Abstract:
A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.
