Abstract
A positive displacement sorter apparatus includes a plurality of interconnected slats defining an endless traveling web. An upper run of the web defines a first conveying surface traveling in a longitudinal direction. A plurality of pusher shoes are provided, each moving along at least one of the slats to laterally displace an article on said conveying surface. A web end portion of the web is extendable and contractible in the longitudinal direction. A product handling conveyor at the web end portion has a second conveying surface that is adapted to supply product to, or receive product from, the first conveying surface. The product handling conveyor has a conveyor end portion that is adjacent to the web and is moveable with extension and contraction of the web end portion. In this manner, the first and second conveying surfaces maintain a constant relative relationship.
