ABSTRACT:
An axially shiftable sheet gripper assembly includes cooperating gripper fingers and gripper abutment surfaces mounted on an axially slidable carriage. The carriage is located in a groove in a sheet transfer drum and carries a control roller at one end. The control roller rides on a control surface of a pivotable control disk. This control disk is movable toward and away from a side face of the sheet transfer drum to regulate the axial movement of the sheet transfer mechanism carriage.
