Definitions

  • a novel arrangement for screening each of a plurality of electric cable components from one another and laying up the screened cable components, so formed, into a cable in one continuous operation The individual 'cable components are simultaneously screened from one another by longitudinally applying a common tape of electrically conducting material to each individual insulated component, and laying up the plurality of screened cable components.
  • FIG. 1 shows, schematically, a known laying-up arrangement
  • FIG. 2 shows, schematically, an arrangement for screening and laying-up according to an embodiment Ition of FIG. taken at five positions along its length;
  • FIG. 7 shows the various cross-sections a single wide metallic tape has before, during and after passing through the screenforming device of FIGS. 3 to 6.
  • FIG. 1 A basic prior art arrangement for performing the laying up of the screened components is shown in FIG. 1.
  • the arrangement basically comprises a rotatable structure 1 on which are provided means, for example pintles 2, for mounting reels 3 of the previously screened cable components 4 so that the reels 3 are rotatable about their own axes, in order to permit the cable components on them to be unwound.
  • means for example pintles 2
  • reels 3 for example pintles 2
  • the reels 3 are rotatable about their own axes, in order to permit the cable components on them to be unwound.
  • only three reels have been shown in the drawing, although more than this number may of course be used.
  • a take-up reel (not shown), possibly by way of other manufacturing stages, for example helical tape applicators and sheath extruders.
  • the take-up reel and the structure 1 By rotating the take-up reel and the structure 1, the screened cable components 4 are pulled off their reels 3 and laid up together to form a cable 6.
  • the length of lay is dependent on the take-up rate and the rotational speed of the structure 1.
  • the forming die 5 serves to form the laid up components into a cable 6 with a predetermined cross-section.
  • FIG. 2 there is shown the basic arrangement of apparatus for use in accordance with the screening and laying-up method of the present invention.
  • This arrangement comprises a rotatable structure 7 on which is provided means, for example pintles 8, for rotatably mounting reels 9 of unscreened cable components 10, similar to those in the arrangement for FIG. 1.
  • the reel 11 is mounted so that it is rotatable about its own axis for unwinding the tape 12.
  • a device 13 Rigidly mounted on the end of the structure 7 adjacent a forming die 25 is a device 13 by means of which the wide metallic tape 12 is longitudinally formed at least partially around each of the cable components 10, while a take-up reel (not shown) pulls them off their respective reels, in order to produce screened components 14.
  • laying up of the screened cable components 14 into a cable 15 is achieved by rotation of the structure 7, which includes the device 13.
  • the device 13 for wrapping the tapes around the cable components can take many forms, but it will basically comprise a number of similar forming tools, the same number of tools as there are cable components, each one of which applies a portion of the wide tape to a separate one of the cable components.
  • the forming tools can, for example, be forming dies, systems of rollers or brushes.
  • FIGS. 3 to 6 The basic structure of a suitable type of forming device die is shown in FIGS. 3 to 6.
  • This device basically comprises a substantially truncated-conical portion 16, in which grooves 17 are provided.
  • Each of the grooves 17 is associated with a separate one of the cable components 10 and its associated portion of the wide tape 12, so that in the form shown in FIG. 3 there are 8 forming tools in one structure.
  • the grooves 17 increase in width and decrease in depth in the direction away from the apex of the cone portion 16.
  • a tape guide member 18 H6. 5 which has a similar shape to grooves 17, as can be seen from FIG. 6 which shows the variation in cross section of the member 18 between its left and right-hand ends.
  • the guide members 18 are mounted in the grooves 17 so that a slot is provided between the members 18 and the grooves 17.
  • the mounting can be achieved by means, for example, of a collar 19 and screws 20, but a gap must be left between the collar and the walls between the grooves in order that the wide tape may be continuous between adjacent grooves.
  • a wide flat metallic tape is inserted simultaneously into each of the slots at the right hand end of the grooves 17 and pushed through the slots then it will be formed into a star-shaped member 22 having radial convolutions forming longitudinal channels along the tape, as shown in FIG. 7.
  • An insulated cable component can be dropped into each recess or channel between two adjacent arms of the star-shaped member, if the component is directed along a line similar to line 24 of FIG. 5. Further forming of the metallic tape around the insulated cable conductors can then take place. This may be affected by means of rotation of the structure 7 and the forming device 13 during the laying-up process.
  • the method and apparatus using the forming die etc could alternatively be used with a separate narrow metallic screening tape for each cable component, that is a separate tape for each groove 17 of the die.
  • a separate reel, of tape would then have to be provided for each reel of cable components.
  • the forming die may form the narrow tape into a V- shape and the remaining formation may occur during laying-up, or the forming die may form the tape into a tubular member, with a longitudinal seam, around the cable component.
  • a method of screening each of a plurality of elec- 4 tric cable components from one another and laying up the screened cable components, so formed, into a cable in one continuous operation comprising the steps of feeding a plurality of individual cable components and an electrically conducting screening material along a longitudinal path, forming a plurality of radial convolutions in said material, guiding said cable components into said convolutions, simultaneously screening the individual cable components from one another by longitudinally applying said material to each individual cable component at the same time, and laying up the plurality of screened cable components.
  • each cable component is screened from the others by a single metallic tape and a forming tool having a plurality of radial convolutions, passing said tape through said tool to form said plurality of convolutions in said tape for receiving respective cable components, and wrapping said tape about said cable components.
  • Apparatus for simultaneously screening each of a plurality of electric cable components from one another with longitudinally applied electrically conducting material and laying up the pluralityof screened cable components, so formed, in one continuous opera- I tion comprising a rotatable frame, a plurality of cable component supply reels carried on said frame, a supply reel of electrically conducting material, all of said supply reels being freely-rotatable about their own axes, means for forming a plurality of radial convolutions in said material, means for guiding the cable components into the convolutions, each convolution being adapted to accommodate a respective cable component, and take-up means for pulling the cable components through said forming means to wrap said material about said cable components.
