CABLE LAY BRAID AND PRODUCTION METHOD

Abstract

Cable lay braid having a plurality of intertwined twists, wherein each twist is laid from a plurality of twisted strands, characterized in that each strand is formed from a plurality of twisted yarns or twines.

Claims

1. A cable lay braid, comprising: a plurality of intertwined twists, wherein each twist is laid from a plurality of intertwined strands, characterized in that each strand is formed from a plurality of twisted yarns or twines.

2. The cable lay braid according to claim 1, characterized in that each twist is laid from at least one core strand and a plurality of cover strands.

3. The cable lay braid according to claim 2, characterized in that each twist is laid from a core strand and six cover strands or from three core and nine cover strands.

4. The cable lay braid according to claim 1, characterized in that each strand consists of at least three yarns or twines.

5. The cable lay braid according to claim 1, characterized in that there are 4, 8, 12 twists or more.

6. The cable lay braid according to claim 1, characterized in that the twists are twisted to form a square plait or a 12-strand braid.

7. The cable lay braid according to claim 1, characterized in that the yarns have a first or second lay direction (S- or Z-lay) and twines, so far as present, have a first or second lay direction (S- or Z-lay) in equal lay or cross lay.

8. The cable lay braid according to claim 1, characterized in that the strands have a first or second lay direction (S- or Z-lay), wherein the yarns or twines have the same or opposite lay direction in equal lay or cross lay.

9. The cable lay braid according to claim 1, characterized in that the twists have a first or second lay direction (S- or Z-lay), wherein the strands have the same or opposite lay direction in equal lay or cross lay.

10. The cable lay braid according to claim 1, characterized in that the yarns or twines comprise monofilaments with circular, oval, polygon or many times rounded cross-section or consist of such.

11. The cable lay braid according to claim 1, characterized in that the yarns or twines and/or the strands and/or the twists are enhanced or the entire cable lay braid is enhanced.

12. A rope having a cable lay braid comprising: a plurality of intertwined twists, wherein each twist is laid from a plurality of intertwined strands, characterized in that each strand is formed from a plurality of twisted yarns or twines, characterized in that the cable lay braid is embodied as a single braid, as core in a double braid, as core cover braid, or as multi-core braid.

13. A method for producing a cable lay braid, comprising: creating twists from a plurality of intertwined strands, wherein each strand is formed from a plurality of twisted yarns or twines and interweaving a plurality of twists to form a cable lay braid.

14. The method according to claim 13, characterized in that the yarns or twines, strands and/or twists are enhanced prior to twisting or intertwining or the entire cable lay braid is enhanced.

15. The method according to claim 14 wherein the enhancing comprises a step of fixing, stretching, pigmenting, or coating.

16. The cable lay braid according to claim 11 wherein the enhancing comprises a fixing, stretching, pigmenting, or coating.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0022] The invention is described below on the basis of an exemplary embodiment, reference being made to a construction, wherein

[0023] FIG. 1 shows a side view of a cable lay braid according to the invention, and

[0024] FIG. 2 shows a magnified section from FIG. 1.

DETAILED DESCRIPTION

[0025] FIGS. 1 and 2 show the multi-step structure of the cable lay braid 1 according to the invention in relation to the state of the art which in the way known per se consists of a number of laid or twisted twists 2. In the illustrated example eight twists 2 are intertwined as a whole or expressed differently looped through each other. Each twist 2 is formed from 4 strands in a wire rope-type arrangement with an inner and six outer or surrounding strands 4.

[0026] Each strand 4 is again formed from a number of twisted yarns 6, in the present example 12 yarns 6.

[0027] An advantageous variant of a cable lay braid is formed from 12 twists.

[0028] Alternatively, to the afore-described structure a twist can be formed from 12 strands, particularly in a wire rope-type construction, wherein three inner strands and nine outer strands are twisted to form a twist.

[0029] The crucial difference of the invention to prior-art braids consists of the fact that not strands, but twists are or become intertwined or expressed differently the intertwined strands are constructed as twists. Such a twist is laid from strands and consists of a plurality of strands, e.g. 7 or 12, as described.
