Abstract

In the case of a carpet comprising a carpet material (1) which has a pile layer (2) in the form of a cut pile and has a backing layer (3), and comprising an anti-slip layer (5) which is retained by means of an adhesive bond (6), the bottom side (4) of which anti-slip layer forms the bottom side of the carpet, edge strips (11) of the carpet material (1) are folded over and adhesively bonded, the side edges (10) of the carpet (1) being formed by the bends between the folded-over edge strips (11) and the rest of the carpet material (1). The pile layer (2) of the folded-over edge strips (11) is sheared off. The anti-slip layer (5) extends only over the region surrounded by the folded-over edge strips (11). A radiation protection layer (7) is arranged between the anti-slip layer (5) and the backing layer (3) of the carpet material (1).

Description

carpet

The invention relates to a carpet with a carpet material which has a pile layer, which is designed as a cut pile, and a back layer, and with an anti-slip layer held by a bond, the underside of which forms the underside of the carpet, with edge strips of the carpet material

folded and glued and the side edges of the carpet from the

Kinks are formed between the folded edge strips and the remaining part of the carpet material and the anti-slip streaks only extend over the area surrounded by the folded edge strips.

It is known to be anti-slip, which can cause the carpet to slip

counteract, attach to the underside of a carpet. There are

Anti-slip known, which are formed from a fleece, which has at least on its underside a non-slip material, for example in the form of a coating or in the form of knobs. If such anti-slip strikes reach the side edge of the carpet, they can be visible from the side, which leads to an unsightly appearance. If, on the other hand, the anti-slip layer ends at a distance from the side edges of the carpet, a kink may be visible on the top of the carpet in the region of the side edge of the anti-slip layer, particularly in the case of relatively thin carpets.

A carpet of the type mentioned at the outset emerges from GB 385,674 A. The carpet has a pile and the edges of the carpet are turned down and glued. In the area between the folded edge strips, an anti-slip layer is glued to the underside of the carpet material, which connects directly to the folded edge strips.

The carpet resulting from DE 20 2004 020 995 U1 has folded-over and glued-on edge strips on the underside which have been sheared off. A radiation protection film emerges from CN 103802384 A, which is a

Base layer, which is formed by a fabric, has a layer of silver fibers and a protective layer of PET.

The object of the invention is to provide an advantageous carpet of the type mentioned. This is achieved according to the invention by a carpet with the features of claim 1.

In the carpet according to the invention, edge strips of the carpet material are folded over and glued, the side edges of the carpet thus being formed by the folds between the folded edge strips and the remaining part of the carpet material. The pile of the folded edge strips has been sheared off. The anti-slip strikes only extend over that of the

folded area surrounding area, i.e. the anti-slip impact does not extend above or below the folded edge strips. Here, the folded edge strips preferably connect directly to the side edges of the anti-slip strikes.

The folded-over edge strips can thus provide a height compensation over the areas adjoining the side edges of the carpet, over which the anti-slip layer does not extend. The formation of a visible kink on the top of the carpet in the area of the side edges of the

Anti-slip strikes can thus be counteracted. Preferably, the sheared surfaces of the folded-up surface facing the substrate lie

Edge strips in one plane with the underside of the anti-slip flaps.

A radiation protection layer is arranged between the anti-slip layer and the back layer of the carpet material. Radiation protection fabrics and films are known and have a conductive material, in particular metal, in order to prevent unwanted electromagnetic radiation. The radiation protection layer is protected against damage by the inventive design. Overall, it becomes a Non-slip carpet with an attractive appearance, stable training and additional functionality of radiation protection provided.

Further advantages and details of the invention are explained below with reference to the accompanying drawings. In this show:

Embodiment of a carpet according to the invention;

4 and 5 sections analogous to FIG. 3 in different manufacturing phases of

Carpet.

An embodiment of a carpet according to the invention and its

Production is explained below with reference to FIGS. 1 -5. The carpet has a carpet material 1 which has a pile layer 2 and a back layer 3 in a conventional manner. The pile layer 2 can also be held in a conventional manner by a fabric layer and can be fixed thereon with a fixing material, for example a latex material. This is not shown in the figures for the sake of simplicity. The back layer 3 can be formed, for example, from a latex material.

The pile layer 2 is formed from a cut pile, so it is velor.

The carpet material 1 can thus be produced in a conventional manner using a tufting process.

An anti-slip layer 5 is arranged below the carpet material 1, the underside 4 of which forms the underside of the carpet. The anti-slip 5 is held by an adhesive 6. In the exemplary embodiment shown, the anti-slip layer 5 is glued to a radiation protection layer 7, which in turn is glued to the back layer 3 of the carpet material 1 by an adhesive 8. The side edges 9 of the anti-slip layers are spaced from the side edges 10 of the carpet. These distances are handled by and

glued edge strips 1 1 of the carpet material 1 bridges. There is thus an adhesive 12 of the back layer 3 of the respective folded edge strip 11 with the back layer 3 of the remaining part of the carpet material 1. The “remaining part of the carpet material 1” is thus the part of the carpet material 1 that forms the upper side of the carpet and extends between the side edges 10 of the carpet. A respective side edge 10 of the carpet is thus separated from the kink between this remaining part of the carpet material 1 and the respective folded edge strips 1 1 formed.

The pile layers 2 of the folded edge strips are sheared off. Here, the sheared surfaces 13 of the surface facing the

folded edge strips 1 1 in a common plane with the underside 4 of the anti-slip film 5, cf. Fig. 3.

In the exemplary embodiment, the lateral edges of the radiation protection layer 7 are congruent with the lateral edges of the anti-slip layer 5

Radiation protection layer 7 a very small thickness, generally of less than 0.1 mm, the radiation protection layer 7 could also be guided into the area of the edge strips 11. In such a variant, the radiation protection layer 7 thus extends into the spaces between the back layers 3 of the edge strips 11 and the back layer 3 of the remaining part of the carpet material 1. The

Radiation protection layer 7 could extend to the crease between the edge strips 11 and the remaining part of the carpet material 1 or end at a distance from it. The back layers 3 of the folded edge strips 11 are thus in this embodiment variant at least over part of their extent with the

Radiation protection layer 7 glued, which in turn is glued to the back layer 3 of the part of the carpet material 1 forming the top of the carpet.

The anti-slip layer 5 can be, for example, a fleece, a fabric, a grid or a Have film, which is provided at least on the underside with a material that has a high coefficient of friction to conventional substrates such as wood, a plastic covering, ceramic or concrete. For example, a continuous coating with a non-slip material can be provided for this purpose or this non-slip material can be provided in places, for example in the form of knobs. The non-slip material can, for example, be or have acrylate.

The thickness of the anti-slip strikes can be, for example, in the range of 4 mm +/- 1 mm.

The anti-slip impact can also improve the acoustic properties of the room. Walking comfort can also be increased.

The radiation protection layer 7 has metal to keep out electromagnetic radiation, for example in the form of metal fibers. It can be in the

Radiation protection layer 7 is a fabric, for example a silver fabric. Instead of a metal, another conductive material can also be present, for example a conductive plastic material. Training as a film is also conceivable and possible.

The adhesive bond 12 between the side edge strips 11 and the remaining part of the carpet material 1 can be formed, for example, by a synthetic rubber adhesive.

The adhesive bond 8 between the radiation protection layer 7 and the back layer 3 of the carpet material 1 can be formed, for example, by a spray adhesive.

The adhesive bond 6 between the anti-slip layer 5 and the radiation protection layer 7 can, for example, be made on the anti-slip layer 5 by the manufacturer

attached adhesive layer.

In the exemplary embodiment shown, the carpet is first manufactured to produce the carpet Radiation protection layer 7 glued to the back layer 3 of the carpet material 1. In addition, the anti-slip layer 5 is glued onto the radiation protection layer 7. This state is shown in Fig. 4.

As a result, the supine position 3 is uncovered by the anti-slip strikes 5

Area coated with the adhesive forming the bond 12. The

Edge strips 11 are turned over and glued to their supine positions, cf. Fig.

5.

In order to form the joints between the folded edge strips 11 in the corner areas, which can for example run diagonally, cf. Fig. 2, the unnecessary sections of the edge strips to be turned over 1 1 before

Cover cut accordingly.

Starting from the state shown in FIG. 5, the pile layer 2 of the folded-over edge strips 11 is sheared off with a shearing tool. Such shear tools are known, for example, for shearing sheep.

The carpet material 1 advantageously has vegetable components, in particular in the area of the pile layer 2, for example corn starch. The proportion of plant components can be more than 30%. Furthermore, the carpet material 1 can have polyamide, in particular in the area of the pile layer 2.

The radiation protection layer 7 in combination with the carpet material 1 can cause a slight static charge, which leads to the trapping of the finest house dust in the carpet. This allows the breathing air to be kept free of stress. The fine dust can be extracted using a suitable vacuum cleaner.

The shielding of electromagnetic radiation by the radiation protection layer 7 can mainly be done by reflection. Since the side edges 10 of the carpet are formed by the folds to form the folded edge strips 11, the carpet in the edge area has the same structure as in the area of the surface. The edge area of the carpet therefore does not need to be specially chained or edged.
