Reinforced fabric elevator belt with improved internal wear resistance
A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending longitudinally along a length of the belt, at least one tension element of the plurality of tension elements having one or more tension element coating layers applied thereto. A plurality of fibers are interlaced with the plurality of tension elements forming a composite belt structure. A belt coating at least partially encapsulates the composite belt structure. A method of forming a belt for suspending and/or driving an elevator car includes forming a plurality of tension elements and applying one or more coating layers to at least one tension element of the plurality of tension elements. A plurality of fibers are interlaced with the plurality of tension elements to form a composite belt structure. A belt coating is applied to the composite belt structure to at least partially encapsulate the composite belt structure.
1 . A method of forming a belt for suspending and/or driving an elevator car comprising:
forming a plurality of tension elements;
applying one or more coating layers to at least one tension element of the plurality of tension elements, the one or more coating layers including a fiber material;
interlacing a plurality of fibers with the plurality of tension elements to form a composite belt structure;
applying a belt coating to at least partially encapsulate the composite belt structure;
wherein the fiber material includes one or more of aramid, polyester, nylon, polyphenylene sulfide, cotton, jute, hemp, or any combination or blends thereof;
wherein the one or more coating layers are applied to the at least one tension element prior to the interlacing of the plurality of fibers with the plurality of tension elements.
2 . The method of claim 1 , further comprising forming each tension element of the plurality of tension elements from a plurality of wires.
3 . The method of claim 1 , further comprising applying the one or more coating layers to the plurality of tension elements via an extrusion, dip, spray, evaporation, roll-on, or thermal fusion process.
4 . The method of claim 1 , further comprising applying a first coating layer to the plurality of tension elements to promote adhesion to the plurality of tension members.
5 . The method of claim 4 , further comprising applying a second coating layer to the plurality of tension elements to promote adhesion of the belt coating.
6 . The method of claim 1 , further comprising heating the one or more coating layers to adhere the one or more coating layers to the tension elements.
