摘要

A manufacturing method of a finite conveyor belt of the present invention includes a laminated body formation step of forming a laminated body (35) in which a core layer member (32) which includes a tensile body (14) is interposed between an unvulcanized top cover rubber member (33) and an unvulcanized bottom cover rubber member (34) in a belt thickness direction T, and a vulcanization step of vulcanizing the laminated body (35) by pressurizing in the belt thickness direction (T) and heating the laminated body to form a finite conveyor belt, and the laminated body formation step includes a member formation step of forming the top cover rubber member (33) by separately connecting both ends of an unvulcanized first cover rubber part (36) in a belt length direction (L) in which a detection object (15) is embedded with ends of an unvulcanized second cover rubber parts (37) in the belt length direction (L).

主权项

1. A manufacturing method of a finite conveyor belt in which, in a finite top cover rubber part in which a tensile body is embedded, a detection object which is abraded according to an amount of abrasion of a surface of the finite top cover rubber part is embedded in a portion positioned on the top surface side rather than on the tensile body side, the method comprising:
a laminated body formation step of forming a laminated body in which a core layer member which includes the tensile body is interposed between an unvulcanized top cover rubber member and an unvulcanized bottom cover rubber member in a belt thickness direction; and a vulcanization step of vulcanizing the laminated body by pressuring in the belt thickness direction and heating the laminated body to form the finite conveyor belt, wherein the laminated body formation step includes a member formation step of forming the top cover rubber member by separately connecting both ends of an unvulcanized first cover rubber part in a belt length direction in which the detection object is embedded with ends of unvulcanized second cover rubber parts in the belt length direction.
