Definitions

  • Weighting cord for curtains, drapes or the like and process for their production are Weighting cord for curtains, drapes or the like and process for their production
  • the invention is directed to a weight cord of the type specified in the preamble of claim 1, as is known from DE-AS 11 89 686.
  • these weighting means are sufficiently heavy in a small space and are sufficiently flexible for an undisturbed course of the wrinkles because of the free spaces between them, the processing of the pearl trains prepares them
  • the weighting cords of the present type avoid the aforementioned disadvantages by means of a hose which surrounds the pearl train (DE-AS 11 89 686).
  • the hose bridges the free distances between the weighting bodies without appreciably hindering the flexibility of the beading o during the formation of folds and creates a substantially shoulder-free cord surface, which allows the weighting cord to be worked in smoothly on the curtain or the cord pulled into the edge area the curtain enables.
  • a hose in particular tightly surrounding the pearl train, secures the desired spacing of the weighting bodies from one another and precludes their inadvertent shifting during processing on the curtain or when using the curtain.
  • the outer textile character of such weighting cords is also favorable, because they adapt better to the curtain fitted with them.
  • the production of a textile tube for weighting cords of the generic type is very complex. 5
  • the textile tube is namely achieved by crossing threads in a braiding process, where the supply bobbins, which only take up a limited length of the individual threads, are intertwined with one another on a complicated braiding machine in accordance with the desired braiding pattern . Even with braiding machines that work very quickly and are therefore prone to failure, the textile hose can only be produced at a few centimeters per minute. This is relatively high Price of the weighting cords.
  • the object of the invention is to develop a weighting cord of the generic type which is easy to process on the curtain or the curtain and which is characterized by particularly inexpensive manufacture in that the lead beads need not have a special end profile and the textile tube itself can be produced quickly.
  • the invention recognized for the first time that the textile, hose-like covering can be produced in the simplest and fastest way as a yarn in a spinning process.
  • a pearl train is used, which is used as the core element for the yarn production, in that the individual fibers of a web are placed around this core element, which together with the pearl train lead to a yarn assembly, that is to say a spun thread.
  • the use of the so-called open-end friction spinning has proven to be very suitable for the invention (cf.
  • Weighting cords of the generic type can be used, where in a 5 air stream spun fibers according to the invention are passed onto a pearl train which, serving as a thread core, is used to wind with single fibers.
  • the fibers wrapped around the bead train now form a perfect textile tube, which bridges the gaps between adjacent weighting bodies and thereby creates a cord surface that is essentially free of shoulder. This means that the weighting cord on the curtain or curtain can be processed without any problems.
  • the spun fibers on the surface of the composite yarn according to the invention sufficiently increase the friction compared to the curtain equipped with this cord, which is why the cord also has to be displaced in the edge of the curtain holding it when the curtain is used as intended or when the curtain is drawn in or pulled out Windows or doors are not to be feared.
  • the production of the weighting cord according to the invention equipped with a textile tube as "yarn" is characterized by an extremely cheap and fast production. As practice has shown, it is easily possible to achieve ten times and even a hundred times the production speeds of the invention compared to the known textile braiding process. This is achieved in particular in the special manufacturing method belonging to the invention, which is described in more detail in the claim.
  • Circulating endless belts can be used as friction elements, of which at least 5 two are used. In practice, two co-rotating sieve drums have proven themselves as friction elements, in the gusset area of which the point of contact with the pearl train lies and where the transport medium loaded with the individual fibers of the web is blown through.
  • the weighting cord produced in this way is already sufficiently firm with its outer spun fiber layer.
  • the individual fibers hang even without any particular twisting the outer spun fiber layers are sufficiently tight to each other; their ends are hooked together.
  • the weight cord according to the invention acts externally like a cotton cord.
  • a consolidation of the position results from an additional twisting, which can be achieved by stranding the weight cord obtained according to the invention.
  • additional or alternatively other measures can be used, e.g. Routing one or more threads on the outside. These threads can be made of monofilament, fila or spun yarn. The threads can be guided around by simply winding or braiding, which could be done on a larger pitch, or by knitting. Adhesives could also be used for solidification or welding attachments could be carried out if at least one material component of the fibers consists of thermoplastic material. Such a weldability can finally also be used to attach the finished weight cord to curtains or curtains, e.g. by ironing on.
  • the hose of the weight cord according to the invention can be adapted to the appearance of the curtain or curtain at any time with regard to material and color.
  • it is sufficient here to design only the outermost partial layer of the hose in this sense because, according to a further proposal of the invention, the hose of the weight cord consists of a plurality of layers lying one on top of the other, which layers are made of different fiber material. In this way, a further reduction in the material price can be achieved, because cheaper fiber materials can be used in the inner zones 5, which are not visible from the outside, than in the later outer layers. In this way, a pattern on the weight cord can also be achieved.
  • this can be achieved simply by blowing fibers of different materials and / or different lengths and / or different compositions along the contact path of the pearl train on the circumferential friction elements. This is because the inner layers of the spun fiber layer are formed in the initial section of this contact path, while the outermost layers are formed in the last piece of this contact path. This allows the inner
  • FIG. 2 shows a cross-sectional view through the weighting cord according to the invention along the section line II-II of FIGS. 1 and 5, which is enlarged to an even greater extent than FIG. 1
  • FIG. 3 shows a schematic representation of a device for producing the weighting cord according to the invention.
  • the weighting cord lo according to the invention is produced in the manner of a yarn in a spinning process and comprises a core of yarn 11 made of a pearl train 12 made of weighting bodies 13 arranged linearly one behind the other and made of an outer spun fiber layer 14 individual fibers 15 a. Spun, which are wound around the thread core 11 like a screw. The course of the winding 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 led through a central bore through the weighting body 13.
  • the weighting bodies 13 here consist of sections of a predetermined length 19, the ends 20 of which can simply be formed from the separating cuts which occur, without any special profiling, which enables the pearl train 12 to be produced easily.
  • the individual fibers 15 o also lie in the free gap 21 between adjacent weighting bodies 13 and form a graft there.
  • the spun fiber layer 14 in the weight cord according to the invention thus forms a tube with inward plugs between the weight bodies 13, which preclude a longitudinal displacement of the weight bodies in the sense of the arrows 22 on the central carrying cord 18 indicated in FIG. 1.
  • 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 affecting the manufacture of the weight cord according to the invention significantly more expensive. Thus, as illustrated by the dash-dotted line in FIG. 2, an inner layer 23 of cheaper fiber material can be formed without this affecting the function and appearance of the outer layer 24 made of more suitable fiber material.
  • a pearl train 12 could of course also be introduced into the interior of the yarn-like weighting cord lo, according to the invention, where the individual weighting bodies 13 are not connected by a carrying cord 18; for example, a different type of carrier, for example an adhesive tape, on which the individual weighting bodies 13 are located at the desired distance from one another could be used.
  • a different type of carrier for example an adhesive tape
  • a prepared bead train 12 is assumed, which is guided into the region of a gusset between two closely spaced screening drums 26, 27 in the running direction of the drum axes, as can be seen from the sectional view of FIG. 3.
  • the two sieve drums 26, 27 are expediently moved in the same direction of rotation.
  • These sieve drums 26, 27 belong to a device 3o 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 o and through a channel 31 to the one mentioned Gusset area 25 are supplied.
  • an air flow is expediently used as the carrier medium, which flows in the direction of the flow arrows 32, 33 shown in the gusset region 25 into the interior of the two sieve drums 26, 27 and .
  • suction tubes 36, 37 are present in the interior of the drum, the tube openings 38, 39 of which are directed towards the gusset area 5 25 .

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).
