Duplicating systems with sheet handling features
US 3894733 A
Abstract
An improved reproduction system for making duplicates from an original having a printing cylinder provided with a clamp for selectively receiving, holding or ejecting a master, a take-up assembly adapted to cooperate with an eject mode of cylinder clamp operation to receive a discharged master, an original and master material feeding assembly adapted to bring the original and master into registry and carry the sandwiched original and master material into an imaging assembly to make a duplicating master, a transfer assembly adapted to transfer the imaged master toward the cylinder clamp, and the latter operating in a receiving mode adapted to draw the master to the printing cylinder, and to hold the imaged master during a print mode of cylinder operation in which reproductions are made. The system has controls for programming the machine through respective preparation, function and print cycles.
