Embodiment Construction

[0028] figure 1 A machine 1 for processing sheet-fed printing materials 2 is shown. The machine 1 is a rotary printing press for lithographic offset printing and comprises sheet-fed transport devices, which are a transfer cylinder 3 , an impression cylinder 4 and a chain conveyor 5 . These sheet-sheet transport devices each comprise a bridge-shaped gripper system 6 .

[0029] figure 2 Representation: Each gripper system 6 comprises a gripper holder 7 and a single-sheet gripper 8 pivotable relative to the gripper holder, which are arranged in a row. The gripper system 6 is used to grip the leading edge of the current sheet-fed printing material 2 .

[0030] image 3 Representation: Each sheet-fed gripper 8 has a gripper core 9 and a shell 10 covering the gripper core 9 .

[0031] Gripper core 9 is made of a metal as base material 11 . The housing 10 consists of a clamping surface material 12 , that is to say the material which forms the clamping surface 13 of the sheet-f...

Abstract

The invention relates to a gripper of single paper, wherein the single paper gripper (8) comprises a base (11) with stable shape and an elastic clamp face (12) which are connected via matched shapes.

Description

technical field [0001] The invention relates to a sheet-fed gripper for gripping a sheet-fed printing material, in which a dimensionally stable base material is connected to an elastic clamping surface material forming a clamping surface. [0002] The invention also relates to a gripper system with a single-sheet gripper and a gripper support cooperating with the single-sheet gripper. [0003] The invention also relates to a machine for processing sheet-fed printing materials, which comprises a sheet-fed transport device with a gripper system. [0004] The invention also relates to a method for producing a sheet-fed gripper, in which a dimensionally stable base material is connected to an elastic clamping surface material, Background technique [0005] Such a sheet-fed gripper is described in DE 31 46 836 A1. In this prior art sheet-fed gripper, the material of the clamping surface peels off from the base material over time. Detached gripping face material can become stra...
