METHOD AND APPARATUS FOR MANUFACTURE OF ELONGATED RUBBER CABLE ARTICLE FOR MINING EQUIPMENT Russian patent published in 2005 - IPC

FIELD: method and equipment for manufacture of conveyor belts used in mining industry.

SUBSTANCE: method involves feeding, directing and pulling cables through system of mechanisms; stretching and facing cables with rubber; curing rubber and winding ready product. Torque is preliminarily set for each cable and torque of each cable is measured before facing it with rubber. In case measured torque of cable differs from set value, said torque value is regulated until set value is reached. Apparatus has feeding mechanism and directing mechanism mounted in the course of process and including carrier support accommodating frames with spools for receiving of cables, retaining mechanism, cable stretching mechanism, mechanism for facing of cables with rubber, rubber curing mechanism, ready product winding mechanism and controlling and measuring device adapted for controlling of process and arranged between cable stretching mechanism and mechanism for facing of cables with rubber. Each frame with spool for receiving of cable is installed on carrier support for rotation around its axis.

EFFECT: increased efficiency and improved quality of ready product.
