ABSTRACT:
A method of making a load bearing member (30) for an elevator system (20) includes placing at least one tension member (32) adjacent one side (60) of a first layer (36) of a polymer material. A second layer (38), comprising a urethane in a disclosed example, is added adjacent to at least the one side (60) of the first layer (36) such that the tension member (32) is between the first layer (36) and the second layer (38). Such a technique allows for eliminating the bridges typically used to support the tension members in molding devices. Eliminating such bridges eliminates the resulting grooves associated with previous arrangements. Providing a grooveless exterior on the jacket (34) of the load bearing member (30) eliminates a significant source of potential vibration and noise in an elevator system.
