Embodiment Construction

[0031] A machine for processing individual sheets 7 , for example a printing press 1 , has a feeder 2 , at least one printing unit 3 or 4 and a delivery 6 . The individual sheets 7 are removed from an individual sheet stack 8 and separated or transported in scales via an infeed table 9 to the printing units 3 and 4 . These printing units each comprise a printing form cylinder 11 , 12 in a known manner. The printing form cylinders 11 and 12 each have a device 13 , 14 for fixing a flexible printing form. Furthermore, a device 16 , 17 for semi-automatic or fully automatic changing of printing plates is assigned to each printing plate cylinder 11 , 12 .

[0032] The sheet stack 8 rests on a stacking pallet 10 which can be raised in a controlled manner. The sheet 7 is removed from the upper side of the sheet stack 8 by means of a so-called suction head 18, which mainly has a plurality of lifting and pulling suction devices 19, 21 for separating the sheets 7. . Furthermore, a bl...

Abstract

An apparatus for forming stacks in sheet-processing machines, in particular printing machines, includes side stops moving back and forth. The stops are divided into upper and lower parts. The lower part can be displaced vertically or in slotted guides and can interact with a switch in order to switch off a stack lift drive.

Description

technical field [0001] The invention relates to a stop for the side of a stack of individual sheets. [0002] The invention also relates to a delivery for a sheet-fed rotary printing machine. Background technique [0003] In machines for processing sheets, it is considered that there are stops which interact with the sides of a stack of sheets. In particular for forming the individual sheet stacks, they can be driven reciprocatingly at the cycle time of the individual sheet processing machine, wherein they act on the side of the stack which is oriented laterally in the direction of transport of the individual sheets. [0004] Such a device is known from DE 43 22 561 C2. It shows a run-in device of the aforementioned type, which is mounted so that it can be tilted at a small angle in the side support of the delivery of a sheet-fed printing press. The tilting movement can be detected by a switch and leads to a shutdown of a stack lift. [0005] In order to adjust these sto...
