摘要： A feed and takeoff assembly particularly adapted for use in connection with a printing press to automatically transfer generally flat stock from a first position to a print position and to a delivery position, having a frame, a transfer carriage mounted for movement along the frame, a single elongated feed gripper mounted near one end of the transfer carriage and disposed transversely to the path of travel of the carriage along the frame, and a delivery gripper mounted near the opposite end of the transfer carriage for movement therewith along the frame. The single elongated feed gripper is maintained in constant registered position during movement along the frame by a spring-biased cam-operated guide means. The delivery gripper acts to remove an entire sheet of printed stock at a desired time by a cam-operated opening and closing of upper and lower jaws mounted on a common pivot print. The operation of the transfer carriage and associated feed gripper and delivery gripper relative to the operation of the printing press is timed by a plurality of control cams which provide for feeding and delivery of stock and return of the carriage at optimum speeds without errors in registration.
