Abstract
Wires (4) are drawn from a stationary supply spool or reel system (1, 2) and a winder (19) which receives the material (12) in finished stranded condition is arranged within a rotating flyer of a double-twisting machine (31). The finished cable which is produced upstream of the machine is no longer altered in the movement of being guided around the winding means (19), because disposed upstream and in the stranding machine are twisting means (10, 16) which both rotate synchronously but in opposite directions, and these two twisting means rotate at double the speed of the arcuate guide means (14). <IMAGE>

SPECIFICATION
Method and apparatus for producing multilayer steel wire cables
The present invention relates to a method and an apparatus for producing multilayer or multiply steel wire cables, wherein the individual wires are drawn from stationary supply or run-off spool systems and the winder is arranged within a rotating system in the form of a double stroke stranding machine.
High-speed stranding machines are predominantly used, for the production of generally conventional multilayer or multiply steel wire cables. The stranding rotors of such machines comprise either rotatable tubes or rotatable wire guide means. The run-off or supply spools or reels for the wires to be stranded are usually mounted within the stranding rotor in individual reel or spool carriers. The wires are usually passed from the supply reels or spools to the axis of the rotor, then deflected outwardly and guided along the rotor to the stranding point, where they are stranded. The stranded material is then fed by way of a take-off means to a winding spool or reel.
The quality of the products produced with those machines is high.
High-speed stranding machines have been the subject of continuous development over the years, so that the elements which determine the production capacity thereof such as, for example, the stranding basket rotor are so highly loaded that the materials used have reached the limits of their load-carrying capacity and even those limits are only achieved by a high degree of precision in manufacture, that is to say, a high level of technical expenditure. At the same time, the liability to trouble of the machines is increased. Attempts have therefore been made to use the double stroke principle which is frequently employed for stranding soft or plastic materials such as copper and aluminium, for stranding steel wire.
The inherent torsion in the individual wires, which is caused thereby, resulted in considerable difficulties and gave poor quality products.
DE-AS No 15 10 062 discloses a process and an apparatus for producing torsional stress-free wire cables. Therein, the wires are drawnofffrom the stationary supply or run-off frame structures and fed to a twisting means in which the individual wires are twisted about their longitudinal axis. The wires are then passed to a stranding point in which they are stranded together. Finally, the stranded material is wound on, within a rotating winding means. In that connection, the winding means represents, from the point of view of the principle involved, a double stroke stranding machine.
That construction has a low level of mechanical engineering expenditure and requires a small amount of space, in comparison with the use of high-speed stranding machines. However, it is not suitable for high-quality production of a multilayer cable at a high production rate.
The main disadvantage of the above-indicated solution is that the two strokes of a double stroke stranding machine are not combined in respect of location. Thus, in the region in which the stranded material is guided in the cage of the winding means, the material suffers from being partially twisted, which means that the precise layer structure required is no longer guaranteed.
A further disadvantage is that the selected cage form with the elongated guide means for the stranding material and the arrangement of the take-off means in rotary form upstream of the winding means does not permit high speeds of rotation.
DD-WP No 143279 discloses a stranding apparatus for producing multilayer or multiply steel cables, in paticular steel cord. Described therein is an apparatus wherein the individual wires are fed between two twisting means which rotate synchronously. While the wires for the individual layers or plies of the cable to be produced are not rotated, the core wire or centre portion is rotated. That occurs at the same speed of rotation and in the same direction of rotation as the movement of the stranded material atthewinding means.
However, that solution does not make it possible to produce twist-free stranded material, because of the absence of reverse twisting of the individual wires.
Furthermore, that apparatus also does not ensure that there is no twisting of the cable in the guide means around the reel carrier of the winding means, as a consequence of the double stroke principle.
Therefore, that apparatus does not ensure that production of the cable is of the proper quality.
The invention is based on the problem of developing a process and an apparatus for producing multilayer steel wire cables wherein the finished cable produced upstream of the double strike stranding machine is not altered any more in the path of movement around the winding means.
According to the present invention in one aspect there is provided a method for producing multilayer steel wire cables wherein the wire strand are drawnoff stationary supply spool or reel systems and the individual wire strands are rotated about their longitudinal axis, the finished composite stranded material being produced before passing into a double stroke stranding machine, said wire strands being drawn from the supply spool or reel system under a constant tension, individually twisted in twisting means and, depending on the structure of the composite stranded material to be produced, passed by way of one or more stranding discs with corresponding stranding points to a twisting means, subjected to finishing stranding therein and, by way of direction-changing systems and guide means, then passes through a twisting means which is disposed in the double stroke stranding machine and which has a synchronous speed of rotation but in the opposite direction of rotation to the twisting means disposed upstream of the double stroke stranding machine and which rotates at double the speed of the direction-changing systems and guide means, and the stranded material is then fed to a winding system.
In the twisting means, the final cable stranding operation is carried out. The cable in finished stranded form is then fed to the winding system by way of guide rollers, guide means and a further twisting means. In that arangement, the two twisting means have synchronous speeds of rotation but in opposite directions relative to each other. In comparison with the rotary speeds of the deflection or guide means, the speeds of rotation of the twisting means are doubled.
It is within the scope of the invention that, for producing a stranding bond or composite stranded structure comprising individual wires of the same diameter, the individual wires are fed by way of a common stranding disc to the twisting means for producing the finished stranded structure. If wires of different diameters are used, the individual twisted wires pass in layers through a plurality of successively disposed stranding discs, with the respectively associated twisting means.
According to the present invention in another aspect there is provided apparatus for carrying out the method according to the invention comprising supply reels or spools provided with braking systems, a twisting means for producing the finished composite stranded product and disposed between the supply reels or spools and the twisting means are pre-twisting means with clamping means and a stranding disc with its stranding points for receiving the wires supplied in layers through guide bores in the disc, and disposed between the twisting means and a winder having displacement means are direction-changing rollers which are connected together by way of an arcuate guide means, as well as a twisting means and a take-off means with postforming means.
It is also within the scope of the invention that disposed between the twisting means arranged upstream of the double stroke stranding machine and the winder with its displacement means, which is within the double stroke stranding machine, are direction-changing or guide rollers which communicate with each other by way of an arcuate guide means, as well as a twisting means and a take-off means with post-forming means.
The mode of operation of the invention is described hereinafter.
The individual wires are drawn off the supply reels under constant tension and are passed by way of a clamping means to a twisting means. In the twisting means, the individual wire is twisted or rotated about its longitudinal axis. The individual twisted wires are now passed to a stranding disc which receives the wires, in layers, in bores, the wires being sorted out or classified at that point, and then being fed to the corresponding stranding points. The stranded material is then fed to a twisting means which operates at double the speed of rotation relative to the direction-changing or guide rollers within the double stroke stranding machine, with the material thus being stranded by the twisting means.
The finished cable now passed by way of directionchanging or guide rollers and an arcuate guide means to a further twisting means which is disposed within the double stroke stranding machine. The twisting means has a synchronous rotational speed with the twisting means disposed upstream of the double stroke stranding machine, but rotates in the opposite direction. After passing through said twisting means, the stranded material is fed by way ofthe take-off means with post-forming means to the winder with its displacement means, where it is wound on.
The use of the twisting means at the end of the arcuate guide means and the twisting means upstream of the double stroke stranding machine ensures precise guidance in respect of the steel wire cables which are alreadyfinished upstream ofthe arcuate guide means.
Two embodiments of the invention will now be described, by way of examples, with reference to the accompanying drawings, in which:
Figure 1 is a view of an entire apparatus, having a single stranding disc and constituting a first embodiment;
Figure 2 is a view of the front portion of an apparatus having a plurality of stranding discs and constituting a second embodiment; and
Figures 3 to 7 shows examples of the structure of cables.
Referring to Figure 1, the stranding assembly comprises a run-off or supply frame structure having delivery or supply reels 1 and 2 which are each provided with a braking system 3. The use of the braking system 3 ensures a virtually constant tension in the wire over the entire content of the respective reel.
From the reels 1 and 2, each wire 4 is fed to a twisting means 5. Disposed directly upstream of the twisting means 5 is a clamping means 6 which, in conjunction with the constant wire tension, ensures a constant working point, that is to say, a constant path between the twisting means 5 and the clamping means 6. That working point is the same for all wires 4 which are twisted with the same rotational twisting speed. The twisting means 5 all rotate in one direction, more specifically in the same direction as the subsequent stranding step.
The drive of the twisting means 5 is variable so that either all twsiting means 5 rotate at the same speed or only the twisting means 5 which guide wires 4 of the same layer or the same thickness in the later composite stranded element 12 rotate at the same speed. From the twisting means 5, the wires 4 are fed to a stranding disc 7 in which they are arranged in accordance with their subsequent position within the composite stranded element 12 by guide bores 30 and are fed in layers to a respective stranding point 8 and 9. The wires 4then pass through a pair of rollers 11 within the twisting means 10. The composite stranded element 12 is thus produced by the rotational movement of the twisting means 10. The finished stranded composite element 12 in the form of a multilayer cable (see Figures 3 to 7 for examples) is now fed to a further twisting means 16 by way of a direction-changing or guide roller 13, an arcuate guide means 14, and a directionchanging or gjuide roller 15, and all three rotate about the axis of rotation of the double stroke stranding machine 31. In that connection, the two twisting means 10 and 16 rotate at twice the speed of the arcuate guide means 14 of the machine 31. The direction of rotation of the twisting means 16 is opposite to that of the twisting means 10.That provides for constant rotation of the cable 12 which is in a finished stranded form upstream of the first twisting means 10, about its own axis, at the speed of rotation of the two twisting means 10 and 16, in the path by way of the arcuate guide means 14 into the machine 31. Within the machine 31 is located a take-off means 17, a post-forming means 18 and a winder 19 with its displacement or transfer means 20 disposed on a reel carrier means. The material 12 is passed to those components, after leaving the twisting means 16.
Figure 2 shows an alternative embodiment regarding the configuration of the individual stranding points and the stranding disc. In this arrangement, for each stranding layer or ply, there is a respective stranding disc 21,22 and 23, associated with the corresponding stranding points 27, 28 and 29 and twisting means 24, 25 and 26. This embodiment is used when dealing with individual wires of different diameters.
Figures 3 to 7 are cross-sections through cables showing different lay-ups which can be produced using the apparatus of the present invention.
