A drive sheave of an elevator for use with a coated steel cord comprises a metal body and separators. The metal body has shallow circumferential grooves with a groove depth. The grooves are separated from one another with separators that extend out of the metal body much more than the groove depth. The separators are made of or are provided with a low friction coating. The friction coefficient between the separators and the coating of the coated steel cord is much lower than the friction coefficient between the metal body and the coating of the steel cord. The metal body can be assemble out of discs each having a single groove. The friction force of the coated steel cord can further be influenced by making the groove width less than the diameter of the coated steel cord. An elevator comprising coated steel cords running over the sheave is also claimed.
The invention relates to a clamp or termination for a coated elevator rope in an elevator. When coated elevator ropes are used electrostatic charge may build up in the ropes due to the insulating coating. These charges generate repelling or attracting forces between the parallel ropes, which hampers the correct miming of the ropes in the pulleys and in extreme cases may derail the coated elevator ropes. The wedge and socket clamps according the invention discriminate themselves from prior art wedge and socket clamps in that the piercing instruments are provided in the low tension zone of the clamp. These piercing instruments can take the form of pins, fins or other protrusions and establish an electrical connection between the wedge and the conductive tensile member. Such an elevator clamp allows to leak static electricy being build up or allows wear detection per elevator rope.

Reinforcement strand for reinforcing a polymer article
A reinforcement strand (400) comprises a core (403) around which steel filaments (404) are twisted all with the same final lay length and direction. The steel filaments are arranged in an intermediate layer comprising N first steel filaments and an outer layer of 2N steel filaments circumferentially arranged around the intermediate layer. In the intermediate layer filaments will contact one another at a closing lay length that is determined by the number of steel filaments N in the intermediate layer, the diameter of the core and the diameter of the first steel filaments. By choosing the final lay length and direction equal to the between two and six times the closing lay length gaps will form between the intermediate layer filaments. The 2N outer layer filaments are further divided into a group of smaller (408) and a group of larger (406) diameter steel filaments.
A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope contains a core surrounded by multiple strands. The outer filaments of the core and the outer filaments of the strands are likely to contact one another during use. The outer steel filaments of the core have an average Vickers hardness that is at least 50 Vickers hardness numbers lower than that of the outer filaments of the strands. As the hardness of the outer filaments of the core is substantially lower than that of the outer filaments of the strands, those softer filaments will preferentially abrade away during use. In this way the core is sacrificed while preserving the integrity of the outer filaments of the strands. The use of this ‘sacrificial core’ results in a higher residual breaking load after use.
An elevator tension member is presented that has one or more steel cords as strength members that are encased in a jacket of thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer is selected on the basis of its thermal properties in that the glass transition temperature of the hard phase (Tg HS) is above 90° C. In preferential embodiments that thermoplastic polyurethane elastomer has a crystallisation temperature (Tg) that is at least 20° C. higher than Tg HS. In other preferential embodiments the sum of Tg HS and Tc is higher than 200° C. Such thermoplastic polyurethane elastomers exhibit an unexpected increase in useful lifetime when compared to conventionally used polyurethanes. Moreover the invention provides a simple method to select an appropriate thermoplastic polyurethane elastomer.
A belt containing steel cords, the steel cords containing strands made of steel filaments wherein the largest diameter filaments are at least intermittently positioned at the radially outer side of the steel cord. Such a configuration can be obtained by using steel cord constructions wherein the thickest filaments are positioned outside of the steel cord which is contrary to the current practice. In a further embodiment the largest diameter filaments fill up some or all of the valleys of the strands at their radially outer side. These monofilaments thus have the same lay length and direction as the strands in the steel cord. The advantage of putting the largest filaments at the outside is that they will break first and thus will be readily detectable by electrical, magnetic or visual means. In this way a belt is provided that can be monitored easier and more conveniently than prior art belts.

A steel cord for the reinforcement of elastomer products such as elevator belts, conveyor belts, synchronous or timing belts or hoses or tyres is presented. The steel cord comprises strands and monofilaments made of steel filaments. The strands themselves are also made of steel filaments twisted together. The strands form the outer layer of the steel cord. The monofilaments are twisted into the cord with the same lay length and direction as the strands and are positioned in the valleys between the strands on the radial outer side of the steel cord. The steel cord has the advantage that it has a better fill factor and a rounder aspect. Furthermore the monofilaments may act as an early wear indicator of the elastomer product.
A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope comprises a core surrounded by multiple strands. The outer filaments of the core and the outer filaments of the strands are likely to contact one another during used. The outer steel filaments of the core have an average Vickers hardness that is at least 50 Vickers hardness numbers lower than that of the outer filaments of the strands. As the hardness of the outer filaments of the core is substantially lower than that of the outer filaments of the strands, those softer filaments will preferentially abrade away during use. In this way the core is sacrificed while preserving the integrity of the outer filaments of the strands. More preferably the core has a Vickers hardness that is lower than 600 HV. The hardness of the steel wire is a function of many factors such as carbon content, degree of cold deformation during drawing, heat treatment etc... Different variants of the idea are presented. The use of this 'sacrificial core' results in a higher residual breaking load after use. The coated steel wire rope comprises one steel wire rope and a polymer jacket surrounding the steel wire rope. The belt comprises several steel wire ropes arranged side-by-side and held together by the polymer jacket.
A belt for use as for example an elevator belt, flat belt, synchronous belt or toothed belt comprises steel strands held in parallel by a polymer jacket. The steel strands have a diameter ‘D’ and are separated by a pitch ‘p’. The ratio of diameter ‘D’ over pitch ‘p’ is larger than 0.55. Such belt arrangement prevents the cutting of the polymer jacket between strand and pulley and abates the noise generation during use. The belts are best built with a type of parallel lay strands particularly designed for use in a belt. These strands do not show core migration during use of the belt.

APPARATUS FOR DETECTING COATING ON WIRE AND A METHOD TO USE SUCH APPARATUS
The invention relates to a measuring cell for optically verifying the presence of a coating on a wire specifically a steel wire or steel cord. As steel wire or steel cords are generally thin and round measuring the light reflected or emitted from the surface of a wire is difficult. The coating is optically active in that it absorbs or emits radiation in response to impinging light. The measuring cell comprises a dark cavity with an entrance and exit orifice. Two or more sources illuminate the wire towards a central spot. Radiation reflected or emitted from the coating is detected by two are more detectors. Different arrangements for the positioning of the sources and detectors are suggested. The invention further describes a method for using the measuring cell as well as an apparatus to controllably coat the surface of a wire.

A flexible rack for use in a drive system such as a window elevator system, sunroof drive system, sun shade or cover actuators in a vehicle comprises a steel cord embedded in a polymer jacket. In the polymer recesses are provided at regular distances that engage with the teeth of the drive gear. In order to act as a backbone to the flexible rack, the steel cord must account for at least 90% of the total longitudinal stiffness of the flexible rack otherwise it succumbs to compressive stresses and/or stretches too much under tensile loads. In contradistinction therewith the bending stiffness contribution of the steel cord must remain below 15% of the total bending stiffness of the flexible rack so that the flexible rack can follow the curvature of the guiding channel the flexible rack is running in. By preference the steel cord is free of second and higher order helical deformation. Particularly preferred is that the steel cord is situated slightly 'off- centre' as therewith a preferred bending direction is induced.
A flexible rack for engagement with the gear of a drive system comprises two or more steel cords that are arranged parallel to one another in the longitudinal direction. The steel cords are surrounded by a polymer jacket wherein recesses are provided for engagement with the teeth of the drive gear. The centres of the steel cord are in a plane that is perpendicularly to a mirror plane of the cross section of the flexible rack. The two or more steel cords have equal numbers of left and right lay direction steel cords. Detailed embodiments have just two S and Z lay direction steel cords of equal construction. Preferred steel cords comprise filaments with second order helical deformation. The distance between the steel cords influences strongly the bending behaviour of the flexible rack and is between 0.80 to 2.5 times the diameter of the steel cord. In a drive system wherein the rack remains in a single plane the distance between the steel cords can be larger than in a drive system wherein bending out of a single plane is also required. The steel cords can be held together by one or more wraps.

ELEVATOR ROPE AND METHOD OF MANUFACTURING SAID ELEVATOR ROPE
An elevator rope (100) comprises a steel cord (114) and an elastomer jacket (140) surrounding the steel cord. One or more yarns (120, 122) are wrapped or braided or knitted around the steel cord before the elastomer jacket is applied. The yarns are therefore integrated into the polymer jacket. The yarns induce a pattern at the surface of the polymer jacket. By amending the yarn structure, the surface pattern of the polymer jacket can be changed. This has an implication on the friction of the elevator rope on the sheave on which it is running. Furthermore, the integrated yarns help to preserve the integrity of the elastomer jacket. In a second aspect of the invention a method is claimed wherein first one or more yarns are wrapped, braided or knitted around the steel cord prior to extrusion of the elastomer. The yarn mantle ensures a good centricity of the elastomer jacket and an improved processability of the elevator rope.
The invention relates to a drive cable for actuating a vehicle element that can move relative to a vehicle body, said drive cable comprising a cable body (26) which is made of a plastic material and has toothing (32), which extends in an axial direction, for engaging with a drive gear (24), a continuous reinforcement structure (30) extending, in an axial direction, through said cable body. The toothing (32) is formed by pocket-like recesses (34) which are spaced from each other at regular intervals in an axial direction and which are limited, in the longitudinal direction of the cable, by flanks of resulting tooth heads (36) and are each limited on both sides, in the transverse direction of the cable, by a pocket flank (38), said pocket-like recesses each being limited at the bottom by a tooth base (40) through which a continuous reinforcement structure extends (30).

A plain stepped splice lay-out scheme is presented that can be used for splicing strips to one another that comprise longitudinally arranged cords. The strips can take the form of a conveyor belt, transmission belt, timing belt, elevator belt, a rubber track or a reinforcing strip. The splice is optimised for uniform bending stiffness and maximum strength retention. The cross section of the strip and the splice are substantially equal: there is no increase in thickness or width at the splice. The splice lay-out is characterised by the fact that the abutments (130)—those positions where cord ends (111, 121) meet—are positioned sufficiently far away from one another and by preference as far away from one another as possible. Preferred embodiments in terms of length common between cords of the different strips and local strength are given.
A splice is described for jointing thermoplastic strips that include steel cords. In the splice a splice polymer is used that is a mixture of a co-polymer and a base polymer, wherein the co-polymer is a grafted co-polymer, a block co-polymer or a random co-polymer functionalized for enabling adhesion to the steel cords. Particular about the inventive splice is that the amount of co-polymer in the base polymer is such that in a test-till-break of a splice, part of the steel cords fracture in the test while the remaining cords are pulled out of the polymer without breaking. Surprisingly, a splice with such a failure behavior results in a better overall splice strength than a splice wherein a too large amount of co-polymer is added. When too much co-polymer is added all steel cords break in the test which strangely enough leads to a lower overall strength of the splice.
