CURVE CONVEYOR BELT

摘要

A connection line for a belt portion held between a driving roller (41) and a pinch roller (42a) and for a region extending from the vicinity of the belt portion to the outer peripheral edge is a single straight line or a gentle curve having a large angle with respect to a tangent to the peripheral line of a belt. The connection for the outer belt portion is by means of a finger joint. Further, the connection for the belt portion held between the driving roller (41) and the pinch roller (42a) and for the region extending from the belt portion to the outer peripheral edge is by means of a finger joint using fingers installed with a large pitch, and the connection for the other belt portion is by means of a finger joint using fingers installed with a small pitch. Thus, it is possible to provide a curve conveyor belt with no peeling or break occurring in the joint portion for a long time, the thickness of the joint portion not becoming large, and at low cost.
