Abstract

A conveyor apparatus for diverting product from a single lane to one of a plurality of lanes includes a wall having an upstream portion positioned proximate the single lane and a downstream portion positioned proximate the plurality of lanes. The upstream portion is stationary relative to the single lane and the downstream portion is configured to be movable relative to the plurality of lanes. A length of the wall is configured to vary in response to movement of the downstream portion.
