  • Sheet feeding and separating apparatus with an improved entrance guide
    Patent number: 5192068
    Abstract: A sheet feeding and separating apparatus includes a multiple piece entrance guide located between a stack from which sheets are to be fed and a retard nip. The guide includes a polycarbonate base member, a radiused high friction urethane retard member and a flexible polycarbonate or polyester film deflector member. The urethane is ground to a radius on the leading edge to promote the feeding of down curled sheets, shingling of sheets and the breaking up of slugs prior to entering the retard nip. The deflector member assists in feeding down curled sheets.
