摘要： A belt for yarn twisting that exhibits a prolonged belt life and is capable of attaining a stabilization of yarn quality. There is provided an endless belt comprising surface rubber layer (1) brought into contact with yarns to be twisted and hung and, superimposed on the surface rubber layer (1), reinforcing layer (2), the reinforcing layer (2) on its side of surface rubber layer (1) furnished with middle woven fabric (3), wherein a seamless woven fabric is used as the middle woven fabric (3). The seamless woven fabric is stretchable in the direction of belt circumference and is rigid in the direction of belt width. The reinforcing layer (2) is composed of the above middle woven fabric (3) consisting of the seamless woven fabric, interlining layer (4) having core yarns buried in the direction of belt length, and outer surface woven fabric (5) brought into contact with a pulley. The reinforcing layer (2) is integrated with the surface rubber layer.

摘要： Elevator drive belts (5) driving an elevator rope (3) connecting the car (1) of an elevator to a counterweight (2) while applying a frictional force thereto, wherein the rubber hardness of the belts is set to approx. 50 to 90°to suppress a creep slip due to a shearing strain during the operation of the elevator, whereby even if the frictional force applied to the elevator rope (3) is reduced due to a reduction in the weight of the elevator caused by a reduction in the weight of the car (1) and the counterweight (2), the drive force of the elevator can be guaranteed by the frictional force applied from the elevator drive belts (5) to the elevator rope (3).
