BELT CONVEYOR

摘要

A belt conveyor comprises a frame wherein at least two support rolls for supporting a laterally curved endless conveyor belt are disposed. The laterally curved endless conveyor belt carries on at least one of its surfaces a guiding bead disposed at or adjacent the outer peripheral edge thereof. Furthermore the belt conveyor comprises one or more bearing rolls (44) for bearing the guiding bead. The guiding bead is a coextruded layered bead comprising a base layer of a base layer material which is fastened to the conveyor belt and a top layer of a top layer material which is flexible and wear resistant. Preferably the base layer is thermoplastically bonded to a top cover of the conveyor belt. If necessary the base layer is melted into a supporting bottom fabric of the conveyor belt. The top layer material comprises preferably a thermoplastic rubber or copolymer.
