Definitions

  • the invention relates to a stranding for a longitudinally watertight Message cable according to the preamble of claim 1 and a method for producing a stranding for a longitudinally watertight Communication cable according to the preamble of claim 7.
  • a star quad is known in which as the central Blind element is a cord made of paper is used.
  • the star quad against Longitudinal water is tight, the cord is one with the access of water provided swelling powder.
  • From DE-PS 33 06 077 is a multi-strand stranding for a longitudinally watertight communication cable with a braided Plastic carrier thread known as the central blind artery, on its entire Surface is flocked with short threads so that they stand upright and Thus, there is a velvet-like yarn as a dummy.
  • the tanned Plastic carrier yarn be provided with a powder which in presence of water increases its volume.
  • a communications cable made using this method Stranding units is absolutely longitudinally watertight and consists of the prescribed Tests for longitudinal water-tightness.
  • the present invention is the The object of the invention is to provide a stranding which is essential is cheaper to produce.
  • FIG. 1 shows a section through a stranding according to the teachings of the invention.
  • FIG. 2 shows a side view of a device with which the method according to FIG the teaching of the invention is feasible.
  • FIG. 1 shows a star quad constructed of four wires. Every vein has an electrical conductor 1 and a layer 2 of an insulating z. As polyethylene.
  • the four wires are stranded together to determine the transmission characteristics of the Sternvierers to improve.
  • a plurality of the star quads shown in FIG. 1 become one Telecommunications cable summarized, with the star quads to each other and bundles are stranded.
  • the four veins are sheathed by a band 3 whose one band edge area 3a in the gusset formed by the four veins in the interior of the star quad protrudes.
  • the band 3 consists of a swelling with the passage of water Material and seals in case of ingress of water in the telecommunication cable the Gusset area and the gussets located between the wires outside.
  • the material is a swellable nonwoven. However, it has proved particularly advantageous a proven in cable technology insulating paper proven.
  • the band 3 extends over the entire length of the star quad.
  • the cores 4, 5, 6 and 7 are continuous by the coils 8, 9, 10 and 11 withdrawn and fed to a nipple 12.
  • the inner diameter of the nipple 12 is dimensioned so that each of the wires 4 to 7 touched the hole. After exiting the nipple 12, the wires 4 to 7 wound on a drum 13, in the direction of the arrow 14 of a motor, not shown, is driven.
  • the drum 13 is rotated about the axis x, whereby the four wires stranded with each other (see arrow 15).
  • a shaping device 16 is arranged before the nipple 12. This Forming device 16 is supplied from a coil 17 withdrawn band 3, in which an edge region 3a of the band 3 is folded by about 90 °.
  • the wires are fed to the nipple 12 so that the edge region 3a comes to lie between two wires, as shown in the figure 1.
  • the band 3 is in front of the nipple 12 or in the nipple 12th wrapped around the wire bundle. The band 3 thus participates in the stranding.
