Hook tape

The subject of the Eriinaimg is a hook tape for detachable Fastening of draperies, stretched wallpaper, theater backdrops, Upholstery covers or the like, which "avoids the disadvantages of the known means previously used for the same purpose".

There are known different types of holding means for substances, for the detachable attachment of saddlecloths, curtains, curtains and seating furniture covers, etc. to serve. One The commercially available snap fastener tape is a relatively simple solution to the fastening problem, with the one in the center line a tape to be fixedly attached with nails, pins or the like at equal intervals, for example the female snap fastener half ten are riveted, while the associated male Snap fastener parts at appropriate intervals on one Counter tape are attached, the one with the boring hanging? connected to exciting fabric.

Such snap fasteners allow a relatively quick attachment of the fabrics; but they show some mostly undesirable disadvantages, which are explained below:

With longer spans of the suspension and double hanging With snap fasteners, no height adjustment is possible. Snap fasteners usually made up of five parts

Ordering type are too expensive for the intended purpose, especially since the attachment of the two halves to the bands additional It is well known that the springs of the snap fasteners age considerably after prolonged use. Through this the holding force and the reliability of the connection between the bracket and the material can be inadmissible to decrease.

Another type of connection of fabrics with brackets provides a tape made of thermoplastic material, the one or several longitudinal grooves (egg-shaped band) in the corresponding can engage raised longitudinal webs of an opposing band. Undoubtedly, this connecting element is inexpensive to manufacture using the extrusion process and for some applications also sufficiently usable. On the other hand, however, it has several disadvantages, those of its universal application Set limits:

First of all, this connection is also the one already mentioned above Disadvantage of the lack of compensation option fully effective, since the longitudinal grooves clearly define the suspension height determine and with the decoration work; do not allow compensation. Experience has shown that the connection is unstable in the longitudinal direction of the eggs xmd webs, so that displacements between the suspension belt and the counter belt are possible, which lead to deficiencies in the suspension or tension of the fabric being able to lead. The connection is due to fold draperies Their longitudinal stiffness is of little use, especially since the additional

There is a risk of loosening the web from the groove, which also leads to considerable deficiencies in the decoration work can lead.

Finally, another solution to the problem posed is known, in which the principle of the Velcro connection Applies. In this case, for example, there is a receiving tape having the Velcro hooks and a loop knitted fabric on the fabric existing mating tape provided. This connection can be established quickly and also allows a sufficient one Height adjustment. For the given application, however, there remain some shortcomings that this system from the exclude universal applicability:

The Velcro fastener is too expensive for general use in decoration, as both the production of the Velcro tape as well as that of the loop knitted fabric a considerable require mechanical equipment and labor. The holding force of the Velcro elements is limited, which is special With heavy decorative fabrics or with mechanical tensile stress between the bracket and the fabric, there is uncertainty leads. Another disadvantage can be seen in the fact that Velcro connections, which - especially with upholstery covers - are exposed to large tension forces in the fiand zones, tend to gape, because in these areas the holding force of the Klettenzännchen and / or the loop fabric is not sufficient .

Joachim Jung February 10, 1969

The present invention therefore has the task of providing an easily detachable connection with a high load capacity create that avoids all of the aforementioned disadvantages.

It solves the problem in a simple and therefore more efficient manner in that it is the only special element that is primarily one Provides hook tape produced in the continuous machine operation, the hooks of which like thorns in the to be tensioned Decoration fabric itself or in an associated with this cheap, commercially available counter tape, z. B. fun band, intervene and thereby one in the tension and suspension direction Establish a practically non-detachable connection, which, however, is easily detachable in the opposite direction.

A hook tape suitable for this connection can easily be Execution z. B. be made in such a way that a. thin steel band with appropriate hardness and Deformation properties in the automatic punching machine with preferably several rows of pointed, hook-shaped, or thorn-shaped Notches is provided that protrude from the surface of the steel strip.

If necessary, the notches can be leaf-shaped and / or be formed corrugated so that after penetration into the opposing band of the unintentional separation of the connection to oppose a "limited resistance.

Among other things, the hook tape can also consist of a flexible

Joachim Jung February 10, 1969

Order plastic tape, ζ. B. of thermoplastic material that during the notching and deformation softens by the action of heat and hardens again when it cools down. There is also the possibility of to provide a thermoplastic tape with injection-molded bristles, which then z. B. in a rolling gear under Heat exposure to be bent in the shape of a hook and in this harden on cooling.

Another possibility is to use punched and / or bent parts made of stainless or with hooks or thorns rustproof material to be riveted or clamped on a textile tape in equidistant order or in a welding process to connect with a plastic tape. As a result, if the connection is very strong, a special good suppleness can be achieved, which is of considerable value for the decoration of folds.

The invention is therefore essentially characterized in that a primarily continuous working process equipped with hook-like or spike-like holding means oriented in the direction of support, with a commercially available one Mating tape, e.g. B. fleece tape, or the fabric to be tensioned itself firmly hooked in one direction, in the opposite direction but easily detachable metal, textile or plastic tape as a connecting element between a bracket and a decoration fabric or the like. Is provided.

Further details of the invention are in the accompanying Drawings shown, explained in the following description and defined in the subclaims. The drawings show the following:

1 shows an enlarged section of a steel band with notched hooks which can be nailed to;

2 shows a textile tape with clipped hook strips, from which the hooks are angled;

Fig. 3 is a double band of Xunststoffolien between which Hook strips are welded in, with their hooks through openings of a plastic band protrude through;

Fig. 4 shows a hook strip in which the hooks from a Tape material are sheared out;

5 shows a hook tape provided with hooks on both surfaces, in which the hooks on both surfaces are oriented in opposite directions.

In Fig. 1 an example of a hook tape 1 is shown in which the hooks 2 in an evenly spaced arrangement are attached. The number of hooks per unit area can of course be chosen differently from case to case will. If a high load-bearing capacity is required, strip material made of rustproof or

rustproof steel can be used. For special purposes other materials, e.g. B. an aluminum alloy or hardenable plastic, in Erage.

As can be seen from the figure, are leaf-shaped in the example formed hooks 2 notched out of the strip material by means of an automatic punching machine and in the same working process Shaped so that easy penetration of the hooks into the counter-band, not shown, is possible, loosening of the hooks on the other hand, it can only take place when a limited resistance is overcome. This intentional, but not in all ■ use cases The necessary complication of the loosening of the hooks from the mating tape can also, if desired, still through a corrugated design of the hooks are encouraged. In the simplest "case, however, a narrow, rectangular one is also sufficient ϊΌπη the pointed hook and your straight bend off the tape material.

The hook tape according to Flg. 1 can, as shown, be provided with additional holes that are used to nail the tape onto the stationary holding frame. With appropriately thin sheet steel and the use of suitable nails, the fastening can of course also be carried out by simply nailing through or stapling with staples.

The above-described hook tape is therefore a cheap mass-produced item to create. It can be certain in a certain way

Length dimensions are offered by the trade and can be easily cut to the desired lengths at the point of use. The material can be laid around all normally occurring curvatures without difficulty, so that it is suitable for fastening saddlecloths, decorations., theater sets and many other purposes can be used with considerable advantage, without the disadvantages mentioned above becoming effective.

Without changing anything in the principle of the invention, in the event that angled for a covering of hem corners Joints are required, and hook straps that are angled or bendable about a longitudinal axis can also be provided in which the hooks on both halves of the hook tape are directed towards the corner of the room.

Furthermore, in the case of a surface covering, a tight, wrinkle-free one To obtain a web of material, the mating tape connected to the fabric or the stationary receiving tape from a elastic band, e.g. B. rubber band, exist or be connected or combined with such. This will also when covering with inelastic fabrics in any case a hooking of the counter tape under tension.

In other applications, e.g. B, when hanging Draw curtains or the like, it is often desirable that the receiving tape also has a greater flexibility. TJm this too To realize, the hooks can be attached to partial strips

be, which in turn with a suitable machine at short mutual distances on a flexible textile or plastic tape are attached.

One such tape is in Pig. 2 shown. As can be seen therefrom, a textile tape 4 is provided as the carrier tape, on which strips 5 made of steel or some other suitable material are arranged at equal distances from one another and parallel to one another. In this case, the strips can be made from strip material in a continuous punching process and provided with bent hooks 5 &. Also in the punching process, the strips 5 are equipped with staple attachments 5b, by means of which they are firmly connected to the textile band 4 ^{in an S 1 oil tool.}

The Pig. 3 shows a further arrangement in which the aforementioned strips 5 (Pig * 2) are similar to strips 6 without holding classes as a hook carrier this. The Streifss sisd s ^ säsches sv / ei thermoplastic interconnected in the welding process Pollen 7 and 8 safely held. As the figure shows, the polie 7 is provided with cutouts 7a, which for The hooks 6a protruding from the strips 6 are used. The strips can, for example, be inserted into the pile 7 in a continuous operation by an automatic feeder will. They are then covered by the pile 8 in the same device. In one expedient with the feeding device combined HP welding machines are then both foils roughly in the dash-dotted lines

Areas welded together.

The design described above has the particular advantage that no mechanical clamping and riveting tools are needed and that the hook strip is made very simple can be. In addition, however, the double film gives the tape extremely good flexibility with a large one Strength ensured. Furthermore, in this embodiment, the nailing and tacking of the tape is due to the smooth contact surface very relieved.

In a modification of this embodiment, the two sub-bands 7 ii3iä. 8 can also be connected by gluing. You can then instead of plastic also consist of another suitable material.

Fig. 4- shows a very simple embodiment of the hook strips 9j which can be made from a narrow strip of material with an "inexpensive tool. The hooks 9a are sheared into the position shown during the tape feed, and immediately at the end of the shearing process cut the intended length of the strip from the tape.

Finally, FIG. 5 shows an embodiment Ί0 of the hook tape in which hooks 10a and 10b protrude from both surfaces, but which point in opposite transverse directions. Such a tape can serve as an intermediate layer between two fabric web ends ΛΛ and 12 and connect the webs to one another in the hanging or parallel arrangement. In which the

Joachim Jung February 10, 1969

For the sake of simplicity in the separating layer shown, 11 is a stationary suspended fabric web and 12 is the one with her hanging fabric to be connected.

Of course, you can, for example, avoid damage to avoid sensitive fabrics, also with this arrangement the fabric ends of 11 and 12 with commercially available counter straps be provided, in which the hooks of the hook tape 10 engage.

Such a hook tape serving as an intermediate layer can also be used to suspend or tension a web of material. It has the advantage that neither the holder nor the one to be suspended Fabric must be provided with other than commercially available bands. Just the intermediate layer of the hook tape outlook for the connection completely

Other uses of the hook tape arise, for example in the case of ribbons for bundling objects, for holding together rolls of carpet, for tying bandages, etc. as well as in Belts or "fasteners" in the clothing industry.

In this! Cases the hooks are oriented in the calibration Tung of the tape, and it may be Vann provided that only a short length of the hook tape is provided at the end of the binding, which engages at another place in themselves or in any affiliated reference belt -
