Abstract
Gripper control device in a chain delivery of a sheet-fed printing press, wherein a cam segment has a control cam for a control roller provided on a gripper system and is adjustably disposed for opening a gripper of the gripper system as a sheet is delivered, the control cam being formed with a rectilinear on-running region aligned for rectilinear movement of the control roller in a given direction, includes an adjusting element operatively engageable with the cam segment for effecting a phase displacement of the gripper between a closed and an open condition thereof, the control cam of the cam segment, in an inactive basic position thereof, being aligned, with the on-running region thereof parallel to the given direction of rectilinear movement of the control roller for the gripper system, in an imaginary plane tangent to the control roller at a location on the circumference thereof most distal from the gripper of the gripper system, and a cam roller rotatably mounted on the cam segment, the adjusting element having a rotatably mounted control cam in operative engagement with the rotatably mounted cam roller.
