摘要： An endless flat belt includes an inner rubber layer 1, a cord core 11 buried in the inner rubber layer 1 and spirally wound at a predetermined pitch in a width direction of the belt, and a reinforcement fabric 2 stuck to the inner rubber layer 1. The cord core comprises polyamide fiber. Opposite ends of the reinforcement fabric 2 are connected with each other into an endless form by adhesion or sewing. A surface rubber layer 3 is stuck to a surface of the reinforcement fabric 2 which is opposite a surface thereof stuck to the inner rubber layer 1.

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).

摘要： A flat belt 20 is prepared. A first belt end 21 of the belt 20 has a finger shape and a second belt end 22 of the belt 20 has the complimentary shape to the first belt end 21. An adhesive is applied to one of an end face 21K of the first belt end 21 and an end face 22K of the second belt end 22 or to both. Next, both end faces 21K and 22K are butted. The butted portion B of the first and second belt ends 21 and 22 are pressed in the belt width direction. Due to this, the end faces 21K and 22K are bonded by the adhesive so that the first and second belt ends 21 and 22 become joined.
