A method for manufacturing rope is disclosed. The method includes receiving a plurality of thermoplastic polymer or resin impregnated rovings, combining the plurality of thermoplastic polymer or resin impregnated rovings into a combined roving, tensioning the combined roving, heating the combined roving, removing excess thermoplastic polymer or resin from a surface of the combined roving, and chilling the combined roving while under tension.

A method for manufacturing a flexible composite belt or cable, in the method, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. In the coating treatment, the reinforced plastic profiles are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.

The present invention relates to a polymer composite having a multi-layered structure formed by implanting one or more steels and fibers into a polymer and adhering the one or more steels and fibers to the polymer and thus being lightweight and having high strength, high toughness, and high wear resistance. The polymer composite includes a polymer, a filament implanted into the polymer and adhered to the polymer, and a fiber implanted into the polymer and adhered to the polymer, in which either only the filament or the fiber is implanted into the polymer and adhered to the polymer, or the filament and the fiber are simultaneously implanted into the polymer and adhered to the polymer.

Provided is an elastomer reinforcement cord with improved rust resistance. An elastomer reinforcement cord 10 includes metal filaments and a polymer material. The elastomer reinforcement cord 10 has a multi-strand structure which includes: at least one core strand 21 formed by twisting plural metal filaments 1a and 1b together; and two or more sheath strands 22 each formed by twisting plural metal filaments 11a and 11b together, the sheath strands being twisted together around the core strand. An intra-sheath-strand filling rate a, which is a ratio of the area of the polymer material with respect to an intra-sheath-strand gap region A, is 52% or higher, and an inter-strand filling rate b, which is a ratio of the area of the polymer material with respect to an inter-strand gap region B, is 75% or higher.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, each tension member including a plurality of load carrying fibers, the plurality of load carrying fibers including a plurality of aromatic polyester based fibers. A jacket material at least partially encapsulates the plurality of tension members.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, a jacket material at least partially encapsulating the plurality of tension members, and a primary overlay layer applied to one or more of the plurality of tension members or at least a portion of the jacket material. An elevator system includes a hoistway, an elevator car 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 belt length, a jacket material at least partially encapsulating the plurality of tension members, and a primary overlay layer applied to one or more of the plurality of tension members or at least a portion of the jacket material.

A coated PC steel stranded cable includes: a stranded cable in which a plurality of elemental wires each composed of steel are twisted together; an anti-corrosive coating having an outer circumferential portion that coats an outer circumference of the stranded cable; an outer coating that coats an outer circumference of the anti-corrosive coating; and an optical fiber provided at a position inwardly of an outer circumferential surface of the outer coating and corresponding to a strand groove in the stranded cable so as to follow expansion and contraction of the stranded cable.

A method for manufacturing a tension member, in particular for use in a belt or in a belt segment, having the steps of: preparing a tension member which has a plurality of tension member strands and filling at least some of the intermediate spaces between the tension member strands with a filling material at least at one open end of the tension member, wherein the tension member remains free of the filling material toward the outside.

A material based on fibre-reinforced materials such as carbon-fibre reinforced plastics, prepegs, towpregs, with at least one locally pre-treated polymer covering. The covering has a hardness gradient, that is, from harder to softer from the inside to the surface of the covering.

A method of making a hoist cable capable of continuous resistance monitoring includes applying an electrically-insulating material to at least one strand of a wire rope such that a length of the strand is electrically insulated and an end of the strand is electrically conductive. The end of the at least one strand is joined to other strands of the wire rope such that at least two strands are electrically connected at a free end of the wire rope. A method of inspecting the hoist cable includes transmitting a first electrical signal through a first strand from a hoist drum to a free end of the wire rope and receiving the first electrical signal through a second strand at the hoist drum, the first and second strands being electrically connected at the free end. Using the first electrical signal, the resistance of the wire rope is calculated.
