ABSTRACT:
Paper handling equipment is disclosed having a cart and a paper feeder. The paper feeder has an elevator and a paper feed train. The cart allows rolling transfer of a stack of paper sheets from the cart to the elevator in the paper feeder. The elevator positions the stack of paper sheets with respect to a desired elevation of the top sheet in the stack. The paper feed train removes the top sheet from the stack of paper in the elevator by using a rotating high-vacuum wheel. Included is a marker sheet detection means for detecting specially prepared marker sheets. A doubles detector is used to eliminate double sheets which are inadvertently fed into the paper feed train. A counting means is used to count the number of single sheets fed. A control means is used to automatically feed a preprogrammed number of sheets from a number of different types of paper separated by marker sheets. Excess copies of paper sheets of any particular type are rejected into a rejection tray. Vacuum transport conveyor belts are used to feed the paper sheets to other paper handling equipment.
