Description

The invention relates to a Drapierband for a sheet such as a curtain, a curtain od. Like., And a method for producing such Drapierbandes. Such Drapierbänder be used in particular in the field of interior decoration. They are used in fabrics, such as curtains or curtains on the one hand to complain the material of the fabric, so that it is not blown in a draft, but on the other hand also to allow a nice uniform waveform of the fabric.

Such Drapierband the type mentioned describes, for example, the DE 36 11 313 C2 , The Drapierband described there consists of arranged on a carrying cord weighting bodies, such as lead beads, which are then enclosed by a textile tube. This enclosing is particularly necessary when using lead beads as weighting bodies in order to make the dark color of the lead not visible through the possibly translucent material of the sheet. In addition, it should also be avoided that persons come into skin contact with the lead beads or children put these in the mouth. However, the use of the hose is disadvantageous because this results in increased costs. The raw material lead has also become increasingly expensive in recent years, although its use can be regarded as dubious from an environmental point of view. So here is an alternative to find.

The DE 201 00 457 U1 now proposes to use plastic sections as weighting elements. In one embodiment, it is proposed to separate the plastic sections completely from each other and then in turn introduce into a tube to obtain the desired Drapierband. The handling of the loose plastic sections is However, difficult and feasible only with a high mechanical or manual effort. Further embodiments provide that the plastic sections are still connected by bridges, which consist of the same material as the plastic sections themselves. Although these are easier to handle but relatively stiff, so that the desired wave wrinkles on the fabric can not be formed sufficiently well. The DE 1283455 B1 discloses a draping belt having the features of the preamble of claim 1 (see embodiment in Fig. 10). The object of the invention is therefore to provide a Drapierband which avoids the aforementioned disadvantages and which is simple and inexpensive to manufacture and also has the desired Drapierfähigkeit. This object is solved by the characterizing features of claim 1, which has the following special significance.

The Drapierband consists of plastic sections, which are arranged on a continuous core. The soul in turn consists of two concentrically arranged parts which are at least slightly displaceable in the axial direction to each other. The plastic sections are fixed on the outer part of the soul and go with this preferably a mechanical connection. By this arrangement, one obtains a Drapierband which has sufficient Drapierfähigkeit and which does not need a hose which sheathed the plastic sections, since the color of the plastic sections and the soul is quasi freely selectable. It is thus also possible to provide draping ribbons in virtually any color. The production of Drapierbandes is significantly cheaper because it can be dispensed with the hose and the plastic is cheaper to manufacture than the lead previously used. As a result of the two-part design of the core, the plastic sections on the core can also be shaped like a pearl cord, which also simplifies the production process, as will be explained in more detail below.

In order to produce the Drapierband invention, it is possible to first encase the two-part soul with a plastic, whereby a plastic sheath is formed, which is then divided into individual plastic sections. In order to obtain a shape of Drapierbandes in which the individual plastic sections are spaced from each other, the plastic shell is chopped by means of a punching blade, wherein the plastic sections including the outer part of the soul are slightly displaced relative to the inner part of the soul. This results in the already mentioned plastic sections, which are spaced apart and form a kind of string of pearls. Of course, it is also possible to provide several punching blades.

It is possible that the two parts of the soul of Drapierbandes made of the same material. It must then only be ensured that the two parts do not enter into a fixed connection with each other, but that the parts can still be at least slightly offset from each other.

It is also possible that the two parts of the soul consist of different materials. These may be of a similar type, for example two plastics or completely different, for example a plastic, a natural fiber, such as flax, hemp, cotton, silk or the like or even a plastic and a metal, a natural substance and a metal or the like. In particular embodiments of this type, the core is formed as a core yarn as a twisting thread or as a bell wire.

In order to make the plastic sections or the flexurally elastic body heavier and thus to achieve better draping properties, a thermoplastic or thermosetting material provided with fillers is used as the material for the plastic sections, it also being possible to use mixtures of these materials. As fillers, a wide variety of materials can be used, but especially barium sulphite, Ceramic dust and / or sand. Other materials or a mixture of the above are possible.

It is possible that the Drapierband has a planar extent, wherein the plastic sections are arranged both behind one another and next to each other. Such draping ribbons can then serve different purposes. In the formation of the plastic sections one behind the other and next to each other several souls are provided in Drapierband, each of the plastic sections is arranged on a soul.

In order to divide the plastic sheath formed around the soul in the production of Drapierbandes in several plastic sections, a punching knife is preferably used, which has two mutually opposite punching wheels with preferably conical teeth. This has been proven to form the plastic sections of the plastic jacket. In addition, such punching wheels are known. The method of dividing the plastic sheath into the individual plastic sections is simple and inexpensive by means of the punching blade.

Further embodiments and modifications of the invention will become apparent from the following description, the dependent claims and the drawings. In the figures, the subject matter is shown in two embodiments. Show it:

an inventive Drapierband in section according to the section III-III Fig. 2

Fig. 1 shows a first embodiment of a Drapierbandes 10 with a flexurally elastic body 11. This consists of arranged on a core 20 plastic portions 12 which are spaced apart. The core 20 consists of an inner part 21 and an outer part 22, which are mutually displaceable 23 in the axial direction 13. The crowd of plastic sections 12 shown here is completely radially the soul 20 circumferentially 16 divided. This has the advantage that the Drapierband 10 in any direction has the same bending elastic properties and thus the same Drapierfähigkeit.

Another embodiment is in Fig. 2 shown. Here too, a group of plastic sections 12 is arranged on a core 20 in order to form the flexurally elastic body 11 of the draping strip 10. However, the plastic sections 12 shown here are only indicated in two planes separated by 14 and 15 from each other. As a result, the flexurally elastic body 11 of the draping belt 10 offers different draping properties depending on the angle at which it is installed. For example, in order to produce a uniform wave fall in a curtain, the draping belt 10 is turned off Fig. 2 installed so that the in Fig. 2 shown in plan view of the Drapierband 10 results.

To a drape 10 according to Fig. 2 To manufacture, the plastic sheath in the two levels 14 and 15 must be divided to form the plastic sections 12. If, however, the plastic sheath is completely radially divided around the core 20, then the flexurally elastic body 11 is obtained Fig. 1 ,

Fig. 3 now shows the internal structure of a plastic portion 12 according to the section III-III in Fig. 2 , It can be seen that the core 20 is composed of an inner 21 and an outer part 22. On this outer part 22 of the actual plastic section 12 is arranged. The material of the plastic portion 12 is on the outer part 22 of the soul 20th established. Preferably, he goes with the outer part 22 a mechanical connection. This can be done, for example, that the material of the plastic portion 12 during the attachment of the plastic sheath around the soul 20 merges with the outer part 22 of the soul 20 something. Of course, other possibilities are conceivable, the plastic sections 12 set on the outer part 22 of the soul 20, such as chemical reactions or mechanical connections.
