ABSTRACT:
Suction feet are arranged to pick up and feed a sheet from a stack and a blower is arranged to blow air against the edges of the sheets on the stack to separate the top sheet from the rest. A cam assembly driven through a novel one-rotation clutch moves a piston in a cylinder which is connected to both the feet and blower so that the piston is moved in one direction to supply pressurized air to the blower and subsequently in the opposite direction to apply suction to the suction feet. A cylindrical presser member is carried by each suction foot which extends past the suction foot to bend the top sheet during pickup and further aid in separating the top sheet from the lower sheets.
