Abstract

The press comprises a lower platen, equipped with the tools for thermo-welding the material in accordance with the quilted pattern. The material combines a plastic foam padding bonded to the required surface covering; this is laid onto the lower platen tools, being held by suction. An upper platen descends onto the material, to apply pressure and complete the thermo-welding process. This upper platen is heated and is operated by a dual toggle link mechanism connected to a power cylinder. The thermo-welding tools move a short distance upwards to impress the pattern.

Description

La présente invention concerne un matériau en forme de nappe, telle qu'une nappe matelassée et un procédé de fabrication d'un tel matériau. The present invention relates to a sheet-like material, such as a padded sheet and to a method of manufacturing such a material.

On connatt déjà divers types de matériaux matelassés, en particulier, des matériaux destinés à former des revêtements pour des fauteuils, des housses de fauteuils et de sièges d'automobiles, des tissus d'ameublement, des tentures murales, etc. Various types of quilted materials are already known, in particular, materials intended to form coatings for armchairs, covers for armchairs and car seats, upholstery fabrics, wall hangings, etc.

La présente invention a pour but de créer un procédé de fabrication d'un matériau matelassé et capitonné du type ci-dessus, qui permette une fabrication en grande série, peu coûteuse, sans que cela ne soit au détriment de la qualité du matelassage et du capitonnage ainsi que les produits obtenus pour la mise en oeuvre du procédé. The present invention aims to create a method of manufacturing a padded and padded material of the above type, which allows mass production, inexpensive, without this being at the expense of the quality of quilting and upholstery as well as the products obtained for the implementation of the process.

A cet effet, l'invention concerne un produit en forme de surface matelassée et capitonne formée d'une nappe de revêtement, et d'une nappe de base en un matériau à cellules élastiques susceptiblesd'être comprimées, procédé caractérisé en ce que l'on écrase localement les cellules suivant la trace du dessin du capitonnage et de matelassage à réaliser et On bloque de façon permanente les cellules à l'état écrasé. To this end, the invention relates to a product in the form of a padded and padded surface formed by a covering ply, and a base ply made of a material with elastic cells capable of being compressed, process characterized in that the the cells are locally crushed according to the trace of the padding and quilting design to be produced and the cells are permanently blocked in the crushed state.

La présente invention sera décrite plus en détail à l'aide des dessins annexés, dans lesquels
-- la figure 1 est une coupe très schématique d'un produit selon l'invention formé de deux couches avant la réalisation du capitonnage.
The present invention will be described in more detail with the aid of the accompanying drawings, in which
- Figure 1 is a very schematic section of a product according to the invention formed of two layers before the realization of the upholstery.

- la figure 2 montre la couche de la figure 1 après compression et thermocollage. - Figure 2 shows the layer of Figure 1 after compression and heat sealing.

- la figure 3 est une coupe d'un second mode de réalisation d'un produit selon l'invention. - Figure 3 is a section of a second embodiment of a product according to the invention.

- la figure 4 est une coupe très schématique des diverses couches constituant un autre mode de réalisation, selon l'invention, avant que ces diverses couches ne soient partiellement solidarisées. - Figure 4 is a very schematic section of the various layers constituting another embodiment, according to the invention, before these various layers are partially secured.

- la figure 5 est une vue en coupe très schématique d'un dispositif pour la réalisation d'un revêtement, selon l'invention, par un procédé discontinu, pièce par pièce. - Figure 5 is a very schematic sectional view of a device for producing a coating, according to the invention, by a batch process, piece by piece.

Selon les figures 1, 2, le mode de réalisation le plus simple de l'invention se compose d'une nappe de revêtement 1 et d'une nappe de base à cellules 3 (figure 1). On comprime et on colle les deux nappes 1, 3 comme indiqué à la figure 2 pour donner à la surface un effet de matelassage et de capitonnage laissant une trace T suivant le dessin choisi c'est-à-dire, une ligne, un point, une petite surface etc. According to Figures 1, 2, the simplest embodiment of the invention consists of a covering ply 1 and a basic cell ply 3 (Figure 1). We compress and glue the two layers 1, 3 as shown in Figure 2 to give the surface a quilting and quilting effect leaving a trace T according to the chosen design, that is to say, a line, a point , a small area etc.

Pour cela lors du collage de la nappe 1 sur la nappe 3 suivant la trace T (les autres surfaces des nappes 1, 3 étant nécessairement laissées libres sans être collées pour donner le gonflant) on cqmprime suivant la trace T pour écraser de façon permanente au moins une partie des cellules ou alvéoles de la nappe 3. Comme cette compression se fait simultanément au collage (toujours suivant la trace T) il se produit également un collage au moins partiel des cellules écrasées (zone C), ce qui fixe les cellules à l'état écrasé et participe à l'effet de gonflant du matelassage et du capitonnage. For this during the bonding of the sheet 1 on the sheet 3 along the trace T (the other surfaces of the sheets 1, 3 being necessarily left free without being glued to give the bulking), it is printed according to the trace T to crush permanently at at least part of the cells or cells of the ply 3. As this compression takes place simultaneously with bonding (always following trace T) there is also produced at least partial bonding of the crushed cells (zone C), which fixes the cells to the crushed state and contributes to the bulking effect of the quilting and padding.

Suivant le résultat à obtenir, cet écrasement permanent peut être plus ou moins formé c'est-à-dire représenter une partie plus ou moins importante de l'épaisseur de la nappe 3, voire la totalité de la nappe 3 au droit de la trace T. Depending on the result to be obtained, this permanent crushing can be more or less formed, that is to say represent a more or less significant part of the thickness of the ply 3, or even the whole of the ply 3 in line with the trace. T.

Selon la figure 3, le produit est réalisé à partir d'un ensemble formé d'une nappe de revêtement et d'une nappe de base 3 en deux parties ayant des caractéristiques physiques et chimiques identiques ou différentes. According to FIG. 3, the product is produced from an assembly formed by a covering ply and a base ply 3 in two parts having identical or different physical and chemical characteristics.

On peut par exemple choisir des couches 3a, 3b de densité différente. Comme exposé ultérieurement, on peut imprégner ces couches 3a, 3b de matière thermocollante ; cette imprégnation peut être différente d'une couche à l'autre. One can for example choose layers 3a, 3b of different density. As explained later, these layers 3a, 3b can be impregnated with heat-bonding material; this impregnation can be different from one layer to another.

Le nombre de couches composant la nappe de base 3 ne se limite pas à deux et on peut envisager également de fixer la couche 3a, alvéolaire (cellules ouvertes ou fermées) sur une couche de support rigide, ou imperméable etc. The number of layers making up the base sheet 3 is not limited to two and it is also possible to envisage fixing the layer 3a, cellular (open or closed cells) on a rigid support layer, or impermeable etc.

Suivant une autre caractéristique de l'invention (non représentée) il est possible de partir d'une nappe dite de revête ment déjà munie d'une couche alvéolaire et de limiter la couche de base à une nappe très peu alvéolaire ou mtme sans alvéole. According to another characteristic of the invention (not shown), it is possible to start from a so-called covering sheet already provided with a honeycomb layer and to limit the base layer to a sheet with very little honeycombing or even without honeycomb.

Dans ce cas, par compression et collage des alvéoles de la couche alvéolaire de la nappe de revêtement lors de la fixation sous pression de cette nappe sur la nappe de base, on obtient également l'effet de capitonnage et de matelassage équivalent à celui des modes de réalisation ci-dessus, le produit obtenu ne se distinguant pas des autres produits ci-dessus.In this case, by compression and gluing of the cells of the honeycomb layer of the covering ply during the fixing under pressure of this ply to the base ply, the quilting and quilting effect equivalent to that of the modes is also obtained. above, the product obtained not being distinguished from the other products above.

Le produit en nappes, selon le mode de réalisation de la figure 4 se compose d'une nappe de revêtement 1 qui est apparente et qui définit l'aspect extérieur du produit par sa couleur et sa texture, puis, d'une nappe de matériau de rembourrage 2 et d'une nappe de base 3. La nappe de revêtement 1 et la nappe du matériau de rembourrage 2 sont séparées par une couche 4 d'un matériau thermocollant. Il en est de même de la nappe de matériau de rembourrage 2 et de la nappe de base 3. Dans ce dernier cas, et suivant le présent exemple cette couche intermédiaire est de préférence remplacée par une imprégnation de particules de matière thermocollante dans la matière de la nappe de base 3. The sheet product, according to the embodiment of FIG. 4, consists of a coating sheet 1 which is visible and which defines the external appearance of the product by its color and texture, then, a sheet of material. of padding 2 and of a base ply 3. The covering ply 1 and the ply of padding material 2 are separated by a layer 4 of a fusible material. It is the same for the ply of padding material 2 and the base ply 3. In the latter case, and according to the present example, this intermediate layer is preferably replaced by an impregnation of particles of heat-bonding material in the material of the base sheet 3.

Dans les divers modes de réalisation, la nappe de revêtement 1 peut être constituée par une seule couche ou par la combinaison de plusieurs couches réunies les unes aux autres par contrecollage ou laminage. In the various embodiments, the covering ply 1 can be formed by a single layer or by the combination of several layers joined together by laminating or laminating.

La couche extérieure de la nappe de revêtement 1 ou la seule couche, lorsqu'il s'agit d'une nappe à couche simple est de préférence un tissu, un non tissé, une matière végétale ou artificielle tressée, etc ... suivant l'aspect extérieur que doit présenter le produit de l'invention. Lorsque cette couche extérieure fait partie d'une combinaison, par exemple à trois couches constituant la nappe de revêtement, on prévoir en plus de la nappe extérieure une couche intermédiaire, par exemple en mousse et/ou une doublure, ces trois couches étant réunies les unes aux autres par contrecollage ou par laminage. The outer layer of the covering ply 1 or the only layer, in the case of a single-ply tablecloth is preferably a woven fabric, a nonwoven, a vegetable or artificial material, etc. external appearance that the product of the invention must present. When this outer layer is part of a combination, for example with three layers constituting the covering ply, there is provided in addition to the outer ply an intermediate layer, for example of foam and / or a lining, these three layers being joined together to each other by laminating or laminating.

Il peut être intéressant de choisir comme nappe de revêtement une combinaison de trois couches, car la mousse donne du gonflant. It may be interesting to choose a combination of three layers as the covering sheet, because the foam gives bulk.

Dans le cas d'une nappe extérieure qui est un tissu léger ou un matériau à pores relativement peu serrés, il est intéressant de contrecoller sur ce tissu léger, au moins une seconde couche qui assure une certaine étanchéité ou du moins ferme les pores pour éviter que le matériau thermocollant entre la nappe de revêtement et la nappe du matériau de rembourrage ou la nappe de base ne puisse suinter à travers les pores de la couche extérieure de la nappe de revêtement. In the case of an outer layer which is a light fabric or a material with relatively small pores, it is advantageous to laminate on this light fabric, at least a second layer which ensures a certain tightness or at least closes the pores to avoid that the fusible material between the covering ply and the padding material or the base ply cannot seep through the pores of the outer layer of the covering ply.

La couche de matériau thermocollant entre la nappe de revêtement et la nappe de matériau de rembourrage ou la nappe de base est de préférence, ou suivant les applications, une couche perméable à l'air, permettant le passage de l'air-d'une face à l'autre du produit. Cette couche de matériau thermocollant peut être intégrée à la mousse de la matière expansée qui revêt la surface intérieure de la couche extérieure lorsque la nappe de revêtement est constituée par un produit combiné à deux couches sans doublure. Cette couche de matière thermocollante peut également entre constituée par la doublure de la nappe de rev#tement. The layer of fusible material between the covering ply and the padding material or the base ply is preferably, or depending on the applications, an air permeable layer, allowing the passage of air from a opposite the other of the product. This layer of fusible material can be integrated into the foam of the expanded material which coats the inner surface of the outer layer when the coating ply consists of a product combined with two layers without lining. This layer of thermobonding material can also be formed by the lining of the covering ply.

La nappe de matériau thermocollant est avantageusement constituée par un film de collage, qui présente une certaine perméabilité pour permettre la respiration ou le passage de l'air. The sheet of fusible material is advantageously constituted by a bonding film, which has a certain permeability to allow breathing or the passage of air.

Ce matériau peut être constitué par un film thermocollant comportant des trous ou des entailles. Si le produit final ne doit pas offrir cette caractéristique de perméabilité à l'air, on peut utiliser un film thermocollant non perméable.This material can be made up of a fusible film comprising holes or notches. If the final product does not have to offer this air permeability characteristic, a non-permeable fusible film can be used.

La couche de matériau de rembourrage est, de préférence, une nappe de fibres naturelles, telles que du coton et de la laine, de fibres artificielles, telles que de la viscose ou de fibres synthétiques, telles que des fibres de polyester de résine acrylique, de nylon, etc .  The layer of padding material is preferably a web of natural fibers, such as cotton and wool, artificial fibers, such as viscose, or synthetic fibers, such as polyester resin acrylic fibers, nylon, etc.

Le choix de la nature des fibres constituant la nappe de rembourrage se fait en fonction de l'application du produit. Lorsque ce produit est destiné à la fabrication de housses de revate- ments de sièges de voitures automobiles, c'est-à-dire lorsque le produit est soumis à un usage intense, il est avantageux de choisir des nappes de fibres de polyester. The choice of the nature of the fibers constituting the padding sheet is made according to the application of the product. When this product is intended for the manufacture of motor vehicle seat cover covers, that is to say when the product is subjected to intense use, it is advantageous to choose plies of polyester fibers.

Par contre, si le produit, selon-l'invention doit constituer un couvre-lit, une tige de chaussure, etc, pour lequel la caractéristique importante est celle de conserver la chaleur, alors il est avantageux de choisir une nappe de laine. On the other hand, if the product according to the invention must constitute a bedspread, a shoe upper, etc., for which the important characteristic is that of retaining heat, then it is advantageous to choose a sheet of wool.

Enfin, lorsque le produit est destiné à une utilisation comme tenture murale, il est avantageux d'utiliser de la viscose, car ce produit est relativement bon marché et du fait de son utilisation en tenture murale, il n'est pratiquement soumis à aucune action mécanique susceptible de détruire son effet de matériau de rembourrage
Le matériau de la couche de base 3 a essentiellement une fonction de support et de tenue pour donner à l'ensemble la résistance mécanique nécessaire. La nappe de base doit présenter cette caractéristique mécanique, quelles que soient les applications du produit.
Finally, when the product is intended for use as a wall hanging, it is advantageous to use viscose, since this product is relatively inexpensive and due to its use in a wall hanging, it is practically not subjected to any action. mechanical capable of destroying its effect as a cushioning material
The material of the base layer 3 essentially has a support and holding function to give the assembly the necessary mechanical resistance. The base ply must have this mechanical characteristic, whatever the applications of the product.

Il est avantageux de réaliser cette nappe de base 3 sous la forme d'une couche de mousse synthétique. Dans 1' exemple particulier choisi, on imprègne cette mousse à pores plus ou moins ouverts, de particules de matière thermocollante. On peut également remplacer cette imprégnation par une couche thermocollante disposée entre les nappes 2 et 3, comme pour la couche thermocollante entre les nappes 1 et 2. It is advantageous to produce this base ply 3 in the form of a layer of synthetic foam. In the particular example chosen, this foam with more or less open pores is impregnated with particles of fusible material. This impregnation can also be replaced by a fusible layer placed between the layers 2 and 3, as for the fusible layer between the layers 1 and 2.

Les particules imprégnant la nappe de mousse 3 sont choisies, en fonction de la température de thermocollage. Cette température dépend elle-m#me du choix des matériaux 1, 2, 3, 4 utilisés pour réaliser les produits. The particles impregnating the sheet of foam 3 are chosen, as a function of the heat-bonding temperature. This temperature itself depends on the choice of materials 1, 2, 3, 4 used to make the products.

Pour avoir le produit le plus résistant et le moins sensible aux agents extérieurs, il convient de choisir la température de thermocollage la plus élevée possible. Toutefois, cette température peut entre limitée par le choix des matériaux, tels que les matériaux des couches 1 et 2 définissant l'aspect du produit et les caractéristiques d'usure de résistance, etc ... To have the most resistant product and the least sensitive to external agents, it is advisable to choose the highest possible heat-bonding temperature. However, this temperature may be limited by the choice of materials, such as the materials of layers 1 and 2 defining the appearance of the product and the resistance wear characteristics, etc.

En fonction de ces matériaux, on choisit les matériaux thermocollants pour la couche 4 et les particules thermocollantes noyées 5 pour que le thermocollant se fasse à la température la plus élevée possible.Depending on these materials, we choose the fusible materials for layer 4 and the embedded fusible particles 5 so that the fusible is done at the highest possible temperature.

L'imprégnation de la nappe de mousse 3 par des particules thermocollantes 5 peut se faire simplement par laminage d'une nappe 3 saupoudrée de poudre ou de farine de produit thermocollant 5. En effet, à la sortie de l'intervalle de compression entre les deux cylindres, la nappe 3, qui est comprimée dans cet intervalle se dilate. Cette dilatation provoque un effet d' aspiration agissant sur les particules ou la poudre thermocollante et les aspirant à l'intérieur des pores de la mousse de la couche 3. On peut également réaliser cette imprégnation en utilisant des brosses ou des tampons s'appliquant sur la surface de la nappe à imprégner pour y faire pénétrer la poudre. Les dispositifs peuvent se substituer ou compléter les cylindres de compression décrits ci-dessus.Les particules 5 sont ainsi suffisamment retenues dans la couche 5 pour s'y accrocher lors du thermocollage tout en suintant également des pores pour se coller à la nappe 4, à travers la nappe de fibres 2. The impregnation of the sheet of foam 3 with fusible particles 5 can be done simply by rolling a sheet 3 sprinkled with powder or flour of fusible product 5. In fact, at the end of the compression interval between the two cylinders, the ply 3, which is compressed in this interval expands. This expansion causes a suction effect acting on the particles or the fusible powder and sucking them inside the pores of the foam of the layer 3. This impregnation can also be carried out using brushes or pads applied on the surface of the tablecloth to be impregnated to penetrate the powder therein. The devices can replace or supplement the compression cylinders described above. The particles 5 are thus sufficiently retained in the layer 5 to cling to it during the fusing while also oozing pores to adhere to the sheet 4, to through the fiber sheet 2.

De façon générale, la matière thermocollante peut être une matière thermoplastique ou une matière thermodurcissable. La matière peut titre du nylon, de l'éthyl-vinylacétate, des résines acrylovinyliques, etc ... ou des mélanges de ces produits et du polyéthène tel que de l'alcatène. Generally, the fusible material can be a thermoplastic or a thermosetting material. The material may be nylon, ethyl vinyl acetate, acrylovinyl resins, etc. or mixtures of these products and polyethene such as alkatene.

Outre, sa fonction de support, la nappe 3 donne également au produit, une certaine élasticité, en combinaison avec ltélasticité du matériau de rembourrage 2. In addition to its support function, the ply 3 also gives the product a certain elasticity, in combination with the elasticity of the padding material 2.

Enfin, cette nappe 3 peut compléter les caractéristiques d'isolation phonique assurées par les nappes 1 et 2, notamment dans le cas d'une nappe 2, composée de plusieurs couches. Finally, this ply 3 can supplement the sound insulation characteristics provided by the plies 1 and 2, in particular in the case of a ply 2, composed of several layers.

Le procédé de fabrication discontinu d'un produit selon l'invention sera décrit, à l'aide de la figure 5. The discontinuous manufacturing process for a product according to the invention will be described, with the aid of FIG. 5.

Selon le schéma de la figure 5, la machine pour la mise en oeuvre du procédé de l'invention se compose d'un moule 6 et d'un plateau 5.  According to the diagram in FIG. 5, the machine for implementing the method of the invention consists of a mold 6 and a plate 5.

Le moule 6 est formé d'une plaque de support 61 portant l'outil 63 par l'intermédiaire d'une nappe élastique 62. La plaque de support 61 a essentiellement une fonction mécanique de résistance à la pression de montage et de faciliter l'alimentation et l'évacuation de la machine. The mold 6 is formed of a support plate 61 carrying the tool 63 by means of an elastic ply 62. The support plate 61 essentially has a mechanical function of resistance to mounting pressure and of facilitating the supply and discharge of the machine.

La nappe élastique 62 qui est en un matériau tel qu'un feutre haute densité (par exemple une nappe d'épaisseur de 2 cm) ou une nappe de caoutchouc plein ou de mousse agglomérée, sert à absorber les irrégularités qui peuvent exister au moulage lorsque l'outil 63 rencontre une résistance localement plus forte lors de la mise en compression par le plateau 5. The elastic ply 62 which is made of a material such as a high density felt (for example a ply 2 cm thick) or a ply of solid rubber or agglomerated foam, serves to absorb the irregularities which may exist during molding when the tool 63 encounters a locally stronger resistance during the compression by the plate 5.

L'outil 63 est formé d'une plaque 631 portant des lames ou des pointes etc ... ou plus généralement des motifs 632 en fonction du dessin choisi pour le matelas sage. Les organes 632 s'opposeront à la pression exercée par le plateau 5 en lais en laissant les traces T (figure 1) et l'écrasement au moins partiel permanent de la matière alvéolaire. The tool 63 is formed of a plate 631 carrying blades or points etc ... or more generally patterns 632 according to the design chosen for the wise mattress. The members 632 will oppose the pressure exerted by the plate 5 in blanks leaving the traces T (FIG. 1) and the permanent at least partial crushing of the cellular material.

Le plateau 5 est de préférence une plaque lisse sur sa face en regard des organes 632. Cette surface est de préférence un revêtement d'un matériau anti-adhérent aux températures de fonctionnement de la machine (par exemple revêtement de Teflon (marque déposée)
Suivant une caractéristique avantageuse, le plateau 5 est mobile verticalement et le moule 6 est mobile horizontalement.
The plate 5 is preferably a smooth plate on its face opposite the members 632. This surface is preferably a coating of a non-stick material at the operating temperatures of the machine (for example Teflon coating (registered trademark)
According to an advantageous characteristic, the plate 5 is movable vertically and the mold 6 is movable horizontally.

Bien que le moule 5 ou le plateau 6 puisse être chauffé, il est intéressant de limiter le chauffage au seul plateau 6. En effet, on obtient un chauffage plus régulier et plus constant quelles que soient les conditions de fonctionnement de la machine.Although the mold 5 or the plate 6 can be heated, it is advantageous to limit the heating to the only plate 6. In fact, a more regular and more constant heating is obtained whatever the operating conditions of the machine.

Si le moule et par suite surtout les organes 632 sont chauffés, le profil des températures est très variable ou il est difficile de le maintenir uniforme, car les organes 632 jouent le rôle d'ailettes de refroidissement ; le moindre courant d'air refroidit plus fortement les ailettes au bord du moule et détruit l'uniformité de la température du moule. Par contre, si l'on utilise (ou limite) le chauffage au plateau 5, on obtient une température très régulière d'autant plus que le chauffage peut se faire à l'aide d'un fluide thermique chauffé par exemple par des résistances électriques ; il est alors avantageux de faire circuler ce fluide pour uniformiser encore plus sa température et par suite celle du plateau. D'autres moyens de chauffage tels que des résistances électriques agissant directement sur le plateau ou de la vapeur peuvent également d'utiliser. If the mold and consequently especially the organs 632 are heated, the temperature profile is very variable or it is difficult to keep it uniform, since the organs 632 act as cooling fins; the slightest air stream cools the fins more strongly at the edge of the mold and destroys the uniformity of the mold temperature. On the other hand, if one uses (or limits) the heating to the plate 5, one obtains a very regular temperature all the more that the heating can be done using a thermal fluid heated for example by electrical resistances ; it is then advantageous to circulate this fluid to standardize its temperature even more and consequently that of the plate. Other heating means such as electric resistances acting directly on the plate or steam can also be used.

Le chauffage par le seul plateau offre en outre l'avantage d'entre moins dangereux pour la nappe de revêtement (qui est souvent, le matériau le plus sensible du produit à réaliser) car cette nappe est située du côté de la partie froide (moule 6) et non pas de la partie chaude (plateau 5). Heating by the tray alone also offers the advantage of being less dangerous for the covering sheet (which is often the most sensitive material of the product to be produced) because this sheet is located on the side of the cold part (mold 6) and not the hot part (plate 5).

La fabrication se déroule de la façon suivante
On dispose à l'intérieur du moule 6 et les diverses couches, puis, on referme le moule 6 en faisant descendre le couvercle 5. Les organes 632 viennent alors s'appliquer sous pression sur les couches et les compriment localement sur la plaque 5. La matière se déploit librement entre les organes de pression, sans entre soumise à la pression.
Manufacturing takes place as follows
The mold 6 and the various layers are placed inside, then the mold 6 is closed by lowering the cover 5. The members 632 are then applied under pressure to the layers and compress them locally on the plate 5. The material deploys freely between the pressure members, without entering under pressure.

En meme temps que l'on exerce de la pression, on chauffe les matériaux placés dans le moule pour amener la température des matériaux thermocollants à la température de fusion ou de thermocollage
Suivant les matériaux 4, 5 utilisés, on maintient la température et la pression pendant un temps déterminé, Jusqu'au collage de la surface inférieure de la nappe de revêtement 1 sur la gurface supérieure de la nappe de base 3, de façon que la matière thermocollante 4 vienne se fixer sur les particules 5 noyées et accrochées, au moins partiellement, dans les cavités de la matière de la couche 3 en collant également les alvéoles comprimées au droit des organes 633 (trace T, zone T) ;; ces matériaux thermocollants de la couche 4 et les particules thermocollantes 5 se rejoignent à travers la couche de fibres 2, au niveau de la zone d'action des organes de pression 9,9'.
At the same time as pressure is exerted, the materials placed in the mold are heated to bring the temperature of the fusible materials to the melting or fusing temperature.
Depending on the materials 4, 5 used, the temperature and the pressure are maintained for a determined time, until the lower surface of the covering ply 1 is bonded to the upper gurface of the base ply 3, so that the material fusible 4 comes to be fixed on the particles 5 drowned and hung, at least partially, in the cavities of the material of the layer 3 while also sticking the compressed alveoli at the level of the organs 633 (trace T, zone T); these fusible materials of layer 4 and the fusible particles 5 come together through the layer of fibers 2, at the level of the zone of action of the pressure members 9, 9 ′.

Après ce traitement à la température et à la pression adéquates, choisies en fonction des matériaux constituant les diverses couches 1, 4, 2, 3, 5, on ouvre le moule et on enlève le produit matelassé et capitonné. After this treatment at the appropriate temperature and pressure, chosen according to the materials constituting the various layers 1, 4, 2, 3, 5, the mold is opened and the padded and padded product is removed.

L'opération discontinue, décrite ci-dessus peut également se faire dans une installation en continu. Le choix d'une installation en continu ou d'une installation fonctionnant, de façon discontinue, dépend essentiellement des dimensions des motifs du capitonnage à réaliser sur les matériaux. En effet, si ces motifs sont de grandes dimensions et ne répètent pas suffisamment fréquemment, on aboutirait, dans le cas dlune installation continue à des dimensions de cylindres trop grandes pour entre réalisables en pratique. Dans ce cas, on choisira une fabrication pièce par pièce, de façon discontinue. Par contre, si les dimensions des motifs sont relativement faibles, on choisira le fonctionnement continu. The discontinuous operation, described above, can also be done in a continuous installation. The choice of a continuous installation or an installation operating discontinuously depends essentially on the dimensions of the upholstery patterns to be made on the materials. Indeed, if these patterns are large and do not repeat frequently enough, it would lead, in the case of a continuous installation to cylinder dimensions too large to be achievable in practice. In this case, we will choose a piece by piece manufacturing, discontinuously. On the other hand, if the dimensions of the patterns are relatively small, the continuous operation will be chosen.

Dans tous les cas, il peut titre intéressant de préchauffer les nappes, par exemple dans un tunnel de chauffage à du chaud, à rayons infra-rouge ou à micro-ondes, en amont de la compression. In all cases, it may be advantageous to preheat the layers, for example in a heating tunnel with heat, infrared rays or microwaves, upstream of the compression.

Enfin, le choix entre le fonctionnement continu et le fonctionnement discontinu dépend de la température et du temps de maintien en pression, pour arriver à une fixation définitive de la forme capitonnée. Si, suivant les matériaux utilisés, il faut exercer la pression et la température pendant un temps relativement long, il ne sera pas possible de fonctionner en continu, car le temps de séjour entre les cylindres reste nécessairement limité meme si les cylindres tournent lentement et sont de grand diamètre. Finally, the choice between continuous operation and discontinuous operation depends on the temperature and the pressure maintenance time, to arrive at a definitive fixation of the padded shape. If, depending on the materials used, pressure and temperature have to be exerted for a relatively long time, it will not be possible to operate continuously, since the residence time between the cylinders necessarily remains limited even if the cylinders rotate slowly and are large diameter.

Dans le cas d'une installation en continu, les cylin- dres comportent, en relief, des organes de pression dont le dessin correspond au motif à réaliser sur le produit de revêtement de 1' invention
Les produits selon l'invention ont de multiples applications dans le domaine du revêtement de sièges, la fabrication de housses pour sièges et banguettes d'automobiles, produits de revêtement pour l'ameublement, comme tenture murale, etc
A titre d'exemple, il est particulièrement avantageux d'utiliser le produit selon l'invention pour la fabrication d'articles chaussants notamment d'articles chaussants de fantaisie tels que des bottes, comme les après-ski. Dans ce cas, comme la botte doit entre étanche à l'eau, on peut à la fabrication du produit formant la tige, prévoir des dessins tels que des surpiqures prises dans la masse sans qu'il soit nécessaire de surpiquer cette matière synthétique, comme cela est actuellement le cas car cela rend la botte perméable.
In the case of a continuous installation, the cylinders comprise, in relief, pressure members whose design corresponds to the pattern to be produced on the coating product of the invention
The products according to the invention have multiple applications in the field of seat upholstery, the manufacture of covers for seats and banguettes for automobiles, upholstery products for furniture, such as wall hangings, etc.
By way of example, it is particularly advantageous to use the product according to the invention for the manufacture of footwear, in particular fancy footwear such as boots, such as après-ski. In this case, as the boot must be watertight, it is possible to manufacture the product forming the upper, to provide designs such as stitching taken in the mass without the need to overstitch this synthetic material, such as this is currently the case as it makes the boot permeable.
