ABSTRACT:
A continuous apron type sortation conveyor having carton pushers which travel with and crosswise of the apron is provided with branch lines arranged in pairs directly opposite each other along the main line. A pair of oppositely angled guide tracks for the pushers is positioned between each opposed pair of branch lines, but these tracks are interrupted at their crossing point to provide a gap, and a switching assembly in this gap is movable between aternative positions wherein it fills the interruption in one or the other track to enable pusher elements to travel across from either side of the apron as desired to deliver a carton to one or the other of an opposed pair of branch lines.
