Abstract
To reduce elongation of a stranded wire rope or cable (1), particularly when running over sheaves, or pulleys, and decrease vibration as well as operating noise while increasing operating speed, insert elements (4) are placed between adjacent rope elements (2). The insert elements, in cross-section, have an intermediate portion part (7) with oppositely positioned concave recesses (9), a head portion (6) which can be widened to the circumferential diameter of the rope or cable (1) and a widened base portion (8).
The base portions (8) have preferably a wedge shape (8) and are not interconnected. The insert elements (4) are reinforced with a fabric material (16), which is integrated into the material of the inserts, and located, for example adjacent the concave recesses. The fabric is a woven fabric of fibrous or monofilamentary material, yarns or threads.

Description
STRANDED WIRE ROPE OR CABLE HAVING MULTIPLE
STRANDED ROPE ELEMENTS AND STRAND SEPARATION INSERT
MEANS
FIELD OF THE INVENTION
The present invention relates to a stranded wire rope or cable, especially a cable made of steel strands which strands, in turn, are formed by steel strand wire elements, and to a strand separation insert. Preferably, the cable has at least four or six spirally distributed stranded elements, stranded together.
BACKGROUND
It is customary to make wire ropes or cables by twisting already stranded wire rope elements in a stranding machine about a core. This spiral twisting causes deformation of the initially round core due to the radial pressure being exerted by the rope or cable elements. The wire rope or cable thereby receives the final shape or form.
STRANDED ROPE ELEMENTS AND STRAND SEPARATION INSERT
MEANS
FIELD OF THE INVENTION
The present invention relates to a stranded wire rope or cable, especially a cable made of steel strands which strands, in turn, are formed by steel strand wire elements, and to a strand separation insert. Preferably, the cable has at least four or six spirally distributed stranded elements, stranded together.
BACKGROUND
It is customary to make wire ropes or cables by twisting already stranded wire rope elements in a stranding machine about a core. This spiral twisting causes deformation of the initially round core due to the radial pressure being exerted by the rope or cable elements. The wire rope or cable thereby receives the final shape or form.
Difficulties arose in use of such wire ropes or cables due to elongations which may be permanent. Measures must be taken to compensate for elongation and maintain necessary tension on the wire rope~When the wire ropes are passed about sheaves, pulleys, or the like, vibrations can be transferred from the rope, or the sheaves or pulleys to structural or machine parts. The vibrations are a consequence of the helical surface of the wire rope running off support rollers or sheaves. Such vibrations in many instances limit the possible speed of operations of the rope, and hence the transport capacity of carriers or the like connected thereto.
THE INVENTION
It is an object to provide a stranded wire rope or wire cable, and typically a stranded steel wire rope having multiple strand stranded rope elements which, in comparison to conventional wire ropes or cables has a substantially decreased remanent elongation when in operation, and which is less, or hardly at all subject to vibration when running over rollers or pulleys, while having an increased life-time; substantially as a result of separating inserts suitable for separating stranded rope elements of the stranded wire rope, or cable.
Briefly, adjacent stranded rope elements of the wire, rope or cable areseparated from each other by inserts in forms of tapes or ribbons, placed on edge, which have a head portion at the outer circumference of the wire rope and a base portion a the inside. The head and base portions are enlarged, or thickened with respect to an intermediate portion of the insert tape or strip or ribbon. The intermediate portion is formed with oppositely located concave depressions, and constricting the cross-section of the tape or ribbon. These concave portions engage against the normally round stranded rope elements. The head portions terminate at the theoretical outer diameter circle of the rope or cable. The base portions are separated from each other, that ist, not mutually interconnected.
An insert which is particularly wear and tear resistant and has long life in spite of the high stresses placed on the insert element in operation has an ~ 3 21S~9 integrated fabric placed as an inlay, or reinforcement in at least a concave middle portion of the insert.
It is desirable that wire ropes or cables have as small a diameter as possible, consistent with the required strength, or carrying capability of the cable. To reduce the diameter of such cables, it is necessary to reduce the thickness of the center or intermediate portions of the insert elements.
the intermediate portion, it has been found, is particularly stressed since several force components act thereon. The direction of these force components changes during use of the cable, for example when it runs over a support roller, or a roller pulley or sheave. Forces which act on these inserts are pressure forces, torsion forces as well as bending forces.
Reinforcing the center portion, at least, of the inserts by a fabric, integrated into the inserts, which, typically are made of plastic material, permits substantially improved acceptance of the stresses, and the wear and tear, as well as the acceptance of the forces to which the insert elements are subjected. This improves the lifetime of the overall cable.
The reinforcement material preferably is a textile, and especially a woven textile material; this is in contrast to insert formed of separate fibers or short strands. A fabrik inlay, integrated into the insert element forms an unremovably bonded reinforcement. When subjected to torsion, the support effect obtained by a fabric insert is an improved, areal reinforcement. The individual spirally twisted cable elements do not engage the center or median portion of the insert with a portion of their clrcumference.

DETAILED DESCRIPTION
The stranded steel wire rope or cable I is particularly suitable as a support cable, or as a pull cable, for example for use in cableways, cable cars or the like. The wire rope I is an composite formed of a plurality, preferably at least four, in the example six, or eight wire elements 2. More than eight may be used for special applications.
Each one of the wire elements 2 has seven individual wires which, in turn, can again be stranded wire structures. A larger or lesser number than such individual wires, or composite form of strands, can be stranded together to form one of the rope elements 2.
The insert elements 4 are of ribbon or tape form which have, at the outer side, a head portion 6, a central portion 7 and a base portion 8.
The head portion 6 and the base portion 8 are thickened, in cross-section, with respect to the central portion 7, the radius of the recesses 9 corresponds at least approximately to the circumferential radius of the adjacent rope element 2. The insert elements 4 are not connected to each other.
Two adjacent rope elements 2, thus, engage against the internally bulged, or recessed central portions 7 of the separating tape or ribbon 4, and are spaced by the tape or ribbon 4 from each other.
The head portions 6, as best seen in Fig. 1, are rounded at the outside and end at the theoretical surrounding circle 14 of the rope 1. Consequently, the engagement points for support, guidance, or 21!i99~;
carrying rollers or pulleys is doubled which results in extremely quiet running operation of the rope.
The inserts 4, preferably, are made of a drawn, or pultruded, or of extruded plastic wire or ribbon structure having the profile, or shape as described. Suitable materials are glass fiber reinforced epoxy-vinyl ester resin, or polyethylene. Other materials may also be used for the inserts 4.
The wire or rope or cable 1 of the embodiment of Fig. 1 does not have a central core. The base portions 87 are extended close to the center 12 of the cable; the base portions 8, again, are not interconnected. The base portions 8 has a wedge shape, the apex of which extends up to close the core-less center line 12 of the wire or cable. The wedge sides 15 pushes against each other, but are not interconnected.
The embodiment of Fig. 2 illustrates inserts in which the head portion 6 is widened to the extent that a bulge results which is located in a space formed by the peripheries of two adjacent wire elements 2 and the theoretical circular circumference of the wire or rope 1. This space is filled essentially entirely by the head portion 6 of the insert 4'. Such a cable will have essentially areal contact with rollers or pulleys.
The stranded steel wire rope of any one of the embodiments can be readily made on a customary and standard rope making, or a stranding machine. The insert 4, in accordance with the present invention, can be inserted during stranding similar to additional wires or serving strands, or similar to the rope elements 2, and can be stranded together with the rope elements 2 as they are being supplied.
Fig. 2 illustrates a wire and cable with a central core 10. The diameter of the central core is selected to be so dimensioned that it engages, or touches the wire strands 2, or at least approaches very close to the wire strands 2, with little clearance, which can be taken 21599Sl up, for example, if the cable runs over a pulley. In elongated, straight condition of the cable, however, there may be a slight clearance between the circumference of the central core 10 and the inner circumference of the individual strands 2. The foot or base portion 8' of the insert 4' are formed with a concave inwardly-curved surface 1 1 (Fig. 5) which engages against the core 10. The core 10 is made of a elastomer material, which can be of the same material or similar material as the insert 4 or 4', or a material, at least of the same type.
In accordance with a feature of the invention, and in order to improve the strength of the insert 4, 4' the central, inwardly curved concave portions 7 are reinforced at both sides with a fabrik 16 (Figs. 3,4). The fabrik 16 is close to the surface and irremovably bonded to the material of the insert 4, 4', that is, it is integrated into the material. The fabrik, preferably, is made of threads or yarns of man-made fibers, glass fibers, or natural fibers or a fabric made of or including mono-filamentary materials. The fabric, preferably, is woven .
The inserts 4, 4' preferably are made in the form of an extruded plastic tape or ribbon profile. A particularly suitable material is glass fiber reinforce epoxy-vinylex resin, or polyethylene.
Fig. 5 illustrates an embodiment in which a fabric reinforcement 16 is located at least essentially in the symmetrical vertical cross-sectional plane of the insert 4'. The fabric insert 16 is shorter than the entire height of the insert element 4'.
It is also possible to reinforce the head portion 6 as well as the bottom or foot portion 8 by wrapping the fabric 16 over the entire insert element, and bonding the fabric thereto, for example just beneath the surface thereof.
Additional reinforcements may be formed in the inserts, for example by introducing longitudinal monofilaments or fibrous filaments, as - -7- 21~;99,~
desired, in the head portion 6, and/or in the bottom or foot portion 8, and/or in the central portion 7.
The reinforcement fabric 16, and the insert strands, if used, are extruded together with the elastomer material forming the insert, so that the result will be a reinforced unitary structure, in which the reinforcement material is irremovable from the body of the insert as such.
The inserts 4, 4' are spiralled together with the wire element 2 when the cable is finished.
Various changes and modifications may be made and any features described herein may be used with any of the others, within the scope of the inventive concept.
