  • Patent number: 4955466
    Abstract: The radially outermost marginal portion of a flat washer-like or disc-shaped belt in a belt conveyor is confined in an arcuate slot of a reinforcing member which has (a) a bead surrounding the peripheral surface of the marginal portion, and (b) two lips each of which extends radially inwardly of the bead and overlies one of the two lateral surfaces of the marginal portion. The lips are fastened to the belt, and the bead has a convex external surface which is guided by pairs of rolling elements at locations radially outwardly of fasteners which secure the lips to the belt. This reduces the likelihood of spreading of the open inner end of the slot and resulting rapid destruction of the reinforcing member.
