Abstract
Abstract A photocopy machine in which a web of photocopy paper is fed from a supply roll and in which a length setting mechanism, manually settable to the length of the original document on a moving table, upon movement of the table, operates an oscillatory cutting mechanism to produce a copy sheet of the same length as the original document without affecting the speed of movement of the copy sheet through the machine.
