ABSTRACT:
A separator for separating adjacent transparencies in a stack of transparencies, where the separator is characterized by enhanced permeability due either to the intrinsic material from which it is made, or due to a plurality of apertures, holes, perforations or the like provided through its surface. In use, the separator adheres to the transparency due to suction created by a vacuum transport mechanism of the reproduction machine such that the transparency and separator move as a unit along a paper path of a reproduction machine.
