ABSTRACT:
An array of low friction impact slides for supporting a moving conveyor belt beneath a generally crescent-shaped section of the belt opening outwardly to one side thereof and beneath portions of the belt disposed proximate to but beyond the distal ends of this section. Except for the slides, which have smooth, generally planar upper surfaces across the belt can be pulled, the crescent-shaped section is virtually unsupported. Both upstream and downstream of the crescent-shaped section, pairs of idlers slope downwardly toward each other. Where the belt is supported by two such pairs of idlers which are contiguous to each other, it assumes a trough-like configuration. Proximate the crescent-shaped section, on the other hand, the idlers are unpaired and disposed horizontally. These unpaired idlers are largely, if not entirely, disposed beneath the same side of this section. When force is applied which causes a sufficiently large, heavy object to move transversely across the crescent-shaped section, the weight of the object causes the belt to assume a shape determined by the upper surface of the slides. These upper surfaces are so oriented generally that the crescent-shaped section, when weighted, takes on the shape of a channel which feeds the oversized object toward the edge of the belt.
