Definitions

  • the invention is directed to a weight cord of the type specified in the preamble of claim 1.
  • sheath-free pearl trains (DE-C-962 192), which have a series of lead pearls arranged one behind the other on a central carrying cord.
  • these weighting agents are sufficiently heavy in a small space and are sufficiently flexible for an undisturbed course of wrinkles because of the free spaces between them, the processing of the pearl trains is difficult because the lead pearls get stuck with their ends when inserting or incorporating the pearl train. This cannot be completely avoided if the ends of the individual lead beads are provided with inclined surfaces or curves for the purpose of a smooth introduction, especially since such special shaping of the individual lead beads requires more expensive production.
  • the invention has for its object to develop an easy to work on the curtain or the curtain weight cord of the type mentioned in the preamble of claim 1, which is characterized by particularly inexpensive manufacture without the weighting body must have a special end profile, the textile hose can be manufactured quickly. This is achieved by means of a weight cord and a method for its production, as characterized in claims 1 and 9, respectively.
  • the invention has recognized that the textile tube is easiest to manufacture in the spinning process.
  • the weight cord according to the invention is thus produced as a yarn bandage, the core of which is formed by the pearl train running in the axial center of the weight cord. Spinning fibers are wound around this thread core in a screw-like manner and initially form an outer textile tube made of twisted layers of spinning fibers.
  • the use of a so-called open friction friction spinning method, which according to the invention can be used for the production of weight cords, is very suitable for the invention.
  • staple fibers dissolved in an air stream are passed onto a pearl train, which, serving as a thread core, is used to wind the individual fibers.
  • the staple fibers also get into the free gaps between the adjacent weighting bodies, fill them and produce a graft which basically precludes the longitudinal movement of the weighting body in the tube.
  • the weight cord according to the invention is flexible. Because of this graft, a constriction on the surface of the textile hose is avoided.
  • the spun fibers also generate a high level of friction in the hose area, which also causes the weighting body to shift in the textile hose excludes.
  • the weight cord is smooth on the surface and allows trouble-free processing on the curtain.
  • a weight cord produced as such a twine is an extremely cheap and quick to manufacture product. Compared to the known textile braiding of hoses, the tenfold, even the hundredfold production speed is easily achieved. This results in particular from the manufacturing method described in claim 9.
  • the friction elements specified there can be designed as continuous endless belts, at least two of which are used as claimed in claim 10. Sieve drums have proven themselves as friction elements.
  • a consolidation of the wound fibers according to claim 11 is advantageous and, according to claim 12, different fibers can be processed in terms of material, length and winding when carrying out the method.
  • the spun fiber layer can also consist of different layers lying on top of one another, which are twisted differently from one another.
  • the consolidation of the outer spun fiber layer could additionally or alternatively also be produced, according to claim 5, by passing around one or more threads on the outside.
  • the threads can consist of monofilaments, filament yarns or spun yarns.
  • the threads can be guided around by simply winding or braiding, which can be carried out on a larger pitch, or the threads can also be connected to one another by means of stitches.
  • adhesives or weld connections according to claim 7, if at least one fiber component consists of thermoplastic material. Such a weldability could ultimately also serve to attach the finished weight cord to curtains or drapes, e.g. B. by ironing.
  • the weighting cord 10 is produced in the manner of a yarn in the spinning process and comprises a yarn core 11 made of a pearl train 12 of weighting bodies 13 arranged linearly one behind the other at a distance from one another and an outer spun fiber layer 14 made of individual fibers 15 of a web which are wound around the thread core 11 like a screw are.
  • the course of the turns is indicated in FIG. 1 by the thick dashed line 16.
  • the pearl train 12 has a special structure here because a supporting cord 18 is used to hold the weighting body 13 at a desired distance 17, which is guided through a central bore through the weighting body 13.
  • the weighting body 13 here consists of sections of a predetermined length 19, the ends 20 of which can easily be formed from the resulting separating cuts without special profiling, which enables the pearl train 12 to be produced easily.
  • the individual fibers 15 After the weighting cord 10 has been produced as a yarn in a spinning process, the individual fibers 15 also come to lie in the free gap 21 between adjacent weighting bodies 13 and form a graft there.
  • the spun fiber layer 14 thus forms in the weighting cord according to the invention a hose with inward plugs between the weighting bodies 13, which preclude a longitudinal displacement of the weighting body in the sense of the arrows 22 indicated in FIG. 1 on the central carrying cord 18.
  • the spun fiber layer 14 can be formed from fibers of any material and of any length, which are stranded together in a thread-like manner around the thread core 11. Different materials can be used in layers in the given spun fiber layer 14 without this significantly increasing the cost of manufacturing the weight cord 10 according to the invention. So how, through that 2, an inner layer 23 can be formed from cheaper fiber material, without this affecting the function and appearance of the outer layer 24 formed from more suitable fiber material.
  • a pearl train 12 could of course also be introduced into the interior of the yarn-like weight cord 10 according to the invention, where the individual weight bodies 13 are not connected by a carrying cord 18; z. B. a different type of carrier, e.g. B.
  • an adhesive tape can be used on which the individual weighting body 13 are at the desired distance from each other.
  • a prepared bead train 12 is assumed, which is guided into the area of a gusset between two closely spaced screen drums 26, 27 in the direction of the drum axes, as can be seen from the sectional view of FIG. 3.
  • the two screening drums 26, 27 are expediently moved in the same direction of rotation.
  • These sieve drums 26, 27 belong to a device 30 of a so-called open-end friction spinning, where, as is not shown in FIG. 3, a fiber sliver or a fiber sliver is dissolved in a drafting system and fed through a channel 31 to the gusset area 25 mentioned will.
  • an air flow is expediently used as the carrier medium, which flows in the direction of the flow arrows 32, 33 in the gusset area 25 into the interior of the two sieve drums 26, 27 and thereby deposits the separated fibers 15 on the suction surface of the two sieve drums 26, 27.
  • the rotation could also be maintained, which would lead to a surface hardening.
  • the flow 32, 33 of the air loaded with individual fibers 15 on the drums 26, 27 comes about from the fact that, as shown in FIG. 3, suction tubes 36, 37 are present in the interior of the drum, the tube openings 38, 39 of which are directed towards the gusset region 25 mentioned.

Abstract

Afin de permettre un façonnage sans obstacles de rideaux, on utilise non seulement un cordon de perles (12) composé de poids (13) espacés, mais on enveloppe ce cordon de perles (12) dans une gaine textile (14) qui assure une surface (40) essentiellement continue de cordon. Afin de produire le cordon de chargement (10) de façon économique, il est proposé de le former comme un ensemble de fils par un procédé de filage; le cordon de perles forme une âme axiale (11) du fil, les fils textiles entourent l'âme et s'ordonnent autour de celle-ci de manière à ressembler à un tuyau (14).
