ABSTRACT:
A positive displacement sorter apparatus includes a plurality of interconnected slats defining an endless web, an upper run of the endless web defining a conveying surface. A plurality of pusher shoes are provided, each moving along at least one of the plurality of slats to laterally displace articles on the conveying surface. A linear motor propulsion system may be provided for propelling the web including at least one motor primary and a plurality of motor secondaries at the slats.
