frame. In the middle of the pressure plate 4 are the eyes 8, in each of which a rod 9 is attached, to the right and left outside the side walls. At the lower end of the rod 9 is the loop 10 in which the bearing 11 with the crank pin 12 slides back and forth. The crank 12 sits on the shaft 13 and is set in rotation with the same by the gear wheel 14, which is also fastened on the shaft 13 and engages in the gear wheel 15 of the drive shaft 16. In this way, the pressure plate 4 is inevitably moved up and down in parallel over the fixed pressure foundations.

Ferner sind an der Druckplatte 4 noch die beiden Zurichtplatten 17 supportartig befestigt. Dieselben können durch den Handgriff 18 aus der Platte seitlich herausgezogen werden, um eine schnelle und leichte Zurichtung zu ermöglichen. Furthermore, the two dressing plates 17 are attached to the pressure plate 4 in a support-like manner. The same can be pulled out of the plate by the handle 18 to the side to enable quick and easy set-up.

Von der Papierrolle 19, welche bei 20 gelagert ist, wird die Papierbahn 21 abgewickelt (Fig. ι und 3) und zunächst zwischen einer Anfeuchtvorrichtung hindurchgeführt. Die Anfeuchtvorrichtung besteht aus den beiden Kästen 22 und 22^a, welche mit Wasser gefüllt sind und einen siebartig mit Löchern ausgestatteten Boden aufweisen, durch welchen das Wasser auf zwei Filzwalzen o. dgl. tropft, so daß die Papierbahn ständig auf beiden Seiten angefeuchtet wird.From the paper roll 19, which is stored at 20, the paper web 21 is unwound (FIGS. 1 and 3) and first passed between a moistening device. The moistening device consists of the two boxes 22 and 22 ^a , which are filled with water and have a sieve-like bottom equipped with holes through which the water drips onto two felt rollers or the like, so that the paper web is constantly moistened on both sides.

Dann wird die Papierbahn weiter über die Schleifenbilderwalze 24, welche in zwei Armen 25 gelagert ist, geführt. Die Arme 25 sind gelenkigThen the paper web is passed over the loop forming roller 24, which is in two arms 25 is stored, led. The arms 25 are articulated

Claims

attached to the pressure plate 4 and are under j spring action. When the pressure plate goes down slide the same on the attached to the two side walls of the machine frame Rod 26, releasing as much paper of the paper web as the downward movement of the Pressure plate 4 required. During the upward movement, the loop pattern reverses as a result of the spring action back to the old position and winds this from the paper roll 19 für.die the following downward movement of the printing plate off the paper. In this way a permanent one takes place Transport control of the paper web takes place while the paper web is constantly tensioned.

t5 From the Schleifenbüder roller 24 comes the Paper web 21 through the recess in the printing plate over the guide rollers 23 under the dressing plate 17 in the direction of the arrow after the two impregnating rollers 27.

The transport rollers 27 are driven from the drive shaft by belts, chains or the like. emotional. From the transport rollers 27, the paper web is then over the guide roller 28 and 28 "to the other half of the machine; here it first runs over one further loop images 24 ^ and then through a central recess in the pressure plate 4 through under the pressure plate over various guide rollers 29 after the rollers 30, which accommodate the printed paper and set up in a known manner Feed the folding and cutting device, from where it is then used as a finished printed matter, newspaper, or the like. falls out (Fig. 1 and 3). ■

In the middle of the machine as well as to the right and left of the printing plate there is an inking unit 31, which constantly provides ^{the rollers 32 and 32 s with ink} Frame are connected, which moves horizontally back and forth, get under the inking units 31 during this movement, which transfer their color to the rollers 32. The rollers 32 then transfer the color on to the applicator rollers 32 ^ and these in turn color the two documents which rest on the writing forms. The inking rollers are moved by the two connecting rods 34, which are located outside the side walls and are rotatably attached to the arms 33 at 35, while the same are mounted at their other end in the crank pin 36 of the crank 37. The cranks 37 sit on the shaft 38 and are moved by the gear 39, which is also seated on the shaft 38 and is in engagement with the gear 40 of the shaft 13. Furthermore, the rails 41 are also arranged on the side walls, in which the arms 33 with the inking rollers 32 and 32 ^{a are} inevitably guided during their movement.

The 'mode of operation of the machine is now as follows:

The printing plate 4 is moved by the crank 12 up and down in an uninterrupted sequence over the fonts 2 and 2 ^a , so that a constant printing of the corresponding further moving paper web 27 takes place. The printing takes place here constantly on both sides of the paper web by the front side of the paper web is printed on the writing 2 of one machine half, while at the same time, ie in the same operation of the machine, the other side of the paper web through the on the writing 2 ^a dormant pleading receives a copy. When the printing plate descends, the loop image rollers 24 and 24 ^s release as much paper as the lifting height of the printing plate makes, while after the impression has been made, the upward movement of the printing plate pulls the paper corresponding to the lifting height off the paper roll 19 again. After each up and down movement of the printing plate 4, the frame slides with the ink rollers 32 and 32 ^a over the documents resting on the two font foundations 2 and 2 ^{a in} order to provide them with fresh paint. As soon as the frame has made its way over the two sets of documents, one end of it comes under the inking unit 31 arranged on the right or left of the printing plate, while the other end of the frame comes to stand under the inking unit 31 arranged in the middle, from where the paint rollers 32 receive fresh paint that is transferred to the rollers 32 ^.

The inking units 31 can also be arranged in the interior of the side walls parallel to them, so that the frame with the rollers 32 and 32 ^a does not, as indicated in the exemplary embodiment, take its path in the length of the machine, but in the width of the machine and moved here. In this case only two inking units are necessary.

Of course, the press is also provided with all other accessories, but which, as they do not belong in the scope of the invention, are omitted. .
