Abstract
A belt for an elevator system includes a plurality of tension members arranged along a belt width, a jacket material at least partially encapsulating the plurality of tension members defining a traction surface, a back surface opposite the traction surface together with the traction surface defining a belt thickness, and two end surfaces extending between the traction surface and the back surface defining the belt width. A metallic coating layer applied from a liquid solution is positioned over at least one end surface of the two end surfaces.

A method for forming a belt for an elevator system comprising:
- forming one or more tension elements configured to extend along a belt length;
- at least partially enclosing the one or more tension elements in a jacket material, the jacket material defining:
- a traction surface;
- a back surface opposite the traction surface together with the traction surface defining a belt thickness;
- and
- two end surfaces extending between the traction surface and the back surface defining the belt width;
- and
- applying a metallic coating layer to at least one end surface of the two end surfaces from a liquid solution to improve fire retardation properties of the belt;
- wherein the metallic coating layer is applied discontinuously along the belt length, defining a plurality of coating blocks and a plurality of coating gaps arranged in an alternating pattern along the belt length.
A belt for an elevator system comprising:
- a plurality of tension members arranged along a belt width and extending longitudinally along a belt length;
- a jacket material at least partially encapsulating the plurality of tension members defining:
- a traction surface;
- a back surface opposite the traction surface together with the traction surface defining a belt thickness;
- and
- two end surfaces extending between the traction surface and the back surface defining the belt width;
- and
- a metallic coating layer applied from a liquid solution disposed over at least one end surface of the two end surfaces;
- wherein the metallic coating layer is discontinuous along the belt length, defining a plurality of coating blocks and a plurality of coating gaps arranged in an alternating pattern along the belt length.
