ABSTRACT:
A conveyor belt having a direction of travel includes a plurality of pivotal transverse rods extending laterally across the belt and having inner and outer ends along inner and outer edges of the belt and a plurality of connecting links disposed in a pair of spaced rows at the inner and outer ends of the rods. Each of the connecting links has a base portion and a pair of spaced legs rigidly connected to the outer ends of the base portion and each of the legs has at least one stepped portion parallel to the direction of travel. The stepped portions on opposing legs are spaced apart a relatively narrow distance at the base portion and a relatively wide distance at the opposite end thereof. The stepped portions include a substantially straight segment at the narrower stepped portion, a substantially straight segment at said wider stepped portion, and an angled segment therebetween connecting the substantially straight segments. The angled segment between the substantially straight segments of the stepped portion of the inner connecting links is greater in length than the angled segment between the substantially straight segments of the stepped portion of the outer connecting links. The shorter length of the outer angled segments maintains the direction of travel of the belt in a normal straight orientation by limiting the amount of lateral clearance between adjoining connecting links and the longer length of the inner angled segments allow adjoining inner links to fully collapse in an alternate orientation to follow paths curved laterally to one side.
