Definitions

  • My invention relates to the roping of strands into cable.
  • the twisting apparatus includes a rotary frame which carries a pair of rolls respectively having parallel axes which extend transversely with respect to the throughput direction of the strands, these rolls acting as an intermediate accumulating or storing means for the strands.
  • a given section of the cable which has a uniform twist direction and twist length is stored at the storing means formed by these rools, and then with a different twisting direction the stored strands are withdrawn from the storing rolls.
  • This known method and apparatus makes it possible to provide a cable having successive sections which are differently twisted and which may have any desired number of twists therein.
  • this known method and apparatus has the disadvantage of requiring the storing rolls to rotate about the twist axis with the number of revolutions required for twisting. The manufacturing speed of such an apparatus is therefore limited, not only because of the necessity of rotating the storing means but also be;
  • a primary object of my invention is to provide a method and apparatus which will greatly improve the manufacture of communication cable having successive sections which are respectively twisted diiferently one with respect to the next-following section.
  • the strands are twisted by means of a rotary twisting frame which turns around a take-up reel while the cable is delivered to the latter takeup reel in a direction which is opposed to the direction in which the strands are pulled from the supply reels.
  • the individual strands are twisted with a double twist while being delivered to the storing means and are also twisted with a double twist while being withdrawn from the storing means.
  • This method and apparatus of my invention has the advantage of requiring only parts of the twisting apparatus which are of relatively small mass to be rotated about the twisting axis.
  • the strands are twisted while being delivered to and from the storing means by a pair of twisting frames which advantageously are symmetrically arranged with respect to each other.
  • These twisting frames have a common axis which coincides with the twisting axis, and the twisting frames are rotated either in different directions, for the different cable sections, or at dilferent numbers of revolutions for the different successive cable sections.
  • the rotary twisting frames turn at a constant speed and in the same direction.
  • FIGS. 1-3 are respectively schematic illustrations in side elevation of different possible embodiments of roping apparatus and methods of my invention.
  • FIG. 4 is a schematic illustration of the manner in which the embodiment of FIG. 1 can be used in a roping apparatus :for combining a plurality of quads into a single cable bundle.
  • FIG. 1 there is illustrated therein a substantially U-shaped supporting frame 1 which supports for rotary movement a pair of rotary twisting frames 2 and 3 which are symmetrically arranged with respect to each other and which are supported for rotation at the locations 4 and 5, so as to form the roping apparatus shown schematically in FIG. 1.
  • guide rollers 7 are provided for guiding the cable and changing the direction of movement thereof, these guide rollers 7 being supported for rotary movement on the twisting frame 2, while the twisting frame 3 has additional guide rollers 8 mounted thereon for rotary movement.
  • the pair of twisting frames 2 and 3 rotate about a given space in which an intermediate storing means is situated, this storing means taking, in FIG.
  • the form of a single accumulator roll 9 which is supported for free rotary movement at the bearing locations 10 and 11 of the twisting frames.
  • the axis of rotation of the accumulator roll 9 extends perpendicularly across the twisting axis, and the accumulator roll 9 is supported for free rotary movement on a suitable shaft which is fixed to and extends upwardly from the lower portion of a substantially U-shaped supporting frame 12 which carries the rotary guide rollers 13 for the cable 6.
  • the rotary accumulator roll 9 has a stationary axis of rotation so that it does not take part in the rotary movements required for twisting the strands.
  • the strands are twisted into the cable 6 which then by means of the guide rollers 7 is guided around the intermediate storing means 9 and while being advanced in a direction opposed to that in which the strands are withdrawn from their supply reels is wound onto the accumulator roll 9 which simply rotates freely as a result of the winding of the cable thereon.
  • the cable 6 is again twisted in the same direction, so that in a manner which is known per se a double twist is imparted to the cable.
  • a predetermined section of cable having a uniform twist direction and twist length is thus stored on the storing means 9, and then while the apparatus provides a different twisting direction the cable is withdrawn from the storing means.
  • the twisted cable 6 is guided by the guide rollers 8 of the twisting frame 3 and has a second double twist imparted thereto since the twist direction has changed with respect to the direction of twist during the initial storing of the cable at the storing means 9, or it is possible to achieve a similar result by providing during withdrawal of a given section of cable a different number of revolutions from that which was provided during delivery of the cable to the storage means.
  • the cable which is derived from the twisting apparatus and method of my invention has a fourfold twist.
  • the twist length will then be inversely proportional to the difference between the different numbers of revolutions used for the successive sections. A relatively large difference in the number of revolutions from one cable section to the next, with the same twisting direction, will thus result in a sharp difference between the twist lengths of the successive sections of the cable.
  • the strands which are delivered to the storing means and which are wtihdrawn from the storing means are guided by guide rollers which are supported for rotary movement by a support means in the form of suitable brackets which are situated laterally beside the intermediate accumulator roll structure.
  • a support means in the form of suitable brackets which are situated laterally beside the intermediate accumulator roll structure.
  • FIG. 2 An example of such a construction is illustrated in FIG. 2.
  • this embodiment has the guide rollers 15 and 16 around which the cable is guided so as have its direction of movement changed, and the rollers 15 are supported for rotary movement by brackets 17 which form a support means for these rollers, while the rollers 16 are supported for rotary movement by brackets 18 which also form a support means of my invention.
  • the storing means from a pair of accumulator rolls which have parallel axes, respectively, and these parallel axes of the accumulator rolls may extend parallel to the twisting axis.
  • This construction is also illustrated in FIG. 2 where the pair of accumulator rolls 19 and 20 are illustrated.
  • the accumulator roll 20 serves to distribute the windings of the cable onto the accumulator 19, and these rolls 19 and 20 are arranged in such a Way that the space around which the twisting frames or cable turns so as to be enclosed thereby is used in a much more favorable manner with an arrangement as shown in FIG. 2, so that the storing capacity is increased.
  • guide rollers 21 are provided.
  • the axes of the pair of storing rolls it is furthermore possible to arrange the axes of the pair of storing rolls so that the latter axes are inclined with respect to the twisting axis.
  • rollers 16 are at the same elevation as the rollers behind the latter in the plane of the drawing of FIG. 2, and in this case the cable 6 after passing through the storing means will be guided to the guide rollers 16 which are at the same elevation as the rollers 15. In this way it is possible to operate with a single twisting frame or with only one set of guide roller supporting brackets 17.
  • FIG. 3 illustrates yet another embodiment of a method and apparatus of my invention for providing a cable having a fourfold twist with successive cable sections twisted differently one from the next, such as by having the successive sections twisted in different directions.
  • the method and apparatus of this embodiment also includes, as was the case with FIG. 1, a pair of symmetrically arranged rotary twisting frames 2 and 3.
  • the storing means takes the form of a pair of accumulator rolls 22 and 23 which respectively have parallel axes which are perpendicular to the twisting axis, and the accumulator roll 22 is formed with grooves which extend circumferentially about the accumulator roll so that the roll 22 can be used for distributing turns of the stored cable onto the accumulator roll 23. In this case also the axes of the accumulator rolls remains stationary.
  • FIGS. 1-3 can be used in precisely the same way for the purpose of roping individual strands into cable, as well as for the purpose of manufacturing cable bundles composed of groups of two, three, or five cable units, and also for the purpose of manufacturing main cable bundles from quads, pairs, or threeunit cables.
  • Such an installation will be composed primarily of the delivery apparatus, the apparatus for providing the different twists in the successive sections, and the cable bundling apparatus.
  • the cable bundling apparatus for example, during manufacture of a basic cable bundle from five star quads with strands derived from 20 supply reels, five twisting assemblies each providing different twists for the successive cable sections will be required, with these twisting units or assemblies having, for example, the structure shown in FIG. 1 and described in greater detail above. All of these twisting assemblies, each of which has the structure of FIG. 1, will then be combined into a single unit.
  • FIG. 4 An apparatus where a plurality of quads are treated with the method and apparatus of my invention as shown in FIG. 1 and then combined into a single cable bundle is schematically illustrated in FIG. 4.
  • the structure illustrated therein will provide a communication cable composed of groups of twisted cable with four twisting assemblies, each corresponding to that of FIG. 1, arranged in parallel for twisting the strands into four cables as described above in connection with FIG. 1, after which the several cables are twisted together to form the final bundle.
  • This latter bundle is wound up onto a suitable take-up reel.
  • each unit which for each cable section have a uniform twist length and twist direction are stored on the storing means 9 at each assembly, this storing means 9 being arranged within the space about which the pair of twisting frames 2 and 3 of each assembly rotates.
  • Each quad 26 is made up of the four strands 25 and is guided in each twisting assembly by the guide rollers 7 and 8 of the twisting frames 2 and 3 in the manner described above.
  • the accumulator roll 9 of each assembly of course cooperates in the manner described above with the guide rollers 13 for the twisted quads 26.
  • each quad 26 reaches an accumulator roll 9 it already has a double twist imparted thereto, and upon being Withdrawn from the storing means each quad will have a second double twist imparted thereto in the manner described above.
  • this method and apparatus of my invention has the advantage, as compared to known methods and apparatus, of requiring only half the number of revolutions and thus permitting the withdrawal speed to be increased. Also, as was pointed out above, instead of providing for the successive cable sections different directions of twist, it is possible to provide different numbers of revolutions for the twisting frames for the successive cable sections of each quad.
  • a guide assembly 41 which is provided with guide rollers 42 so that the several quads reach the twisting point of the rotary twisting frame 43 which is provided for the entire group of quads.
  • This rotary twisting frame 43 is composed primarily of a pair of storing rolls 44 and 45 around which the twisted quads are wound, and by periodically reversing the direction of rotation of the frame 43* a double twist is provided in the twisted bundle and then by way of guide rollers 46 the bundle is taken up onto a take-up reel 47 which has a stationary axis of rotation.
  • each cable section while being delivered to a storing means will be twisted in one way while the same cable section while being withdrawn from the storing means will be twisted in a different way, and during feeding of a given cable section to the storing means a double twist will be imparted thereto while during withdrawal of the same section from the storing means a second double twist is imparted thereto, so that in this way a fourfold twist is provided.
  • the several twisted quads 26, each of which is composed of the strands 25, are twisted in parallel and are immediately thereafter formed into the bundle 40.
  • a particularly favorable method and apparatus for manufacturing a cable bundle is provided, since the necessary twist of the strands 25 required for uncoupling the individual speaking circuits need only be determined during the manufacture of the cable, so that an expensive apparatus for maintaining the strands with different twists therein can be eliminated.
  • the individual strands 25 are respectively derived from reels 24, which respectively have stationary axes.
