Abstract (en)
[origin: US4592279A] A sheet gripper for the delivery system of a printing machine or the like includes a clamp member adapted to be secured on a pivotable gripper shaft, and a gripper finger mounted resiliently on the clamp member and adapted to be brought into contact with a sheet to be gripped during pivoting of the gripper shaft. The clamp member is made of two sheet-metal parts and includes a base member and a bottom part, which are adapted to be hooked into engagement with one another on one side of the shaft and connected together by a mounting screw on the other side of the shaft to secure the clamp member on the gripper shaft. The gripper finger is also secured on the base member at one end by means of the mounting screw and is adjustable by means of a set screw threadably received in the base member approximately at the other end thereof. The gripper finger is made of spring steel and is pre-stressed to a specific spring force by means of a dimensioned recess and has a guide slot formed therein in which a lug formed on the base member is disposed to guide the gripper finger relative to the base member.
