Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung eines zusätzlichen Falzes in Falzapparaten von Rotations­druckmaschinen gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for producing an additional fold in folders of rotary printing presses according to the preamble of claim 1.

Falzvorrichtungen der obengenannten Art sind bekannt. Das Falzen erfolgt bei voller Papierlaufgeschwindigkeit mittels einem rotierenden Falzmesser, das aus der Oberfläche einer umlaufenden Trommel heraustritt, wobei die Falzmesserspitze das zu falzende Druckexemplar resp. Druckexemplarpaket in zwei gegenläufig angetriebene Falzwalzen stösst. Nachteilig ist bei diesen Vorrichtungen das Wegfalzen bei hoher Papier­laufgeschwindigkeit. Dies führt durch den dabei auftretenden Peitscheneffekt an den nachlaufenden Enden der Druckexem­plare zu Beschädigungen.Folding devices of the type mentioned above are known. Folding takes place at full paper running speed by means of a rotating folding knife that emerges from the surface of a rotating drum, the folding knife tip being the printed copy to be folded or Print copy package pushes into two oppositely driven folding rollers. A disadvantage of these devices is the folding away at high paper running speed. This leads to damage due to the whip effect that occurs at the trailing ends of the printed copies.

Aus der DE-OS 28 46 191 ist ein Verfahren bekannt geworden, bei welchem die zu falzenden Exemplarpakete auf zwei analoge Falzvorrichtungen verteilt und damit die Falzgeschwindig­keiten halbiert werden, was zum Abbau des Peitscheneffektes führen soll. Ein Falzapparat nach diesem Verfahren ist aber sehr aufwendig, da er für den zusätzlichen Falz zwei Falz­vorrichtungen benötigt.From DE-OS 28 46 191 a method has become known in which the copy packages to be folded are distributed over two analog folding devices and thus the folding speeds are halved, which should lead to the reduction of the whip effect. However, a folder using this method is very complex since it requires two folding devices for the additional folding.

Aufgabe der Erfindung ist es, eine Falzvorrichtung der vor­genannten Art zu schaffen, bei welcher der unvermeidlich auftretende Peitscheneffekt an den nachlaufenden Enden der Druckexemplare, ohne an den Druckexemplaren Beschädigungen zu hinterlassen, ausflattern kann.The object of the invention is to provide a folding device of the aforementioned type, in which the inevitable whip effect occurs at the trailing ends of the Can print out printed copies without leaving any damage to the printed copies.

Erfindungsgemäss erfolgt die Lösung der Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 aufgeführten Merkmale.According to the invention the object is achieved by the features listed in the characterizing part of claim 1.

Mit dieser Ausgestaltung der Falzwalzen wird vermieden, dass durch den Peitscheneffekt hervorgerufene Faltungen nicht eingewalzt werden.With this configuration of the folding rollers, it is avoided that folds caused by the whip effect are not rolled in.

Besonders vorteilhaft ist, wenn das mittlere Drittel der Druckexemplarlänge durch stehengelassene Restflächen der Falzwalzenoberfläche zusätzlich mit den Bändern geführt ist, ohne dass der Mittelteil des Druckexemplares zwischen den Falzwalzen noch ausgewalzt wird. Dadurch sind hohe Falzge­schwindigkeiten in hoher Falzqualität möglich.It is particularly advantageous if the middle third of the length of the printed copy is additionally guided with the tapes by remaining areas of the folding roller surface without the middle part of the printed copy being rolled out between the folding rollers. This enables high folding speeds in high folding quality.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt und wird nachfolgend beschrieben.In the drawing, an embodiment of the invention is shown and will be described below.

Es zeigen:

  • Fig. 1 einen Aufriss der Vorrichtung bei Beginn des Falz­vorganges des Exemplares
  • Fig. 2 einen Aufriss der Vorrichtung bei Ende des Falzvor­ganges des Exemplares
  • Fig. 3 eine räumlich dargestellte Ansicht einer Falzwalze
Show it:
  • Fig. 1 is an elevation of the device at the beginning of the folding process of the specimen
  • Fig. 2 is an elevation of the device at the end of the folding process of the specimen
  • Fig. 3 is a spatially illustrated view of a folding roller

Die nach Fig. 1 auf einem Falztisch 1 ankommenden Druckexem­plare 2 werden durch die Spitze des Falzmessers 3 zwischen die auf bekannte Art gegenläufig angetriebenen und symme­trisch angeordneten Falzwalzen 4 und 5 gedrückt. Jede der Falzwalzen 4 und 5 treibt ein Transportbandsystem 6, 7 an. Die Falzwalzen 4 und 5 sind je auf einem Paar von Schwenk­ hebeln 8 bzw. 9 drehbar angebracht. Die Schwenkhebel 8 bzw. 9 sind um die Drehpunkte 10 bzw. 11 schwenkbar gelagert. Durch Einstellmechanismen 12 lässt sich der Falzspalt zwi­schen den Falzwalzen 4 und 5 durch Schwenken der Schwenk­hebel 8 und 9 jeweils der Dicke des zu falzenden Druckexem­plars 2 anpassen.1 arriving on a folding table 1 printed copies 2 are pressed by the tip of the folding knife 3 between the counterclockwise driven and symmetrically arranged folding rollers 4 and 5. Each of the folding rollers 4 and 5 drives a conveyor belt system 6, 7. The folding rollers 4 and 5 are each on a pair of swivel lever 8 or 9 rotatably attached. The pivot levers 8 and 9 are pivotally mounted about the pivot points 10 and 11. The folding gap between the folding rollers 4 and 5 can be adjusted by adjusting the mechanisms 12 by pivoting the pivot levers 8 and 9 to the thickness of the printed copy 2 to be folded.

Die Falzwalzen 4, 5 ergreifen das durch das Falzmesser 3 in den Falzspalt eingebrachte Druckexemplar 2, bilden den Falz 32 und führen das Druckexemplar 2 mit Hilfe des Transport­bandsystems 6, 7 dem Auslegerrad 13 zu.The folding rollers 4, 5 grip the printed copy 2 introduced into the folding gap by the folding knife 3, form the fold 32 and guide the printed copy 2 to the delivery wheel 13 with the aid of the conveyor belt system 6, 7.

Wie auch Fig. 2 zeigt, weisen die Falzwalzen 4 und 5 Aus­sparungen 14 bzw. 15 auf. Diese Aussparungen 14 und 15 er­möglichen, dass das nachlaufende Ende 16 des Druckexemplars 2 frei ausflattern kann, während das Druckexemplar 2 durch die Bänder 17 und 18 des Transportbandsystems 6, 7 dem Aus­legerrad 12 zugeführt wird.2 also shows, the folding rollers 4 and 5 have cutouts 14 and 15, respectively. These cutouts 14 and 15 enable the trailing end 16 of the printed copy 2 to flutter freely, while the printed copy 2 is fed to the delivery wheel 12 through the belts 17 and 18 of the conveyor belt system 6, 7.

Fig. 3 zeigt schematisch, wie die Falzwalzen 4 bzw. 5 ge­staltet sind. Zur Verdeutlichung wurde ein Druckexemplar 2 gestrichelt eingezeichnet, um zu zeigen, welcher Bereich des Druckexemplars 2 wo die Falzwalze 4 bzw. 5 berührt. Die Falzwalze 4 bzw. 5 ist mit ihren Achsen 19 und 20 in den Schwenkhebelpaaren 8 bzw. 9 drehbar und antreibbar gelagert. Der den Falz des Druckexemplars 2 bildende Teil 21 der Falz­walzenoberfläche ist durchgehend ausgeführt und weist ledig­lich Einschnitte 22 und 23 zur Führung der Bänder 17 bzw. 18 auf. Dieser den Falz des Druckexemplars 2 bildende Teil 21 erstreckt sich in Abrollrichtung gesehen etwa über einen Drittel der Länge des Druckexemplars 2.Fig. 3 shows schematically how the folding rollers 4 and 5 are designed. For the sake of clarity, a printed copy 2 was drawn in with a broken line to show which area of the printed copy 2 touches where the folding roller 4 and 5, respectively. The folding roller 4 and 5 is rotatably and drivably mounted with its axes 19 and 20 in the pairs of pivot levers 8 and 9, respectively. The part 21 of the folding roller surface which forms the fold of the printed copy 2 is continuous and has only incisions 22 and 23 for guiding the strips 17 and 18, respectively. This part 21 forming the fold of the printed copy 2 extends in the unwinding direction over approximately a third of the length of the printed copy 2.

Der an den Teil 21 der Falzwalzen 4 bzw. 5 sich anschlies­sende Bereich 24 ist mit einer Aussparung 25 versehen, die links und rechts von den Restflächen 26 und 27 begrenzt ist. Die Breite der Aussparung 25 ist so bemessen, dass das Druck­ exemplar 2 beidseitig mit den Randzonen auf den Restflächen 26 und 27 zum Aufliegen kommt. In der Aussparung 25 sind Führungsringe 28, 29 zur Auflage für die Bänder 17 bzw. 18 angeordnet.The area 24 adjoining the part 21 of the folding rollers 4 and 5 is provided with a cutout 25 which is delimited on the left and right by the remaining areas 26 and 27. The width of the recess 25 is dimensioned so that the pressure example 2 comes to rest on both sides with the edge zones on the remaining surfaces 26 and 27. In the recess 25 guide rings 28, 29 are arranged to support the bands 17 and 18, respectively.

Die Länge des Bereiches 24 entspricht etwa einem Drittel der Länge des Druckexemplars 2, d.h. dass der zweite Drittel des Druckexemplars in Abrollrichtung gesehen diesen Bereich 24 abdeckt.The length of the area 24 corresponds to approximately one third of the length of the printed copy 2, i.e. that the second third of the printed copy, viewed in the unwinding direction, covers this area 24.

Der letzte Bereich 30 der Falzwalzen 4 bzw. 5, auf den der Endabschnitt 31 des Druckexemplars 2 zu liegen kommt, ist über die ganze Breite der Falzwalzen 4 bzw. 5 ausgespart. Ueber diesen Bereich 30 erstrecken sich nur die Führungs­ringe 28, 29 zur Auflage für die Bänder 16 bzw. 17.The last area 30 of the folding rollers 4 and 5, on which the end section 31 of the printed copy 2 comes to rest, is recessed over the entire width of the folding rollers 4 and 5. Only the guide rings 28, 29 extend over this area 30 to support the bands 16 and 17, respectively.

In diesem Bereich 30 kann das nachlaufende Ende des Druck­exemplares 2 frei ausflattern. Die durch den Peitscheneffekt und durch das dadurch entstehende Flattern der Druckexemplare 2 hervorgerufenen Falten werden nicht eingewalzt, sondern sie glätten sich beim Weitertransport der Druckexemplare 2, da diese nur durch die Bänder 17 und 18 gehalten sind.In this area 30, the trailing end of the printed copy 2 can flutter freely. The folds caused by the whip effect and the resulting fluttering of the printed copies 2 are not rolled in, but they are smoothed out when the printed copies 2 are transported, since these are only held by the belts 17 and 18.
