Falztisch für Maschinen zum Falzen von Leporelioblocks.Folding table for machines for folding Leporelio blocks.

Patentiert im Deutschen Reiche vom 5. Januar 1908 ab.Patented in the German Empire on January 5, 1908.

Die Erfindung bezieht sich auf solche Maschinen zum Falzen von Leporelioblocks, bei welchen das Falzen der in den Falzstellen gelochten Papierbahn durch zwei zu beiden Seiten derselben abwechselnd hin und her bewegte Falzschienen bewirkt wird. Durch einen den Gegenstand der Erfindung bildenden besonders eingerichteten beweglichen Falztisch wird der Zweck verfolgt, das Falzen der Papierbahn unabhängig von dem sich aus den gefalzten Teilen, derselben bildenden Stapel bewirken und somit letzteren von Zeit zu Zeit ungehindert unter der Falzvorrichtung fortnehmen zu können.The invention relates to such machines for folding Leporelioblocks, at which the folding of the paper web perforated in the folds by two on both sides the same folding rails moved alternately back and forth is effected. Through a the subject of the invention forming specially equipped movable folding table the purpose of the folding of the paper web is independent of what results from the folded parts, the same forming stacks and thus the latter from time to time to be able to take away unhindered under the folding device.

Zu diesem Zwecke ist unterhalb der Falzschienen ein aus zwei Tischplatten bestehender Falztisch angeordnet worden, dessen beide Platten derart abwechselnd hin und her bewegt werden, daß sich immer beim Vorwärtsgang einer der Falzschienen von entgegengesetzter Seite her eine der Tischplatten darunterschiebt, um dem zu falzenden Teil der Papierbahn als Unterlage zu dienen. Auf der Tischplatte wird dann der jeweils gebildete Falz durch eine geeignete Druckvorrichtung so lange festgehalten, bis auf der beim Vorwärtsgang der anderen Falzschiene entgegengescho-For this purpose, a table consisting of two table tops is located below the folding rails Folding table has been arranged, the two plates of which moved back and forth in this way that one of the folding rails is always from the opposite side when moving forward Slide one of the table tops underneath it, around the part of the paper web to be folded to serve as a base. The fold that has been formed is then placed on the tabletop held by a suitable pressure device until the forward gear facing the other rabbet rail

, benen anderen Tischplatte der nächste Falz gebildet ist und darauf durch die entsprechende Druckvorrichtung festgehalten wird, worauf plötzlich die vorher benutzte Tischplatte aus dem Bereich des darauf liegenden Falzes zurückgeschoben wird, so daß dieser frei nach unten kippt. Indem so die fertiggefalzten Blatteile der Papierbahn abwechselnd von den aus ihrem Bereich zurücktretenden Tischplatten nach unten kippen, schichten sie sich auf einem besonderen tief liegenden Sammeltische zu einem Stapel auf und können von dort nach Belieben fortgenommen werden. , benen another table top the next fold is formed and on it by the corresponding Printing device is held, whereupon suddenly the previously used table top is pushed back from the area of the fold lying on it, so that it tilts freely downwards. By doing so the finished folded Sheet parts of the paper web alternate with those receding from their area Tilt the tabletops down and layer them on a special low-lying collecting table in a stack and can be removed from there as desired.

Auf beiliegender Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt.The subject of the invention is shown in an exemplary embodiment in the accompanying drawing shown.

Fig. 3 veranschaulicht einen Teil der Vorrichtung in Ruhestellung.Fig. 3 illustrates part of the device in the rest position.

Die beiden beweglichen Tischplatten α und b sind an den unteren, winklig umgebogenen Enden von Hebeln c und d befestigt, die zu je zweien auf parallel zu den Zugwalzen e, f in den Seitenwangen g und h des Maschinengestelies gelagerten Wellen i und k festsitzen. Auf denselben Wellen sitzen außerdem Hebelarme I, m fest, die durch eine Zugfeder η miteinander verbunden sind und Gleitrollen 0, p tragen. Durch die Spannung der Zugfeder η werden die Rollen 0, p ständig mit , dem Umfang von auf den Wellen der Zugwalzen e, f festsitzenden Hubscheiben q, r in Berührung gehalten, so daß die Hebel c, d mit den Falztischen a, b einerseits unter dem Einfluß der sich mit den Zugwalzen drehenden Hubscheiben q, r, andererseits unter dem Einfluß der Zugfeder η hin und her geschwenkt werden.The two movable table tops α and b are attached to the lower, angularly bent ends of levers c and d , two of which are stuck on shafts i and k , which are mounted parallel to the pulling rollers e, f in the side walls g and h of the machine frame. Lever arms I, m , which are connected to one another by a tension spring η and carry sliding rollers 0, p , are also firmly seated on the same shafts. The tension of the tension spring η keeps the rollers 0, p in contact with the circumference of the lifting disks q, r fixed on the shafts of the draw rollers e, f , so that the levers c, d with the folding tables a, b on the one hand below the influence of the lifting disks q, r rotating with the pulling rollers, on the other hand, can be pivoted back and forth under the influence of the tension spring η.

effect ken of compression springs w, χ by means of levers i, 2 and steering rods 3, 4 equipped with rollers y, ζ. The levers i, 2 are mounted on the side wall h. The handlebars 3/4 are connected to arms 5, 6, which are firmly seated on the shafts 7, 8, some of which are flattened and which carry the compression springs.

Whenever one of the folding rails 9, 10 moves forward in order to strike a new block sheet of the paper web 11 flat in a straight plane, the corresponding table top α or b pushes itself tightly under the paper, so that this is under a certain gentle pressure on the table surface is flattened. When the folding rail has reached the feed limit, the corresponding compression springs w or χ move downwards and press the fold that has formed onto the table top, for which purpose the folding rails are provided with slots in the oscillation range of the compression springs so that the compression springs enter the slots and can press directly on the newly formed fold without the fold rail itself being touched by the compression springs. The folding rail can thus be moved backwards freely and unhindered. During the entire backward movement of the folding rail that has been in operation or during the entire forward movement of the other folding rail coming into operation, the previously formed fold remains pressed on the table top underneath, and that until "until the next fold is on the opposite side The other table top, pushed under the paper, is also firmly pressed by the corresponding pressure springs that go down.In this working stage, the parts are shown in Fig. 1. The folding rail 10 has just reached the limit of its advance to the left and a new one

'Fold formed in the paper web 11. The same is pressed firmly on the table top α by the compression springs w. Likewise, the fold previously formed by the folding rail 9 is still pressed on the table top b by the compression springs χ. Since the pulling roller f with the lifting disk r now turns to the left, the flattened part of the lifting disk r comes in front of the roller p in the next instant, so that this and the arm m move to the left under the tension of the spring η, while the Swing lever d with table top b outwards. In the process, the fold that has been firmly pressed on this table top loses its base and tilts down into a position opposite to that which the fold 12 has. The fold newly formed by the folding rail 10 now remains on the table top α by the compression springs w - pressed down until the folding rail 9 has finished its advance to the right and has formed a new fold and the latter on the table top b, which is now swinging inward again, by the compression springs χ is firmly pressed. In the meantime, the concentric part of the clockwise rotating lifting disk q has run out on roller 0 , and the flattened part of this lifting disk passes in front of roller 0, so that it and arm I move to the right under the action of spring η and the levers c swing outwards with the table top α to the left. As a result, the fold that has been firmly pressed on this table top loses its support and tilts into the position which the fold 12 has.

Each time one of the table plates away swings in the rest position, also move under the pressure of the thumb corresponding Su s or t w, the corresponding compression springs or χ upward. In this rest position, the table top α and the compression springs w are illustrated by FIG. 3. The folding rail 10 is on the way to the left in order to form a new fold. In the above-described, uninterrupted repetitive game of the parts, the block sheets are stacked in the manner shown in FIG. 1 on a special collecting table attached to a suitably deep location, and the blocks can be conveniently removed from there.

In order to enable each table top to move into the working position before the end of the advance of the corresponding rebate rail and to remain there a little over the entire duration of the return movement of the same rebate rail or the advance of the other rebate rail, so that each newly formed rebate rail is retained If the fold remains pressed down until the next one is complete and defined, each of the lifting disks q and r is only flattened on a part of its circumference that is significantly less than half the amount.

Instead of the oscillating lever, other suitable transmission means can of course also be used can be used to achieve a correspondingly regulated, reciprocating movement of the table tops.
