Definitions
- the present invention relates to a floor covering and a method for forming a floor covering according to the independent patent claims.
- Floor covers for example in the form of disposable carpets, are widely used in the trade fair and event sector.
- the task of such disposable carpets is to temporarily create a carpet surface that can be removed from the sub-floor again after the end of the respective event. This enables the properties of the floor covering to be individually adapted depending on the given requirements.
- the adhesive material is that it must be strong enough to withstand loads, usually for several days or even weeks, and still not let the floor cover slip.
- residue-free removal of the adhesive material is often no longer possible.
- the type of attachment described above cannot ensure that the adhesion between the carpet material and the adhesive material is higher than the adhesion between the adhesive material and the substrate.
- adhesive residues often remain on the sub-floor and have to be removed separately from the sub-floor. This requires an additional, undesired work step, as a result of which the laying costs, or in this case the costs for removing the carpet, are additionally increased.
- a reduction in the adhesion of the adhesive material to the substrate would enable the floor covering to be detached more easily, but this would increase the risk of the floor covering slipping and is therefore an undesirable alternative.
- the aim of the invention is to resolve the above-described conflict of objectives between good grip and ease of removal of the ground cover.
- the floor covering according to the invention should therefore be removable from the substrate essentially without leaving any residue and at the same time enable secure adhesion to the substrate.
- a floor covering and a method for forming a floor covering according to the independent patent claims allow, in a synergistic manner, a reduction in the amount of work involved in laying and a reduction in the amount of cleaning required after the floor covering has been removed.
- the invention preferably relates to a floor covering, in particular a disposable carpet, comprising a textile layer, the textile layer comprising a textile material made from a textile fiber composite, an adhesive layer, the adhesive layer comprises an adhesive material, and a cover layer, wherein the cover layer comprises a preferably tear-resistant cover film.
- the textile layer, the adhesive layer and the cover layer are preferably arranged essentially parallel to one another, and the adhesive layer is preferably arranged between the textile layer and the cover layer.
- the adhesive layer is designed such that the bottom cover is self-adhesive and can be removed again without leaving any residue, and that the adhesive material has at least partially penetrated the textile fiber composite so that the adhesive layer is anchored in the textile layer.
- the adhesive material is at least partially arranged in the fiber interstices of the textile fiber composite.
- connection between textile layer and adhesive layer is established at a temperature of the textile material in the connection area between textile layer and adhesive layer of more than 40 ° C, preferably between 50 ° C and 60 ° C.
- the adhesive material comprises or consists of a pressure-sensitive hot-melt adhesive.
- the viscosity of the adhesive material is greater than 20,000 mPa * s, preferably between 30,000 mPa * s and 40,000 mPa * s.
- the adhesive material is essentially free of organic solvents. “Essentially free from” means in particular that the content is below 1% by weight, typically below 0.5% by weight, preferably below 0.1% by weight.
- the softening point of the adhesive material is above 70.degree. C., preferably above 90.degree. If necessary, it is provided that the elastic expansion of the cover film is greater than 2%, preferably between 3% and 5%.
- the textile material is a woven material or a nonwoven material, which preferably comprises or consists of polyamide fibers and / or polypropylene fibers.
- the textile material is a needle punched textile material.
- the adhesion of the adhesive layer to the substrate after a static load test is less than 50% above the initial adhesion of the adhesive layer on the substrate, the load test being carried out by loading the adhesive layer of the floor covering with a force of 70 to 100 N / cm 2 over a period of one day.
- the textile layer has a thickness between 500 ⁇ m and 5000 ⁇ m, preferably between 1000 ⁇ m and 3000 ⁇ m.
- the adhesive layer has a thickness between 20 ⁇ m and 100 ⁇ m, preferably between 50 ⁇ m and 70 ⁇ m, and / or
- the cover layer has a thickness between 10 ⁇ m and 50 ⁇ m, preferably between 20 ⁇ m and 40 ⁇ m.
- the base cover is a roll material with a length of at least 5 m.
- the adhesive layer is arranged in the form of a strip on the textile layer, in particular along the longitudinal extension direction of a roll material.
- the adhesive layer may not completely cover the textile layer.
- the invention preferably further relates to a method for forming a floor covering, in particular a floor covering according to the invention, comprising the following steps:
- the floor covering comprising the following layers: a textile layer comprising the textile material; an adhesive layer comprising the adhesive material; and a cover layer comprising the cover sheet; wherein the textile layer, the adhesive layer and the cover layer are arranged essentially parallel to one another, and wherein the adhesive layer is arranged between the textile layer and the cover layer.
- the adhesive material at least partially penetrates the textile fiber composite and / or is mixed with it, so that the adhesive layer is anchored in the textile layer.
- the temperature of the textile material in the connection area between textile layer and adhesive layer in step (b) is greater than 40 ° C., preferably between 50 ° C. and 60 ° C.
- step (b) comprises the following sub-steps:
- step (b) comprises the following step:
- step (c) comprises one or both of the following sub-steps: (c ') calendering the base cover with a calendering device, and / or (c “) pressing the base cover with a belt press.
- the adhesive layer is heated to a temperature of greater than 60 ° C. before it is connected to the textile layer.
- the floor covering according to the invention preferably comprises a textile layer, an adhesive layer and a cover layer, which are arranged essentially parallel to one another.
- the adhesive layer is preferably arranged between the covering layer and the textile layer.
- the adhesive layer is optionally arranged in the form of a strip on the underside of the textile layer.
- the adhesive layer can extend in the form of a strip along the longitudinal extension direction of the floor covering.
- two, three, four or more strips of the adhesive layer running essentially parallel to one another can be arranged on the textile layer.
- the adhesive layer runs in particular over the entire length of the floor covering.
- the length of the roll goods can in particular be between 25 m and 50 m, preferably about 50 m.
- the covering layer is only arranged in those areas of the floor covering where the adhesive layer is located.
- the textile layer can therefore be free of other layers in certain areas, in particular free of an adhesive layer or a cover layer.
- the adhesive material of the adhesive layer is at least partially mixed with fibers of the textile material of the textile layer or penetrated into the fiber composite.
- an anchoring of the textile layer to the adhesive layer can thereby be achieved. This enables, among other things A residue-free detachment of the floor cover from a substrate by firmly connecting the two layers.
- connection area can be provided in which the adhesive material is pressed between the textile fibers.
- the adhesive material can be present in the interstices between the fibers of the textile fibers.
- the connection area can be at least 10 miti, optionally at least 20 miti, thick, the connection area usually not having any sharply defined boundary surfaces.
- Textile fibers of the textile layer can optionally be partially embedded in the adhesive layer in order to achieve good anchoring. If necessary, the textile fibers can be partially enclosed by the adhesive material.
- the anchoring can be achieved by pressing the textile layer and the adhesive layer at an elevated temperature, in particular at a temperature of more than 60.degree.
- the stable connection between the textile layer and the adhesive layer can ensure that the adhesion between the textile layer and the adhesive layer is greater than the adhesion between the adhesive layer and the substrate.
- “Residue-free” in the context of the present invention means in particular that when removing, in particular peeling off, the floor covering from the substrate, no adhesive material remains on the substrate which would then have to be removed chemically or mechanically.
- the floor covering can be removed from the substrate in a peeling step without any further mechanical or chemical aids.
- Subsurface can denote any surface that is suitable for attaching a floor covering according to the invention.
- the subsurface is a floor or a floor covering such as a concrete, asphalt, plastic or wooden floor essentially flat surface structure.
- the subsurface is a smooth, solid floor in an event hall.
- the ground can also have steps.
- the adhesive layer can be designed in such a way that it remains fully adhered to the textile layer when the floor covering is removed from the substrate. The removal can take place in particular by pulling the carpet off the substrate.
- the adhesive material of the adhesive layer can optionally be a rubber material, in particular a synthetic rubber material.
- the adhesive material can have one or more of the following characteristics:

- the load test can be carried out by applying a static force of 70 to 100 N / cm 2 , in particular 80 N / cm 2 , to the floor covering over a period of one day.
- the area refers in particular to the area of adhesive material that is connected to the substrate. Wood, concrete, asphalt, plastic and the like can be used as substrates for the load test.
- the cover layer can be detached from the adhesive layer so that it can be brought into contact with the substrate.
- a floor covering according to the invention is laid in particular as follows: removing a first section of the covering layer and gluing the floor covering to the substrate in the area of the first section. Then lightly pretension the base cover. Thereupon, removing a second section of the cover layer from the adhesive layer and gluing the floor covering to the substrate in the area of the second section.

- the adhesive-film composite produced in this way can be connected to the textile material so that the floor covering is formed.
- a pressing step is provided in order to compact the layers and in particular to improve the anchoring between the textile layer and the adhesive layer.
- the pressing step can include, for example, calendering and / or belt pressing of the base cover.
- the textile material can be at least partially preheated.
- the adhesive layer can be heated.
- a method according to the invention can be integrated into the method of setting up a floor covering.
- a fastening method can include: fastening a textile material, connecting the layers according to the method according to the invention, assembling the Bottom cover.

- FIG. and FIG. 2 shows a schematic view of a production plant for carrying out a method according to the invention in accordance with an exemplary embodiment of the invention.
- the figures show the elements bottom cover 1, textile layer 2, adhesive layer 3, cover layer 4, surface 5, back 6, cover film roll 7, deflection roller 8, tension adjustment device 9, coating station 10, adhesive-film composite 11, heating device 12, conveyor roller 13, calendering device 14, belt press 15 are shown.
- FIG. 1a shows a schematic sectional view of a floor cover 1 according to the invention according to a first exemplary embodiment.
- An enlarged section of FIG. 1 a is shown in FIG. 1 b.
- the two figures are described together below. For better visibility of the individual parts, the figures are not shown to scale.
- the bottom cover 1 is a roll material with a length of about 50 m, which is shown in Fig. 1a and 1b in cross section along its width.
- the floor covering 1 comprises a textile layer 2, an adhesive layer 3 and a cover layer 4.
- the adhesive layer 3 is arranged in two strips along the longitudinal extension direction of the floor covering 1.
- the cover layer 4 is only provided in those areas of the base cover 1 where the adhesive layer 3 is located.
- the textile layer 2 comprises a surface 5 and a back 6.
- the back 6 has a slight structure.
- the adhesive layer 3 is connected to the back 6 of the textile layer 2. Due to the structuring of the back, the adhesive layer 3 is also slightly structured and not completely flat.
- the adhesive layer 3 is formed continuously and without interruptions. In the connection area between textile layer 2 and adhesive layer 3, the adhesive material has partially penetrated into the fiber composite of the textile material and thereby mixed with the fibers in sections. This enables particularly strong adhesion between the textile layer 2 and the adhesive layer 3.
- the textile material of the textile layer 2 is a needle punch material with polypropylene fibers.
- the fleece material is strengthened by impregnation with synthetic latex.
- the thickness of the textile layer 2 is about 2 mm in this example.
- the adhesive layer 3 in this example is preferably a high viscosity hot-melt adhesive made of synthetic rubber material having a viscosity of about 30,000 mPa * s.
- the adhesive material has a low content of plasticizers, and is substantially free of organic solvents.
- the adhesive material has a high bond strength even when cold. This allows the floor cover to keep its position while laying.
- the adhesion of the adhesive material to the surface during use only increases by around 40%. This enables residue-free removal from the surface even after prolonged use. Determination of liability after use can in particular be determined with a load test, as explained in detail in the general description.
- the softening point of the adhesive material is above 90 ° C.
- the properties of the bond are not strongly influenced by external influences such as temperature changes.
- the adhesive material enables good initial adhesion to the substrate at temperatures between 5 and 10 ° C.
- the thickness of the adhesive layer 3 is about 60 gm in this example.
- the cover layer 4 is well connected to the adhesive layer 3 and as a result does not come off by itself.
- the cover film, which is used as cover layer 4 has an elastic elongation between 3% and 5%. As a result, when the floor covering 1 is laid, a slight elongation is possible without the covering layer 4 becoming detached or tearing.
- the cover layer 4 is formed from a film made of oriented polypropylene which has a thickness of approximately 30 ⁇ m.
- the floor cover 1 according to the invention can lead to a time saving of 30% to 50% compared to a conventional laying process for floor coverings described at the outset.
- FIG. 2 shows a schematic view of a lowering position system for carrying out a method according to the invention in accordance with an exemplary embodiment of the invention.
- the system shown is integrated into an entire installation process for a floor covering.
- the textile layer 2 is provided upstream by a textile layer manufacturing system (not shown) and the floor covering 1 produced is further processed downstream in a floor covering assembly system (not shown).
- the method according to the invention includes the provision of textile material, adhesive material and cover film, as well as the joining of said materials to form a floor covering with a textile layer 2, an adhesive layer 3 and a cover layer 4.
- the cover layer 4 is provided by a cover film roll 7 and is continuously unwound. After the film has been guided over deflection rollers 8 and the tension has been adjusted using a tension adjustment device 9, the cover film is coated with adhesive material in a coating station 10 in order to form an adhesive-film composite 11.
- the adhesive-film composite 11 is heated to a temperature of about 60 ° C. by means of a fusing device 12 on the side of the adhesive material and then brought together with the textile layer 2.
- the textile material of the textile layer 2 is continuously conveyed via conveyor rollers 13.
- the surface of the textile material which is to be brought into contact with the adhesive layer, is heated to a temperature of about 60 ° C. by means of a further heating device 12.
- the two fursing devices 12 are infrared fleizers.
- the connection between the individual layers is made by pressing.
- the pressing takes place in two successive steps, first by calendering in a calendering device 14 and then by pressing in a belt press 15.
- the floor covering 1 produced in this process has a strong fluff between the textile layer 2 and the adhesive layer 3.
- this strong fluffing is made possible by the increased temperature around the area of the connecting layer between textile layer 2 and adhesive layer 3.
- the adhesive layer 3 can partially penetrate into the textile layer 2 and anchor the two layers to one another.
