Embodiment Construction

[0018] figure 1 A representative example of an apparatus for trimming products on three sides is shown. The first drive motor 1 moves the tool movement device 2 on which the tool 3 is fastened. The direction of product movement is indicated by arrows. The second drive motor 4 drives the conveyor belts 7 , 8 of the conveyor device 9 via the first and the second drive shaft 5 , 6 . Control units 10 , 11 are provided for the two drive motors 1 , 4 , which can communicate with each other via a data and / or control signal exchange link 12 . Furthermore, the connection 12 also leads to a machine control unit and to an alignment control mechanism 42 of the alignment device 30 .

[0019] figure 2 The delivery device itself is shown. The drive motor 4 drives the drive shafts 5 , 6 and the conveyor belts 7 , 8 of the conveyor system by means of a mechanical transmission 14 . Furthermore, a control unit 11 and a data and / or control signal exchange connection 12 can be seen. Produc...

Abstract

The apparatus (50) has a controller for initiating and / or ending pushing movement of an alignment device such that the timing of initiating and or burst duration of the pushing movement within cycle time is independent of lifting movement of a blade lifting device (2). The alignment device includes an impact bar, which is mounted on a holder and guide rods in a knife block. The knife block includes a threaded spindle with a spindle nut. The holder is connected to the spindle nut. The threaded spindle is connected with a drive, which includes a motor and a toothed belt drive.

Description

technical field [0001] The invention relates to a device for three-sided trimmed products, in particular paperback books, according to the preamble of claim 1 . Background technique [0002] When producing paperback books, the collated and bound product is cut in a device for three-sided cutting, for example a three-sided cutter. This is done in the cutting station for cutting the leading edge and cutting the top or footing by means of a movable upper blade towards a stationary lower blade. The cutting of the paperback book is a particularly important step here, since the folded sheets are thus opened laterally and significantly affect the appearance of the paperback book. Therefore, the precise positioning and cutting of paperback books is particularly important. The specific positioning of the paperbacks is ensured on the one hand by the three-sided cutter feed. On the other hand, in order to precisely adjust the cut-off width for top-cut or foot-cut cuts, the product i...
