The invention relates to a drive belt for a traction mechanism drive, having a radially externally arranged top layer (4) composed of a fiber-containing elastomer or of an elastomer comprising a fiber mesh, having a radially centrally arranged tension member layer (6) composed of a wound tension strand or a plurality of circumferentially oriented tension strands, and a radially internally arranged substructure (8) composed of an elastomer, wherein at least one wedge-shaped rib is integrally formed in the substructure (8), a coating layer (10) composed of a circumferentially open fiber mesh being applied to the outer surfaces of said wedge-shaped rib. In order to prevent an abrupt change in the friction coefficient at the force-transmitting flanks of the ribs, provision is made for the circumferential ends (12, 14) of the coating layer (10) and a parting joint (16), which is filled by the elastomer of the substructure (8), between said circumferential ends (12, 14) of the coating layer (10) to be covered with a transverse strip (18) composed of a vulcanizable material, wherein said vulcanizable material has a reduced friction coefficient in relation to the elastomer of the substructure (8).

A belt for suspending and/or driving an elevator car extending longitudinally along a length of the belt. An inner belt layer formed from a first material is bonded to the plurality of tension elements at a first side of the belt. The inner belt layer forms an inner belt surface interactive with a traction sheave of an elevator system. An outer belt layer formed from a second material is bonded to the plurality of tension elements at a second side of the belt. The plurality of tension elements are located between the first side and the second side.

A fire-resistant material according to an example of the present disclosure includes a base material and at least one of a siloxane polymer and a phosphonate polymer. A method of making a fire-resistant material is also disclosed.

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.

Provided is an endless belt which can improve rotational durability when compared to a conventional endless belt. This endless belt is formed in a tubular shape and is used for electronic photographing apparatuses. The endless belt has an edge part which is formed on at least one belt edge in the belt width direction and which has an end that is tapered toward the outside of the belt width direction. The edge part can be configured by a first edge part formed by intersecting an outer inclined surface with a belt inner circumferential surface, a second edge part configured by intersecting an inner inclined surface with a belt outer circumferential surface, or a third edge part configured by intersecting the outer inclined surface with the inner inclined surface.

A power transmission belt is at least partially formed of a rubber composition. The rubber composition contains a rubber component, cellulose nanofibers, and carbon black. The amount of the cellulose nanofibers to be added is from 0.1 parts by mass to 20 parts by mass, relative to 100 parts by mass of the rubber component. The amount of the carbon black to be added is from 5 parts by mass to 80 parts by mass, relative to 100 parts by mass of the rubber component. The sum of the amount of the carbon black to be added and three times the amount of the cellulose nanofibers to be added is from 15 to 90.

A method for producing a sheet-like composite fabric material, in particular a rubberized fabric or a fabric provided with a polymer preparation, for covering drive belts, the composite fabric material comprising a textile integrated in a matrix of elastomeric material, preferably at least one fabric layer integrated in a rubber matrix, the textile or the fabric layer and the elastomeric material being introduced into a gap between a band and a cylindrical molding wheel and molded to form a composite material between the band and the molding wheel at a temperature below the vulcanization temperature, the band looping around the molding wheel at a looping angle under pressure. Likewise disclosed is a drive belt with a covering of composite material produced according to the invention.

An extruded strap is produced of a material containing renewable raw materials and the ends of which strap can be welded together. A method for producing the extruded strap and a method for strapping an article using the extruded strap are also provided.
