Abstract

A layer for fixing a mat, carpet or rug comprises a sheet of fibres (3), a flexible sheet of foam (1) and an intermediate film (2) between the fibre and foam layers wherein the sheet of fibres is needled though the intermediate film and foam to connect the layers together. Preferably, the fibres are made of pre-calendered polyester, the film of polyethylene and the foam is cellular. A layer of permanent adhesive (4, 5) may be applied, sprayed or coated, to the top of the sheet of fibres and to the bottom of the sheet of foam. The intermediate film prevents crushing by forming a mechanical barrier preventing migration of the adhesive. The cellular foam may comprise printed text or images e.g. trade marks or instructions for use.

Description

Layer for fixing products such as mats, carpets or rugs The present
invention relates to a layer for fixing a mat, carpet or rug, which is placed between the floor and the article to be fixed, its fixing surface being formed by a sheet of fibres and a flexible sheet of foam which are connected to one another by the needling of fibres into and through the foam.
According to the document FR 83 10 334, a fixing layer of this type is already in existence.
The fixing layer described in that document was, at that time, a significant improvement as a locking means to prevent the sliding of mats, in comparison with mere plastic grids coated with PVC or natural or artificial latex.
However, the known fixing layer has the drawback of being crushed after a certain period of use, the polyester fibres, in particular, having a tendency to be crushed and to adhere to the boundary face of the sheet of foam. This reduces its versatility if the mat or rug is placed on a hard floor. If it is placed on a textile floor and the cushioning effect is no longer produced under ideal conditions, the mat placed on the fixing layer risks moving locally, becoming wrinkled or being deformed again.
The object of the present invention is to develop a layer for fixing mats, carpets or rugs on a Roadblock, marble or tiled floor, a fitted carpet or any hard or smooth floors which may or may not be provided with a textile covering to prevent crushing of the layer of fibres in order to increase the efficacy of the fixing layer and its service life.
The invention accordingly relates to a fixing layer of the above-defined type characterized by an intermediate film between the sheet of fibres and the sheet of foam, the sheet of fibres being needled through the intermediate film and the sheet of foam.
The intermediate film between the sheet of fibres and the sheet of foam prevents migration of the adhesive from the surface of the fibres and attachment and crushing thereof against the sheet of foam, preserving the efficacy of the fixing layer for a very long time, in particular under very harsh conditions of use on a floor covered with a flexible textile product such as a fitted carpet of which the pile tends to displace the fixing layer in all transverse directions, depending on the pressure or crushing exerted and the direction of movement.
The intermediate film also allows the sheet of foam attached to the floor and the sheet of fibres to be mechanically separated; the fibres therefore act as articulated parallelograms. The fibres are crushed by the effect of the weight exerted by a foot and return without entraining the lower sheet, when the weight is removed. Therefore, the intermediate film forming a barrier mechanically isolates the two sheets which remain different and each fulfil a different function. The sheet in contact with the floor has the function of enabling the layer for fixing the mat to remain in contact with the floor owing to its permanent adhesive. The upper sheet formed by fibres is connected to the lower sheet and is articulated thereto, thus fulfilling the function of absorbing the lateral displacement; the lower sheet remains immobile whereas the upper sheet absorbs the two-and-fro movements caused by the pressures exerted by walking on the mat. If the fixing layer is interposed between a fitted carpet and a mat, the sheet of foam will be on the mat sided in the case of a mat placed on a hard floor such as a slab, the foam will be on the slab side.
According to a further advantageous characteristic, the fibres are made of polyester and the sheet of fibres is preferably pre-calendered after itself being needled and through the sheet of foam. The foam is preferably cellular and the film separating the sheet of fibres from the sheet of foam is a film of polyethylene. Finally, a permanent adhesive is applied to the external surfaces of the complex thus formed by the polyester fibres of the intermediate polyethylene film and the cellular foam traversed by a portion of the fibres of the upper sheet.
The present invention will be described in more detail hereinafter by means of the accompanying drawings, in which: Fig. 1 shows a stage in the production of a fixing layer according to the invention, Fig. 2 shows a second stage of manufacture of the fixing layer according to the invention and the layer obtained.
According to Fig. 1, the invention relates to a layer for fixing a mat, carpet or rug on the floor which itself consists of a textile surface such as a pile or loop-type fitted carpet or a hard surface such as a woodblock floor, a slab of marble or tiling, or quarry tiles.
The fixing layer is composed of a flexible sheet of foam 1 of which one face 1A is covered with an intermediate film 2 which itself receives a sheet of fibres 3. These polyester fibres 3 are preferably pre-calendered before being applied to the surface 2A of the intermediate film 2. The installed assembly is then needled 4 so that certain fibres 31 are passed through the film 2 and are attached in the sheet of foam 1, then certain fibres 32 are passed through the sheet of foam 1.
The needling operation is shown schematically by a needling device 41 carrying needles 42 and performing a vertical two-and-fro movement (double arrow A) to entrain and prick fibres through the film 2 into the sheet of foam 1 and through the sheet of foam 1.
The film 2 is preferably made of polyethylene and the foam 1 a cellular foam.
This first stage is shown schematically in Fig. Fig. 2 shows a fixing layer obtained after needling, schematically illustrating the fibres 31 integrated in and through the sheet of foam 1.
A layer of permanent adhesive 4 is applied to the top of the sheet of fibres 3 and a sheet of permanent adhesive 5 to the face 1B of the sheet of foam 1 by spraying or coating after this needling operation.
The fixing layer is preferably produced continuously by the passage of a sheet of foam 1 on which there are placed an intermediate film 2 and then a pre-calendered sheet of fibres, needling is carried out next and finally the layer of permanent adhesive 4 is applied to the top of the sheet of fibres 3 and to the bottom of the sheet of foam 1.
The sheet produced in this way is rolled so it can be cut on demand or may be already cut up into stacked panels.
The sheet of foam 1 may comprise inscriptions such as a trade mark or instructions for use or a square grid imprinted to assist cutting, on its face 1B. The cellular foam may comprise text or black or coloured printed images.
Finally, it is observed that the profile of the complex formed exhibits two distinct layers separated by the intermediate film which is itself visible.
