Abstract
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.
