Abstract

An adjusting device for a gripper opening cam in a chain delivery of a sheet-fed printing press, the gripper opening cam being pivotally guided in a bearing and being connected by a linkage to one of a pair of threaded nuts of a combination of a lefthand and righthand thread of an adjusting shaft screwable into a fixedly supported other threaded nut of the combination, includes an adjusting motor with an electrical program controller programmable for adapting to parameters which vary as the printing press rpm runs up to and runs down from operating speed for automatically tracking the gripper opening cam, and a coupling operative in the adjusting device, the coupling being disposed between the adjusting motor and the gripper opening cam.
