Abstract
A slip roller conveyor has a frame comprising a pair of parallel, spaced-apart side plates. Secured to each of the side plates is a plurality of annular rollers with a predetermined pitch distance between adjacent rollers. The annular rollers have tubular sleeves of a lesser diameter projecting outward from a side surface thereof. The tubular sleeves on an opposed pair of annular rollers fit into the lumen of a longer tubular roller with a clearance fit. The annular rollers on each of the side plates are driven by an endless belt that also surrounds a motor-driven nose roller.
