Title: Flexible conveyor belt and belt conveyor
Inventor: LENNART TINGSKOG
IPC: B65G15/02
Filed: 1990-06-18
Granted: 1995-01-20
Abstract: PCT No. PCT/SE88/00626 Sec. 371 Date Aug. 15, 1990 Sec. 102(e) Date Aug. 15, 1990 PCT Filed Nov. 18, 1988 PCT Pub. No. WO89/05765 PCT Pub. Date Jun. 29, 1989.A conveyor belt of elastic material comprises a planar central part, two planar edge parts, and two hinge parts. The central part is flexurally rigid about the longitudinal axis of the belt by virtue of a first and a second transverse reinforcement layer and has a low extensibility in the longitudinal direction by a longitudinal reinforcement. One of the two planar edge parts is hingedly connected with each side edge of the central part. Both edge parts are flexurally rigid about the longitudinal axis of the belt by virtue of the first and a third and a fourth transverse reinforcement layers, and are further extensible in the longitudinal direction of the belt and have a total width which is at least equal to the width of the central part. One of two hinge parts interconnect an edge part with the central part. The hinge parts are flexible about the longitudinal axis of the belt and extensible in the longitudinal direction of the belt. The hinge parts are further resilient for pivoting the edge parts out from a position folded towards the central part, and have a substantially smaller width than the central part. The belt conveyor assembly, in which the conveyor belt is included, comprises support rollers for supporting the belt, and guides for maintaining the desired shape of the belt. The guides comprise pressing elements which, against the spring action of the hinge parts, hold the edge parts in the desired position relative to the central part.
