Embodiment Construction

[0022] A machine for processing 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 sheets 7 are removed from the stack 8 and transported individually or in sheets via a transport table 9 to the printing unit 3 or 4 . These printing units each contain a printing form cylinder 11 , 12 in a known manner. The printing plate cylinders 11 and 12 each have a device 13 , 14 for fixing a flexographic printing plate. Furthermore, a device 16 , 17 for semi-automatic or fully automatic changing of printing plates is assigned to each printing plate cylinder 11 , 12 .

[0023] The paper stack 8 rests on a stacking plate 10 which can be raised in a controlled manner. The sheets 7 are removed from the top side of the stack 8 by a so-called suction head 18 which also has lift and drag nozzles 19 , 21 for separating the sheets 7 into individual sheets. Furthermore, a blower device 22 for loosening the upper sheet layer and a ...

Abstract

The invention relates to an apparatus for releasing paper in the paper transmitting route to an auxiliary pile behind the main paper pile, in which a paper guide plane is provided with a paper releasing opening which is closed by a paper combing element and a valve under closing state. The combing element and the valve is used as guiding element when the paper is released.

Description

technical field [0001] The invention relates to a device for releasing a sheet from a sheet transport path, and more particularly to depositing the sheet on an auxiliary delivery pile arranged in front of the main delivery pile. Background technique [0002] DE 198 19 491 C1 discloses an auxiliary delivery pile for collecting waste sheets which is located ahead of the main delivery pile in the direction of sheet transport. In order to release the sheets onto the scrap pile, rollers with grippers are provided. The roller receives sheets from the sheet transport system and transfers them to the waste sheet pile at machine speed. The placement speed is so high that good sheet stacking cannot be achieved. Contents of the invention [0003] The object of the present invention is to provide a device for releasing sheets onto an auxiliary delivery pile for further processing. [0004] According to the invention, a device for releasing sheets from a sheet transport path is prop...
