Avantageusement, l'étape b) est réalisée à une température comprise entre 100° et 220° C, et notamment entre 205 et 215°C.Advantageously, step b) is carried out at a temperature between 100 ° and 220 ° C, and in particular between 205 and 215 ° C.

L'invention a également trait à un appareillage pour la mise en oeuvre de ce procédé pour fabriquer ce matériau de revêtement mural. Cet appareillage comprend un rouleau chauffant d'axe sensiblement horizontal; une bande transporteuse formée d'un tapis sans fin qui entoure partiellement ce rouleau chauffant et qui est appliquée contre celui-ci; des dispositifs situés en amont du rouleau chauffant pour dérouler les éléments constituant le revêtement et éventuellement le matériau comportant des motifs décoratifs; ainsi qu'en aval par rapport au rouleau chauffant, un rouleau enrouleur du matériau de revêtement mural et éventuellement un rouleau enrouleur pour le matériau ayant comporté des motifs décoratifs;et des dispositifs régulant la tension des différents éléments ainsi que de la bande transporteuse.The invention also relates to an apparatus for implementing this method for manufacturing this wall covering material.

La description qui va suivre et qui ne présente aucun caractère limitatif, doit être lue en regard des figures annexées parmi lesquelles :

  • - la figure 1 représente une coupe transversale du matériau de revêtement mural selon la présente invention ;
  • - la figure 2 est une vue de dessus de ce matériau ; et
  • - la figure 3 est une représentation schématique de l'appareillage pour fabriquer ce matériau de revêtement mural.
The description which follows and which is in no way limiting, should be read with reference to the appended figures, among which:
  • - Figure 1 shows a cross section of the wall covering material according to the present invention;
  • - Figure 2 is a top view of this material; and
  • - Figure 3 is a schematic representation of the apparatus for manufacturing this wall covering material.

Ainsi qu'on peut le voir sur les figures 1 et 2, un matériau de revêtement mural selon la présente invention, référencé 1 dans son ensemble, est constitué par les trois éléments suivants : une nappe inférieure 2 en une mousse plastique, une nappe intermédiaire 3 constituée par un film thermocollant et une nappe supérieure 4 textile.As can be seen in Figures 1 and 2, a wall covering material according to the present invention, referenced 1 as a whole, consists of the following three elements: a lower ply 2 made of plastic foam, an intermediate ply 3 constituted by a fusible film and a textile upper sheet 4.

La nappe inférieure 2 peut être une mousse plastique de type polyester ou latex. Selon un mode de réalisation préférée de l'invention, elle est en une mousse polyéther qui présente des nossibilités de traitement notamment pour la rendre imputrescible et/ou auto-extinguible, c'est-à-dire que cette mousse ne conduit pas la flamme.The lower layer 2 can be a plastic foam of polyester or latex type. According to a preferred embodiment of the invention, it is made of a polyether foam which has treatment possibilities in particular to make it rot-proof and / or self-extinguishing, that is to say that this foam does not conduct the flame .

L'épaisseur de cette nappe inférieure 2 peut être comprise entre 1 et 10 millimères ; elle est.de préférence de trois millimètres environ. Mais il est bien évident que, en fonction des besoins d'isolation spécifique, cette épaisseur peut être augmentée ou diminuée.The thickness of this lower ply 2 can be between 1 and 10 millimeters; She is from preferably about three millimeters. However, it is obvious that, depending on the specific insulation requirements, this thickness can be increased or decreased.

La nappe intermédiaire 3 est par exemple un film polyéthylène extrudé et soufflé qui a subi un traitement spécifique pour avoir un pouvoir thermocollant entre 100 et 220°C. Selon le cas, la structure de ce film est conçue pour se craqueler lors du thermocollage afin de conserver la possibilité d'échanges d'air entre la paroi et le mur interne de la pièce, ou bien pour ne pas se craqueler afin de former une barrière complètement imperméable à l'air. Ce film joue également un rôle de barrière contre les ultra-violets : il protège ainsi la mousse constituant la nappe inférieure 2 contre l'-oxydation sous l'effet de ce rayonnement et empêche celle-ci de prendre une coloration jaune.The intermediate sheet 3 is for example an extruded and blown polyethylene film which has undergone a specific treatment to have a fusible power between 100 and 220 ° C. Depending on the case, the structure of this film is designed to crack during heat sealing in order to preserve the possibility of air exchanges between the wall and the internal wall of the room, or else not to crack in order to form a barrier completely airtight. This film also plays a role of barrier against ultraviolet rays: it thus protects the foam constituting the lower sheet 2 against oxidation under the effect of this radiation and prevents it from taking a yellow coloring.

Quant à la nappe supérieure 4 textile, elle peut consister en des fibres polyester, discontinues ou continues, entremêlées sans liant, de manière à constituer une structure ressemblant à un textile tissé traditionnel. Elle est micro-perforée ou non pour donner l'aspect d'un tissage classique. Selon un mode de réalisation de l'invention, cette nappe supérieure 4 peut comporter elle-même des motifs décoratifs comme représenté sur la figure 2.As for the upper textile ply 4, it may consist of polyester fibers, discontinuous or continuous, intermingled without binder, so as to constitute a structure resembling a traditional woven textile. It is micro-perforated or not to give the appearance of a conventional weaving. According to one embodiment of the invention, this upper ply 4 may itself include decorative patterns as shown in FIG. 2.

, Chaque nappe adhère à la nappe immédiatement voisine., Each tablecloth adheres to the immediately neighboring tablecloth.

Un tel matériau de revêtement mural présente des caractéristiques d'absorption acoustique, d'isolation phonique et thermique fort intéressantes. Notamment il a été déterminé que l'absorption acoustique est de l'ordre de 0,3 et que la diminution du bruit est de 6 à 8 décibels. Quant à l'isolation thermique, elle est concrétisée par une élévation de température dans la pièce de 1 à 3°C, selon la qualité de l'isolation déjà existante du mur et de l'importance en surface des parties de la pièce exposées directement au froid.Such a wall covering material has very interesting acoustic absorption, sound and thermal insulation characteristics. In particular, it has been determined that the acoustic absorption is of the order of 0.3 and that the reduction in noise is from 6 to 8 decibels. As for the thermal insulation, it is concretized by a rise in temperature in the room from 1 to 3 ° C, according to the quality of the already existing insulation of the wall and the importance on the surface of the parts of the room exposed directly cold.

Par ailleurs, il a été noté que ce matériau permet d'éliminer la condensation sur les murs ou plafonds.Furthermore, it was noted that this material eliminates condensation on walls or ceilings.

Ce matériau de revêtement mural peut se poser en collé-tendu, ce qui augmente son pouvoir isolant en créant une mince couche d'air entre le mur et lui, ou en collage, sans nécessiter la préparation des murs : en effet, il peut être posé directement sur le béton de décoffrage ou sur les agglomérés.This wall covering material can be laid in bonded-stretch, which increases its insulating power by creating a thin layer of air between the wall and it, or in bonding, without requiring the preparation of the walls: in fact, it can be laid directly on formwork concrete or on agglomerates.

Quant au procédé pour fabriquer ce matériau de revêtement mural, il comprend les étapes suivantes

  • a) on superpose,de façon continue, la nappe inférieure 2, la nappe intermédiaire 3 et la nappe supérieure 4 ; puis
  • b) on colle par un apport de chaleur extérieur chaque nappe à la nappe voisine, les nappes étant maintenues pressées les unes contre les autres.
As for the process for manufacturing this wall covering material, it includes the following steps
  • a) the lower ply 2, the intermediate ply 3 and the upper ply 4 are continuously superimposed; then
  • b) each ply is bonded by an external heat supply to the neighboring ply, the plies being kept pressed against each other.

Si la nappe supérieure 4 ne comporte pas de motifs décoratifs, on peut disposer sur elle un matériau qui en comporte. Lors de l'étape b) sous l'effet de la chaleur et de la pression, les motifs décoratifs sont transférés sur la nappe supérieure 4.If the upper ply 4 does not include decorative patterns, a material can be placed thereon. During step b) under the effect of heat and pressure, the decorative patterns are transferred to the upper ply 4.

L'étape b) est réalisée à une température comprise entre 100 et 220° C, et de préférence entre 205 et 215°C, ou de l'ordre de 210°C.Step b) is carried out at a temperature between 100 and 220 ° C, and preferably between 205 and 215 ° C, or of the order of 210 ° C.

L'appareillage pour la mise en oeuvre de ce procédé comprend un rouleau chauffant 5 d'axe horizontal et une bande transporteuse 6 formée d'un tapis sans fin qui entoure partiellement ce rouleau et qui est appliquée contre lui de façon connue en soi. La tension de cette bande est réglée par un dispositif 7. Le rouleau chauffant 5 comporte des résistances chauffantes qui sont noyées dans une huile thermofluide de telle sorte que son enveloppe est portée à la température voulue. Quant au tapis sans fin constituant la bande transporteuse 6, il est par exemple en téflon. Le rouleau chauffant 5 et la bande transporteuse 6 sont montés de façon connue en soi sur un même bâti 8.The apparatus for implementing this method comprises a heating roller 5 with a horizontal axis and a conveyor belt 6 formed of an endless belt which partially surrounds this roller and which is applied against it in a manner known per se. The tension of this strip is adjusted by a device 7. The heating roller 5 includes heating resistors which are embedded in a thermofluidic oil so that its envelope is brought to the desired temperature. As for the endless belt constituting the conveyor belt 6, it is for example made of Teflon. The heating roller 5 and the conveyor belt 6 are mounted in a manner known per se on the same frame 8.

En am.ont du rouleau chauffant 5, sont disposés sur un premier bâti 9, un rouleau 10 de mousse de polyéther 2 (figure 1) et un rouleau. 11 d'un textile synthétique 4. Sur un second bâti 12, est disposé un rouleau 13 pour le matériau comportant des motifs décoratifs : ce matériau est par exemple du papier. Quant au rouleau 14 de film polyéthylène,il peut être monté sur le bâti 8.Upstream of the heating roller 5, are arranged on a first frame 9, a roller 10 of polyether foam 2 (Figure 1) and a roller. 11 of a synthetic textile 4 . On a second frame 12, a roller 13 is arranged for the material comprising decorative patterns: this material is for example paper. As for the roll 14 of polyethylene film, it can be mounted on the frame 8.

Bien évidemment, ces rouleaux 10,11,13 et 14 sont disposés de telle sorte que les éléments se présentent dans l'ordre souhaité au niveau du rouleau chauffant 5.Obviously, these rollers 10, 11, 13 and 14 are arranged so that the elements are presented in the desired order at the level of the heating roller 5.

En aval du rouleau chauffant, on dispose un rouleau 15 autour duquel sera enroulé le matériau de revêtement mural selon la présente invention, et un rouleau 16 pour le papier ayant servi à transférer les motifs décoratifs. Le rouleau 15 est monté sur un troisième bâti 17.Downstream of the heating roller, there is a roller 15 around which the wall covering material according to the present invention will be wound, and a roller 16 for the paper used to transfer the decorative patterns. The roller 15 is mounted on a third frame 17.

A la sortie du rouleau chauffant 5 et sur le bâti 8, est monté un dispositif de délignage 18 tel que des ciseaux électriques, qui découpe les bords du matériau de revêtement mural, de façon qu'il ait une largeur uniforme.At the outlet of the heating roller 5 and on the frame 8, is mounted an edging device 18 such as electric scissors, which cuts the edges of the wallcovering material, so that it has a uniform width.

Cet appareillage comprend également une hotte 19 pour l'évacuation des vapeurs, cette évacuation étant réalisée par aspiration, ainsi qu'un dispositif 20 pour l'évacuation des découpes provenant du dispositif de délignage 18.This apparatus also comprises a hood 19 for the evacuation of the vapors, this evacuation being carried out by suction, as well as a device 20 for the evacuation of the cuts coming from the edging device 18.

Sur chaque trajet des nappes, ainsi que sur celui-du matériau issu du rouleau chauffant 5, sont disposés des dispositifs régulant leur tension.On each path of the sheets, as well as on that of the material from the heating roller 5, devices are arranged regulating their tension.

_Les nappes inférieure 2, intermédiaire 3 et supérieure 4 ainsi qu'éventuellement le papier portant des motifs décoratifs sont introduits entre le rouleau chauffant 5 et la bande transporteuse 6. Par le mouvement de ces deux organes, l'ensemble ci-dessus s'enroule partiellement autour du rouleau chauffant 5 : les nappes se collent entre elles et les motifs décoratifs sont transférés du papier sur la nappe supérieure, sous l'action de la chaleur du rouleau chauffant 5 et de la pression exercée par la bande transporteuse 6. A la sortie, on récupère le papier autour dû rouleau 16 et le matériau de revêtement mural autour du rouleau 17 après être passé dans le dispositif de délignage 18._The lower 2, intermediate 3 and upper 4 layers as well as possibly the paper bearing decorative patterns are introduced between the heating roller 5 and the conveyor belt 6. By the movement of these two members, the above assembly is wound up partially around the heating roll 5: the tablecloths stick together and the decorative patterns are transferred from the paper to the upper tablecloth, under the action of the heat of the heating roll 5 and the pressure exerted by the conveyor belt 6. At the outlet, the paper is recovered around the roller 16 and the wall covering material around the roller 17 after passing through the edging device 18.

On peut noter que cet appareillage permet donc simultanément le complexage de trois éléments différents et l'impression par sublimation.It may be noted that this apparatus therefore simultaneously allows the complexing of three different elements and the sublimation printing.
