A conveying belt has a cylindrical base layer, and a surface layer that is formed on the outer peripheral surface of the base layer. The base layer contains polyimide or polyamide-imide, and has an elastic modulus from 3-7 GPa, inclusive. The surface layer is configured as a cured object from a resin composition that contains a fluororesin having a hydroxy group, an isocyanate curing agent, and a silicone copolymer. The silicone copolymer is a copolymer containing a silicone unit and another kind of unit not having a siloxane skeleton, has a hydroxy group, and contains siloxane units in a proportion of at least 95 mol% and less than 100 mol%, or from 40-70 mol%, inclusive. The silicone copolymer content in the resin composition is 1-5 parts by mass, inclusive, relative to a total 100 parts by mass of the fluororesin and the isocyanate curing agent.

Flat belt apparatuses and methods are provided where one or more cords in the flat belt are tensioned or pre-tensioned to extend the service life of the flat belt.

A belt for suspending and/or driving an elevator car includes a tension member extending along a length of the belt, the tension member including a plurality of fibers bonded in a first polymer matrix, the plurality of fibers extending parallel to and discontinuous along a length of the belt and arranged with one or more lengthwise extending gaps between lengthwise adjacent fibers. A jacket substantially retains the tension member. A method of forming a tension member for an elevator system belt includes arranging a plurality of fibers into a fiber bundle. The plurality of fibers extend parallel to a length of the belt and have one or more lengthwise extending gaps between lengthwise extending fibers. The plurality of fibers is bonded to a first polymer matrix.

A pulley belt (100) for transmitting force from a first pulley (12) to a second pulley (14) includes a belt member (110) having a contact surface (120) configured to be in contact with the first pulley (12) and the second pulley (14). A plurality of projections (122) extends from the contact surface (120). The projections have a predetermined height/diameter aspect ratio. In a method of making a pulley belt, an uncured elastomer (316) is placed in a mold (310) having a shape of a belt member (320) with an inner surface from which patterned projections (312) extend inwardly. The uncured elastomer is cured to form a cured belt member (320), which is removed from the mold (310).
