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.

Abstract: Sorting and collating apparatus for use with copying and duplicating machinery for distribution of flexible sheet material to designated stations or series of stations. The device has an interface unit for accepting paper sheet copies and which selectively diverts said copies into a tray or to the base of the sorter tower. From the base the copies are either directed into the sorter tower to a designated bin or they are sent on to the next sorter tower module. The apparatus employs mass air movement type conveyors for paper transport. Means are provided for selectively diverting paper copies into designated paper receiving bins, and means may also be provided for maintaining the papers in aligned relationship in the individual paper receiving stations.
