Description

When producing magazines in rotary printing machines, they are given lengthways and crossways folded sheet a further longitudinal fold. For this purpose it is common practice to use the cross fold Stopping incoming sheets lying flat on a folding table and using rotating folding knives or folding cylinders to fold. Now the desire to have such magazines at the same time as a To provide stapling. However, it is not possible to fold the products from the transverse to the longitudinal fold in Stapling the direction of the paper because there is no suitable stapler. Therefore it is necessary to arrange the folding device so that the folding sheets through one of the proven cross staplers can be stapled.

In order to achieve this, the invention takes the path that comes from the transverse fold and through stops stopped folding sheets transversely to their previous running direction and a cylinder folder to be handed over, which allows cross stitching without further ado. In the area of Folding table according to the invention arranged rotating segment discs, which the stopped folding sheets continue to convey transversely to their previous running direction and one that works together with a wire stapler Hand over the folding cylinder.

In this way, the production of stapled magazines is made possible with simple means. In particular the stapling takes place before the last longitudinal fold of the products at high performance and using the tried and tested wire stapling devices of the usual design and arrangement.

The drawing illustrates an embodiment of the invention and shows in

Fig. 1 shows a folding table with a longitudinal folder of known arrangement and in

Fig. 2 the folding table and a cylinder folding unit with wire stapling device arranged to the side of it.

The endlessly printed paper web is folded lengthways by the funnel 1 and then cut into sheets. Then the sheets get their cross fold. The sheets 2 coming from the cross folder reach a folding table 3 and are stopped there by stops. Rotating folding knives 4, together with the folding rollers 5, 6, produce the longitudinal fold, whereupon the products folded to the size of the pages of the magazines come via the compartments 7 to the sheet exit. Here unstapled magazines are displayed (Fig. 1). J

During the production of stapled magazines, the folding knives 4 are stationary (Fig. 2). The sheets 2 coming from the transverse folding unit and stopped lying flat on the folding table 3 are withdrawn transversely to their previous running direction and laterally by the folding device

Folding table 3 arranged cylinder folder for the longitudinal fold passed with a wire stapler proven design is equipped. The transverse transport of the folded sheets 2 is carried out by rotating segment discs 8 actuated, which are arranged in the area of the folding table 3 and transversely to the path of the incoming sheet are. The segment disks 8 carry a snap strip 9 or the like, which interact with a conveying or nipping roller 10. The nipping roller 10 is through Springs pressed against stops in the direction of the segment disks 8. The segment discs 8 in Arches tapering in the axial direction are in the idle state by the segment discs and the nipping roller detected and transferred to the grippers 11 of the folding cylinder 12. The segment discs thus serve as sheet feeders for the folding cylinder 12. To prevent the sheets from fluttering, are above and below the arched track guide tongues 13, 14 are arranged.

The folding knife 15 of the folding cylinder 12 causes the jaw 16 of the jaw cylinder 17 to Fold the sheet lengthways. The sheets are stapled in front of this fold. So, as usual, wears the folding cylinder 12 stitching counterparts for the stitching heads of the adjacent stitching cylinder 18 of conventional design. Two stapling horns 19 serve to feed the stapling wire. The folded by the cylinder pair 12, 17 Sheets are lifted off the jaw cylinder by scrapers 20 and by endless conveyor belts 21 led out of the machine.

The stapler can also be switched off so that the cylinder folder 12, 17 can be used to

Claims (2)

PATENT CLAIMS: 1. Folding device for rotary printing machines, in which the - coming from the cross folder Sheet first stopped lying flat on a folding table and then one of the folding cylinders Longitudinal folding unit are fed, thereby indicates that in the area of the folding table rotating segment discs (8) the incoming Further convey folded sheets (2) transversely to their feed direction and one that works together with a wire stapler Hand over the folding cylinder (12). 2. Folding device according to claim 1, characterized in that the with a conveyor roller (10) cooperating segment discs (8) carry a common snap bar (9). 1 sheet of drawings
