Abstract

An illustrative example method of making an elongated load bearing member includes providing a plurality of tension elements. A plurality of weave fibers are woven together with the tension elements to thereby establish a weave. A traction surface is established on at least one side of the load bearing member. The traction surface is defined by the weave fibers. Coating the weave fibers with a compressible coating provides an exterior surface texture defined at least in part by the weave fibers.

First claim

We claim:

1 . A method of making an elongated elevator load bearing member for a traction elevator system, comprising the steps of:
providing a plurality of tension elements; weaving a plurality of weave fibers together with the tension elements; and establishing a traction surface on at least one side of the load bearing member, the traction surface being defined by the weave fibers; and coating the weave fibers with a compressible coating, the coating having an exterior surface texture defined at least in part by the weave fibers.

2 . The method of claim 1 , comprising applying the coating to at least the weave fibers subsequent to weaving the weave fibers and the tension elements together.

3 . The method of claim 1 , comprising establishing a spacing between the tension elements and the traction surface using the weave fibers.

4 . The method of claim 3 , comprising arranging the weaver fibers in a pattern that that prevents the tension elements from contacting a component that the traction surface engages.

5 . The method of claim 1 , comprising including elastomer material fibers in the weave fibers.

6 . The method of claim 1 , comprising
arranging some of the weave fibers generally parallel to each other; arranging some of the weave fibers at a first angle; arranging others of the weave fibers generally parallel to each other; and arranging the others of the weave fibers at a second, different angle.

7 . The method of claim 1 , wherein the tension elements comprise a first material and the weave fibers comprise a second, different material.

8 . The method of claim 1 , wherein the coating comprises at least one of urethane and thermoplastic polyurethane.

9 . The method of claim 1 , wherein the coating comprises an elastomer.
