Abstract
A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending along a length of the belt and a plurality of belt fibers transverse to the plurality of tension elements and interlaced therewith. The belt fibers define at least one traction surface of the belt. An edge fiber is located at a lateral end of the belt transverse to and secured to the plurality of belt fibers to secure the belt fibers in a selected position.
Claims9
A method of forming a belt for suspending and/or driving an elevator car, comprising:
- arranging a plurality of metallic tension elements along a length of the belt, defining a length of the belt;
- braiding a plurality of non-metallic belt fibers together with the plurality of tension elements to form a braided structure, the plurality of belt fibers extending transverse to the plurality of tension elements;
- braiding one or more non-metallic edge fibers into the plurality of belt fibers at a lateral side of the braided structure;
- and
- securing the one or more edge fibers to the plurality of belt fibers to retain the belt fibers in a selected position;
- wherein the one or more edge fibers include a thermally-activated material, which when set secures the one or more edge fibers to the plurality of belt fibers, the one or more edge fibers disposed parallel to the plurality of tension elements, the one or more non-metallic edge fibers mechanically closed around the plurality of belt fibers.
