Title:
METHOD FOR MANUFACTURING CONVEYOR BELT WITH ENDS, METHOD FOR SPLICING CONVEYOR BELTS WITH ENDS, METHOD FOR MANUFACTURING ENDLESS CONVEYOR BELT AND CONVEYOR BELT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/132743
Kind Code:
A1
Abstract:
This method for manufacturing conveyor belts with ends comprises: a laminate-forming process for forming a laminate (35) in which a core layer member (32) provided with a tensile body (14) is interposed between an unvulcanized front surface rubber cover member (33) and an unvulcanized back surface rubber cover member (34) in the belt thickness direction (T); and a vulcanizing process for vulcanizing the laminate (35) by applying pressure and heating same in the belt thickness direction (T) to form conveyor belts with ends. The laminate-forming process comprises a member-forming process for forming the front surface rubber cover member (33) by connecting an end, in the longitudinal direction (L) of the belt, of an unvulcanized second rubber cover (37) on each of the two ends, in the longitudinal direction (L) of the belt, of an unvulcanized first rubber cover (36). A detection object (15) is embedded in the first rubber cover.
