Hook couplings have been known for several years, comprising two flexible parts provided with hook couplings and pressed against each other.

For example, Swiss Patent Publication No. 339,155 discloses such a device in which the hook connecting members of the second part are loops and the hook connecting members of the second part are hooks. Hook connection members are also known which comprise two identical parts, each part having a plurality of carpet-forming loops of a certain thickness and a plurality of hooks. Loop and hook members are usually made by weaving. They have some use, especially in the clothing industry (for closing clothes), in the furniture industry (seat covers, carpet fastening), in medicine (bonding) and the like.

Also known are hook connection members, i.e. suspension members, which comprise two parts which penetrate each other's holidays and which are made of plastic. metal. For this purpose, a hook connection member, i.e. a suspension member, has previously been proposed, the base of which is of synthetic material and which has on its surface a very large number of closely spaced projections intended to engage the projections of another similar member. These projections may be sponge-shaped or hooks made of the same material as the substrate, and the members may be formed, for example, by injecting a synthetic material into a mold.

Metal hook-up members, i.e. suspension members, which have also been called clamp-hook members, have also been proposed. Such a member consists of two parts, one with a very large number of metal hooks and the other with many metal loops, the hooks and loops being attached to the strips of plastic material.

These members made of plastic or metal have good adhesion resistance, but are generally less flexible than those made by weaving or knitting and are therefore used for other purposes, for example to attach decorative panels in place or to attach objects to various vehicles.

A common feature of all these proposed or used bodies is that their shape cannot be flexibly changed under different possible conditions, although they are often very flexible. For many applications today, such resilient formability is not only desirable but also often necessary, as otherwise such hook joints, or suspension members, may be unusable. In the garment industry, for example, stretchable textiles are often processed, and if such known hook-and-loop members are used to close them, the point of the fabric to which the hook-and-loop members are attached often loses its resilient properties. This is the reason why such hook joints, i.e. suspension members, have been used.

relatively little, namely in underwear, corsets, various medical applications and the like.

One object of the present invention is to provide a hook connection device, i.e. a closing device, which 3 59332 can also be subjected to considerable elastic deformations and in particular to longitudinal tensile stresses without detachment of the hook joints.

For this purpose, the fastener according to the present invention is characterized in that the bases of the locking elements have elastic warp yarns and that both bases have inelastic warp yarns in addition to the elastic warp yarns, the non-elastic warp yarns being arranged in excess, i.e. in a sak shape, on the substrate so that they can be straightened and the length increased in the stretching direction as the strip is extended.

Without any detrimental effect on the hook joint effect, it may be possible in such a flexible member to give it a tensile stress as a result of the corresponding elongation of the device. Tensile stresses in two different directions can be applied either to two superimposed and hooked substrates or also to one substrate being acted upon by traction in one direction and the other in the opposite direction. When the elastic properties of both bases are similar to each other, the latter stretches equally when subjected to tensile stress, and the hook-and-joint members adhering to each other do not receive any possible displacement with respect to each other. In all such cases, the hook joint is perfectly preserved.

When the hook connection device according to the present invention is used to fasten two flexible fabrics to each other, it is possible, when the fabric is subjected to tensile stress, to stretch the hook connection member simultaneously with the fabric. In this way, a flexible attachment or closure of the garment to another garment is provided. If, on the other hand, both substrates have different elastic properties, the deviation must always be chosen so that the average elasticity of the hook-and-loop device, i.e. the closing device, is sufficient to withstand the stresses applied to it in such special cases.

Some embodiments of a hook connection device according to the present invention are shown in the following examples and the accompanying drawings.

EXAMPLE I

a) X-hook connection member or hanging member (Fig. 1) In this embodiment, a hook-forming strip is made by making. a substrate having a warp of multifilament nylon yarn 1-12 and having a weft of multifilament nylon yarn 13 and yarns 1U of natural or artificial elastic material. The weft yarns 2-3, 5-6, 3-9 and 11-12 are arranged in two ends one on top of the other, and the flexible yarn 1h is arranged to pass between these weft yarn pairs and yarns 1, 4, 7 and 10. The thionic nylon warp yarns 13 are arranged to run tortuously between the weft yarns 1, 2> * +, 5, 7, 9, 10 and 11, etc. The hooks 15, 16, 17 and 18 are made by means of the monofilament yarns still present in the warp, which are The first such additional connecting wire 19 forms a hook 15 by means of a truncated loop and then passes under its two weft threads 2 and 3 and then over the weft thread 4, whereby a hook 17 is formed again by the truncated loop when it is passed between the two weft threads 5 and 6. under. After forming the hook? .7 ku.lj.ee the monofilament yarn 19 under the weft yarns 8 and 9, on top of the weft yarn 10 and then again forms a hook (not shown in the figure) after passing under the weft yarns 11 and '12. The second yk-3 .lilU i tU ill'Jll Id-iUvci 1. ua then passes over the weft yarn 1 then under the two weft yarns 2 and 3 and forms a hook 15. It then passes under the two weft yarns 5 and 6, over the weft yarn 7 and forms hook 18 as it has passed under the weft yarns 8 and 9.

After weaving, the hook strips are heat treated so that the base and the monofilament yarns 19 are completely attached to each other, which after cutting become hooks 16, 16, 17, 18 ... The temperature and processing time used in this treatment depend on the yarn used. When using this treatment, it is usually necessary to seal the strip without, however, stretching it so that it becomes completely smooth. In order to maintain good flexibility and to improve and firmly attach the strip body to the underlying fabric, the loops which have become hooks 15-10 after cutting are finished by coating the strip with a coating of flexible flexibility, for example latex.

6,59332

When finished, the strip is stretched with a certain force, which must be such that it does not stretch during the coating and drying steps. The finishing layer, which is almost completely cured in this treatment, forms a sufficiently strong connection to the monofilament hooks and allows the strip to stretch and recover without the hooks or fabric changing shape. In order to cut the monofilament loops 19 to form hooks, the strip is tightened so that the loops can be cut without difficulty.

The hook strip shown in Figure 1 can be stretched 100%, so that its length is doubled in this way. Examining Fig. 1, it is seen that the elastic yarn 14 is stretched when the strip is stretched. However, the base yarns 13 and also the monofilament yarns 19, which are neither elastic nor consequently stretchable, are tortuously located between the weft yarns 1-12 of the substrate. increasing in the direction of stretching, i.e. also in the direction of the deformation of the hook connecting member, i.e. the suspension member or the closing member.

b) Hook connection member (Figure 2)

The base of the loop member is woven in the same way as the base of the hook connection member or suspension member according to Fig. 1. The loop strip is made by making a substrate comprising multifilament nylon weft yarns 20-28 and weft yarns comprising multifilament nylon yarns 29, 29a and 29b, and elastic yarns 30 made from natural or artificial materials.

The elastic yarns 30 pass under the weft yarn 20, over the weft yarn 21, below the following weft yarns 22 and 23, which are located close to each other, over the weft yarn 24, etc. The warp yarns 29 and 29a of the substrate meander the belonging yarn 29b is also tortuously located in the vicinity of the weft yarns 20-28 but always passes so that it passes two adjacent weft yarns 22, 23, 24, 25, etc. The loops 31-36 are formed by additional warp yarns 37, 37a and 37b, which are staple fiber yarns and are arranged tortuously between the warp yarns 20-28 and the tightening elastic yarns 30.

7 59332

As with the hook strip, this strip is also subjected to a heat treatment, whereby loops 31-36 formed of monofilament yarns 37, 37a, 37b and a substrate formed of warp yarns 20-28 and weft yarns 29, 29a, 29b and 30 are finished by applying a flexible the finishing layer on the rear surface of the base as well as on the rear surface of the base of the hook connection member, i.e. the flexibility properties of the loop base described above, may be the same or different from the hook connection elements not i.e. the properties of the suspension base described in connection with 1. Since the elastic wire is able to stretch and s k. Α 1.; I ... il an ^ at are tortuous, the base of the loop connection member can also stretch 100¾ for the same reasons as the base of the hook connection member, i.e. the suspension 1 iii. En. When the base of the hook members and the base of the loop members are at rest with each other and are then subjected to tension when subjected to tensile stress, they stretch according to the tensile stress applied to them and the other interlocking loops and hooks remain in substantially the same positions with respect to each other without being adversely affected by them. to each other »1.- · r -r Τ '· -. O a. J Li_ji \ ivi \ X li

The structures described in Example I have flexible properties in only one direction, i. in the direction of the warp, which is perfectly adequate for ordinary purposes. If it is possible, it is also possible for those skilled in the art to carry out weaving as well by using elastic weft yarns or weft yarns which meander past the warp yarns, thus providing elastic properties in two directions. Such an embodiment is schematically shown in Figures 3, 4 and 5, where arrows F denote longitudinal tensile stresses, while arrows denote transverse tensile stresses.

This embodiment also includes a base 38 with suitable hook-connected members, i.e. loops 39, and a base 40 with suitable hook members 41.

In the same way, it is also possible to manufacture hook-coupling devices, i.e. suspension devices and closing devices, which have flexible properties in several different directions.

EXAMPLE III

Tass · ", the example describes an embodiment of a hook connection member, i.e. a suspension member, which has a strip width of 30 mm and which has good longitudinal flexibility.

a) Element to be joined by hooks: (Figures 6, 7 and 8) In this embodiment, the double warp base comprises a first warp with 160 multifilament polyamide yarns having a strength of 140 aenieriM, 600 T / Z to 400 T / S, and a second warp comprising 37 synthetic rubber threads, 2300 m / kg.

The splicing thread weave consists of 3 5 single-stranded polyamide yarns with a thickness of 0.18 mm. The weft yarn is a multifilament polyamide yarn with a thickness of 200 denier, 200 T / Z normal. In this embodiment, the entire strip warp system is as follows:

Looking at the diagram in Figure 1, it is found that in order to obtain a satisfactory product when stretched, it is necessary to form loops of monofilament yarn by placing them in at least two polyamide backing fabrics with a flexible yarn and a temporary support.

Cold, comprising four polyamide backing yarns, 140 denier, a flexible yarn and a connecting yarn with a diameter of 0.18 mm, is always pulled from the same opening in the loop railing. Under such conditions, the wetting of the stem will be as follows. ^ 3,59332 ij.iisivursi n: υ il elastic yarn 10 j-j, fl chassis yarn 11

With regard to the braided paper weaving pattern, it should be noted that the arrangement of the substrate yarns, the elastic yarns and the flat yarns with respect to each other is arranged in the name so as to create a strip with the best possible flexibility, i. in this case, a compromise is made between sufficient flexibility on the one hand and the avoidance that the loops made of monofilament yarn remain in the correct shape and position on the other hand. This strip will thus have well-opened loops located parallel to the substrate fabric, i. perpendicular or possibly oblique to the longitudinal axis of the strip.

This arrangement makes it possible to carry out the subsequent treatment of the loops, either by heat, mechanically or in some other way, in order to convert them into members which can be gripped by the hooks.

The repetition of the pattern of the passage of the connecting pigs always takes place after six is-kun, in which way its very strong? At the same time, this W-bond gives the fabric a very high flexibility, i.e. the possibility that it will lose its original shape and size and then regain it immediately and completely.

in the fish example has elasticity been achieved after weaving pares? sleep.

Fig. 6 is a warp parallel cutting strip not shown, in which or. inon fiber polyamide yarns 42, elastic yarns 43, monofilament polyamide splicing yarns 44 and inon fiber polyamide weft yarns 45.

In this figure 6, reference numerals 46 show the openings of the loops which form the members to which the hooks engage.

(b) Warps to which the hooks adhere (Figures 9, 10 and 11) The double-base warp comprises a first warp with 160 multifilament polyumane yarns of 140 denier "00 CT / Z to 400 T / S and a second warp, The object comprises 34 sins, 2030 m / k ^ .The connecting element comprises 34 luiaNUc .. with a strength of 90 denier, 200 T / Z.

With regard to the tissue weaving dot paper model, it is observed that the placement of the substrate yarns, the elastic yarns and the connecting yarns is performed precisely in such a way as to provide a strip with the best possible flexibility, as described in connection with the hook connection member.

Its purpose is to form a uniform and corrugated surface with a very high adhesion to the hook connection member, i.e. the suspension member. The repetition of the pattern of the connecting wires is four and five strokes between the loops formed by the same wire so that an M-bond is always formed between the connecting wire and the substrate.

Because the splicing yarns are very well bonded to the fabric and also relate to the weft yarns of the substrate, the placement of the splicing yarns does not affect the flexibility and ease with which the strip can be stretched and then fully restored.

The warp-parallel section of the strip (Fig. 9) clearly shows the structure of the fabric and the course of the warp yarns, as well as the detailed structure of the unstretched strip.

As in the drawings relating to the hook connecting member, i.e. the reference member, reference numerals 42 to ^ 5 denote base yarns, flexible yarns, connecting yarns and weft yarns, respectively.

It should be noted that the relationship between the tensile stresses on the flexible warp yarns, both when the warps are tightened and when weaving, respectively, is of great importance both in terms of the hook connection member and the member connected by the hook connection.

In one particular example, the conditions affecting these ratios are as follows: The principle is first that the flexible yarn, namely the synthetic rubber yarn, is tensioned on the roll i3 59332 so that the privately acting tension is symbolically represented by the number 1. At the same time, it is required that the elastic yarn be wound without elongation, i.e. in such a way that the elongation of the wound elastic yarn is insignificant, i. nonexistent.

Namely, the creation of a flexible warp saöEfctetfcani by tightening in a ratio of 2.8: 1, i.e. so that the elongation coefficient 2.3 is formed on the roll. The flexible warp created using such an elongation is then processed in a weaving machine so that the actual tightening suncie is 1.15: 1, which corresponds to a warp length of 1.15 m per warp wound off the spool.

Of course, it is possible to change this tension, i.e. the elongation ratio, if necessary, taking into account that, on the other hand, the elasticity of the fabric thus formed is also substantially affected by the difference. selected number.

It is clear that woven products made for specific conditions and purposes can then be subjected to finishing and finishing which are known per se in the textile industry.

The purpose of the detailed examples is to explain in more detail the characteristics of the hook-and-loop member in the light of the studies carried out and the results obtained therefrom.

Instead of a hook strip, on the other hand, it is possible to use as a base a rubber or synthetic material made by compression and having a plurality of protrusions, for example sponge-like in nature, which can be connected like hooks to the loops of the astrakhan strip described in FIG.

On the other hand, the loop strip can be made of a substrate of rubber or synthetic material identical to that in which the protrusions are formed, the loops being either embedded or glued to them. In the case that the loops and hooks or sponge-shaped projections are made of metal, it is possible to make the strips by pressing or hitting, i. metal \\ ′ ′ 14,59332 hooks and loops are attached to the substrate, e.g., by a magnetic method. It is also possible to use the tuftifcg method, which is similar to that used in the manufacture of carpets, in which the loops and hooks are knitted on a woven elastic substrate in a net of rubber or synthetic material.

Connecting members made using a rubber or synthetic material as a base and metal hook members can, of course, be subjected to much higher stresses than connecting devices made by weaving. The former are intended, for example, for tying conveyor belts or attaching load covers to vehicles. The parts of the hook connection device, i.e. the suspension device, can then be fastened to the parts to be connected to each other either by riveting or screws or in another suitable way.

The embodiments described above are presented only as some possible embodiments. It is clear that the so-called. males and / or so-called female hook-and-loop supports can be made in a number of different ways, provided that the base made of a suitable material has sufficient flexibility and that at least one of its surfaces has hook-and-loop members and / or members to which the hooks adhere, that two such such substrates can be made not only by weaving but also by Gb JVIl "* 1 Sΐdn.cL 11a, rolling, extraction, spraying, projecting, the superimposed and pressed against each other become firmly connected to each other. , sewing, knitting, anesthesia and the like It is also possible to use any suitable natural or synthetic material.

in all these cases, the direction or directions in which the elastic deformation or elongation takes place are the behavior of the interlocking substrates as schematically shown in Figures 4 and 5, the former denoting the initial position and 59332 the second position under tension. In practice, the distance P, which is the distance between two adjacent hook connection members, i.e. the suspension member (Fig. I +), becomes a distance greater than P after the elastic deformation has taken place. It is clear that when the tensile stress ceases, the latter distance again automatically returns to P. It follows that the relative positions of the hook members and the hook-connected members on the two bases associated with the flexible hook-and-loop member in question, i.e. the suspension member and the closure member, remain substantially constant. acceptable deformation limits in such cases, i.e. the hook joint strength of the hook members is not reduced adversely or not at all.

Also within the scope of the present invention are all applications of such hook coupling devices, i.e. closing devices, i.e. closing devices.
