Abstract
A dual entry-double helix spiral delivery chute is provided which includes two spiral delivery chutes nested one above the other and being aligned with the same vertical axis. The two chutes are substantially identical in that they provide the same footprint as a single chute. Each chute, moreover, in addition to having an output port includes a top entry port and a side entry port downstream of the top entry port so that each chute can be served by two or more separate sorting machines receiving items from one or more separate sources.
