Embodiment Construction

[0028] figure 1 and 2 A partial view of the printing press 1 is shown. This partial illustration shows the coating device 2 of the printing press 1 . The glazing device 2 comprises a counter cylinder 3 for conveying the printed sheets. Furthermore, the coating device 2 also includes a plate cylinder 4 , which cooperates directly with the counterpressure cylinder 3 .

[0029] The forme cylinder 4 is a so-called coating cylinder, which applies a varnish or similar coating liquid to the printed sheet. The plate cylinder 4 is equipped with a front holding device 5 and a rear holding device 6 . The front holding device 5 is used to fix the front end of a coating plate 18 which can be tensioned on the plate cylinder 4 in the direction of cylinder rotation, and the rear holding device 6 is used to hold the rear end of the plate. The holding devices 5 , 6 are clamping devices in which the edge of the plate is clamped. Glazing plate 17 can be flexographic printing plate, also can...

Abstract

The invention relates to an printing press (1), which includes an apparatus for handling or manipulating varnishing plates or printing plates, having a plate feed channel (10) which is at least temporarily disposed in a plate feed position (22) for feeding a varnishing or printing plate (17) out of the plate feed channel (10) to a plate cylinder (4). A seat or step surface (9) for an operator is disposed above the plate feed channel (10).

Description

technical field [0001] The invention relates to a printing press comprising a device for handling coating or printing plates having a plate feed channel at least temporarily in a plate feed position for feeding from the plate feed channel to a plate cylinder Provide glazing plate or printing plate. Background technique [0002] A device for automatically changing printing plates is described in DE 4322027 A1. The device is preferably used in small format web rotary presses. The device comprises a plate feeder which is pivotable into a position in which the plate feeder is oriented substantially horizontally. This unit is not suitable for use on sheet-fed presses. Sheet-fed printing presses usually have a coating unit whose coating plates are changed manually. In practice, the operator stands next to the coater when changing plates, but this is not an ergonomic advantage. The replacement of the large-format version is particularly uncomfortable. Two operators are requir...
