Abstract
A device for adjusting the release point of the timing of a gripper release in a sheet delivery of a sheet-processing machine, such as a printing machine, is disclosed. A gripper system is driven along a given travel path. The gripper system has gripper fingers for clamping a paper sheet, entraining the paper sheet along the given travel path and releasing the paper sheet at a predetermined position. A landing body with a cam surface is disposed at a stationary support structure and it is operatively associated with a member for releasing the paper sheet which travels with the grippers. The landing body is shiftable on a displacement track for the purpose of adjusting the timing of the paper release. The displacement track has a shape which is adapted to a geometric course of the given travel path of the gripper system.
