A pultrusion method for making a composite elevator belt includes pulling at least one load carrier strand coated with a core layer into a pultrusion die including a plurality of molding teeth and intervening spaces between the molding teeth having a profile shaped to form a desired profile of belt teeth on the core layer. The method further includes filling the intervening spaces between the molding teeth of the rotating die with resin, depositing the resin on the core layer, forming a plurality of the belt teeth on the core layer using the rotating die, pulling the core layer with formed belt teeth into a jacket extruder, and forming a jacket layer on the core layer with the formed belt teeth to complete the composite elevator belt.

An elevator belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a core member formed from a composite material, and a plurality of second fibers to enhance temperature resistance of the tension member. A jacket material encapsulates the tension members. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a core member formed from a composite material, and plurality of second fibers to enhance temperature resistance of the tension member. A jacket material at least partially encapsulates the tension members.

A composite wire has a thermoplastic core component and a sheath. The sheath includes at least two groups of reinforcement threads wrapped around the core component. The at least two groups of reinforcement threads form angles with the core component, with the overall sum of all angles which are essentially zero.

A wire rope formed from a resin core and six strands, the resin core having an inner core with a circular cross section and an outer layer built up on the periphery thereof. The outer layer has a melting temperature lower than that of the inner core. The six strands are twisted together helically on the periphery of the resin core in an intertwining die in such a state that gaps are assured between the strands. The resulting wire rope is heated in a heating unit at a temperature higher than the melting temperature of the outer layer but lower than the melting temperature of the inner core. The wire rope is formed by subsequently compressing the six strands from the periphery thereof in a compressing die. The molten outer layer is hardened by natural cooling, after which the wire rope is taken up.

A security device has a flexible strap (26) with a lock unit (28) attached at each end. The strap (26) comprises a plurality of longitudinally extending multi-filament cables or ropes (2) arranged in a substantially planar array embedded in an elastomeric material (4). The cables or ropes (2) have a coating of primer for creating a bond with the elastomeric material (4). The primer may be restricted to the external surface of the cables or ropes (2), or some of the surfaces of the filaments may be free of primer. This facilitates relative movement of the filaments during flexure or compression of the strap (26). Moreover, an extrusion process for manufacturing the strap (26) including a priming station (12) is disclosed.

An end fixing structure of a composite wire rod includes a composite wire rod, a wedge body that is formed into a cylindrical shape with an enlarging diameter from a front end portion, wherein an inner wall surface is formed for engaging with the outer surface of the composite wire rod which is copied onto the inner wall surface, and a sleeve provided on an outer peripheral side of the wedge body and having a conical and hollow inner structure, and the wedge body consists of a plurality of divided wedge bodies, facing each other on their divided surfaces with a space therebetween, and the inner wall surface in the divided wedge body is made of microscopic irregularities, thereby shortening a processing time and maintaining a sufficient gripping power over long term.

A belt (30) for suspending and/or driving an elevator car (14) includes a plurality of tension elements (32) extending longitudinally along a length of the belt, at least one tension element of the plurality of tension elements having one or more tension element coating layers (46) applied thereto. A plurality of fibers are interlaced with the plurality of tension elements forming a composite belt structure. A belt coating (44) at least partially encapsulates the composite belt structure.
