Abstract
Two belt type singulators are used in apparatus which feeds and singulates stacked articles which have varying thickness and shape. The singulators form tandem, spaced apart singulator nips with a transport belt. Each singulator belt has a downwardly sloped underside and moves incrementally around its rollers over time, overcoming certain applied resistive forces. The singulator belt has intermittent contact with the transport belt, when articles are being processed, and there is a resultant scuffing of belts which helps remove debris. Preferably, on off the forces which resists singulator belt motion is created by having a singulator pair with upper rollers, which are rotationally coupled but which have different diameters. The upper ends of the singulator belts project into the hopper which holds the stack and aid in the feeding of articles toward the singulating nips.
