Abstract
A method of making an elevator load bearing member includes unidirectional weaving a plurality of load bearing fibers including at least a first material and a second material. A melting point of the first material is higher than a melting point of the second material. The method includes bonding the load bearing fibers together by at least partially melting at least some of the second material and coating the plurality of load bearing fibers.
Claims18
A method of making an elevator load bearing member, the method comprising:
- unidirectional weaving a plurality of load bearing fibers including at least a first material and a second material, wherein at least some of the load bearing fibers comprise the first material and the second material, and wherein a melting point of the first material is higher than a melting point of the second material;
- bonding the load bearing fibers together by at least partially melting at least some of the second material;
- and
- coating the plurality of load bearing fibers.

A method of making an elevator load bearing member, the method comprising:
- unidirectional weaving a sheet of a plurality of load bearing fibers including at least a first material and a second material, wherein at least some of the load bearing fibers comprise the first material and the second material, and the first material having a melting point that is higher than a melting point of the second material,
- bonding the plurality of load bearing fibers together by at least partially melting at least some of the second material;
- and
- coating the plurality of load bearing fibers to provide a coating, wherein the coating has a rectangular cross section defining a width of the elevator load bearing member, wherein the sheet of the plurality of load bearing fibers is continuous and extends across a majority of the width.
