Abstract

The invention relates to a device permitting the preforming of fabric preforms and then the shaping of the fabric on the walls of the mould, the said device being characterised in that it includes a mould made from two parts, the upper part 1 of which, fixed to a casing 2 in which a partial vacuum may be created, carries, on its periphery, a device permitting the preforming of preforms. The lower part 4 moves inside the casing and bears against the upper part during the final shaping of the fabric on the walls of the mould. The device according to the invention is particularly intended for the production of cushions made from plastic foam having integrated covers for motor vehicles and furnishing.

Description

Dans son brevet n0 7401 274, le demandeur a décrit un procédé de fabrication de coussins de mousse de polyuréthane à housse intégrée en tissu, comportant notamment la préfabrication d'une ébauche de housse obtenue par contraction périmé trique sans allongement des fibres dudit tissu, ladite ébauche étant destinée à être travaillée ensuite par formage sous vide, à froid ou à chaud suivant le cas, en mettant en oeuvre les possibilités d'allongement des fils constituant le tissu en question. In its patent No. 7401 274, the applicant has described a process for the manufacture of polyurethane foam cushions with an integrated fabric cover, comprising in particular the prefabrication of a cover blank obtained by expired contraction within the length of the fibers of said fabric, said fabric blank being intended to be worked then by vacuum forming, cold or hot as appropriate, using the possibilities of elongation of the son constituting the fabric in question.

Conformément au procédé décrit dans ledit brevet, ladite contraction périmé trique est obtenue en plaçant le tissu destine à former ladite ébauche, entre les deux parties d'un cadre non sérré, permettant de provoquer, par emboutissage limité, un glissement dudit tissu au niveau et au voisinage dudit cadre, avec contraction de ce tissu périphérique, et sans allongement des fils constituant ledit tissu, cette opération d'emboutissage étant arrêtée avant qu'il puisse se produire un tel allongement, et juste avant qu'il se forme des plis au voisinage desdits cadres, notamment dans les angles lorsque ledit cadre est de forme générale rectangulaire ou trapézoidale, comme c'est le cas dans certaines fabrications de coussins à housse intégrée pour véhicules automobiles. In accordance with the method described in said patent, said perimeter contraction is obtained by placing the fabric intended to form said blank, between the two parts of a non-tight frame, making it possible to cause, by limited drawing, a sliding of said fabric at the level and in the vicinity of said frame, with contraction of this peripheral fabric, and without elongation of the threads constituting said fabric, this drawing operation being stopped before such elongation can occur, and just before it forms folds at the vicinity of said frames, in particular in the angles when said frame is of generally rectangular or trapezoidal shape, as is the case in certain manufacture of cushions with integrated cover for motor vehicles.

Dans sa demande de premier certificat d'addition, 7412661 le demandeur a décrit un procédé perfectionné comportant, pour chaque tissu utilisé, la détermination préalable, au moyen d'un cadre de forme circulaire, d'un coefficient de contraction périmétrique maximale du tissu considéré, et celle ultérieure- d'un coefficient de contraction périmétrique optimale à adopter en pratique pour limiter le préformage de ladite ébauche. In his request for the first addition certificate, 7412661 the applicant described an improved process comprising, for each fabric used, the prior determination, by means of a circular frame, of a coefficient of maximum perimeter contraction of the tissue considered , and the subsequent one- of an optimal perimeter contraction coefficient to be adopted in practice to limit the preforming of said blank.

Ledit procédé est caractérisé par la prévision, dans les cadres utilisés pour ce préformage, de fentes dans lesquelles coulissent des aiguilles de guidage du tissu, et dont la longueur et l'orientation sont adaptées an fonction de ce coefficient de contraction périmétrique optimale, de telle façon qu'au moment où lesdites aiguilles viennent en butée contre les extrémités desdites fentes voisines de la partie interne de dimensions réduites desdits cadres, ce coefficient soit atteint sans être dépassé. Said method is characterized by the provision, in the frames used for this preforming, of slots in which slide needles for guiding the fabric, and the length and orientation of which are adapted as a function of this coefficient of optimal perimeter contraction, such so that when said needles abut against the ends of said slots adjacent to the inner part of reduced dimensions of said frames, this coefficient is reached without being exceeded.

Dans sa demande de brevet 8407#40, le demandeur a décrit un dispositif perfectionné permettant de guider avec précision le tissu pen dant son glissement dans le moule, de façon à obtenir le coefficient de contraction périmétriqu ridéal pour le tissu utilisé.  In its patent application 8407 # 40, the applicant described an improved device making it possible to precisely guide the fabric during its sliding in the mold, so as to obtain the coefficient of perimetric contraction rideal for the fabric used.

En appliquant le procédé décrit dans le brevet principal,7401274#, son premier certificat d'addition 7412661 et la demande de brevet 8407840, on forme une ébauche en tissu avec un dispositif approprié et on place ensuite cette ébauche sur le moule contre les parois duquel elle est appliquée par dépression avant d'être emplie de mousse plastique pour réaliser un coussin à housse intégrée en tissu. By applying the process described in the main patent, 7401274 #, its first certificate of addition 7412661 and patent application 8407840, a fabric blank is formed with an appropriate device and this blank is then placed on the mold against the walls of which it is applied by vacuum before being filled with plastic foam to make a cushion with an integrated fabric cover.

La manipulation de l'ébauche entre le dispositif sur lequel elle est formée et le moule est une opération qui consomme du temps et de la main-d'oeuvre. The manipulation of the blank between the device on which it is formed and the mold is an operation which consumes time and manpower.

La présente invention a#pour but de pallier cet inconvénient. The object of the present invention is # to overcome this drawback.

La présente invention est relative à un dispositif perfectionné permettant successivement de réaliser une -ébauche en tissu en utilisant les procédés et dispositifs décrits dans le brevet 7401274, son premier certificat d'addition 7412661 et la demande de brevet 8407840, et de mettre ladite ébauche en forme sur les parois du moule. The present invention relates to an improved device making it possible successively to produce a fabric blank using the methods and devices described in patent 7401274, its first certificate of addition 7412661 and patent application 8407840, and to put said blank form on the walls of the mold.

Le dispositif est caractérisé par un moule en deux parties représenté sur les figures 1 à 4. The device is characterized by a two-part mold shown in Figures 1 to 4.

La partie supérieure (1) comprend les c8tés du moule et le cadre sur lequel est placé le dispositif permettant de réaliser la contraction périmétrique optimale du tissu conformément au procédé décrit dans le brevet 7401274, son premier certificat d'addition 7412661 et la demande de brevet 8407840. Sur les figures 1 à 4 est représente le dispositif à lames décrit dans la demande de brevet 840784.  The upper part (1) comprises the sides of the mold and the frame on which is placed the device allowing the optimal perimeter contraction of the fabric to be carried out in accordance with the process described in patent 7401274, its first certificate of addition 7412661 and the patent application. 8407840. In Figures 1 to 4 is shown the blade device described in patent application 840784.

Sur la partie supérieure (1) est fixé, d'une manière étanche, un caisson(2) muni d'un orifice (3). On the upper part (1) is fixed, in a sealed manner, a box (2) provided with an orifice (3).

La partie inférieure (4) du moule est placée à l'intérieur du cais- son (2) et peut se déplacer pour venir s'appliquer contre la partie supérieure du moule (1). Son déplacement peut titre réalisé par n'importe quel moyen approprié; le dispositif représente sur les figures 1 à 4 est un verin hydraulique (5). The lower part (4) of the mold is placed inside the box (2) and can move so as to bear against the upper part of the mold (1). Its displacement can title carried out by any suitable means; the device shown in Figures 1 to 4 is a hydraulic cylinder (5).

Dans la mise en oeuvre du procédé faisant l'objet de la présente invention, on place un tissu (6) sur la partie supérieure du moule (1) et on met en place les lames (7) ayant pour rôle de guider le tissu pendant son entrée dans le moule de façon à obtenir la contraction périmétrique optimale du tissu sur tout le périmètre du moule. In the implementation of the process which is the subject of the present invention, a fabric (6) is placed on the upper part of the mold (1) and the blades (7) having the role of guiding the fabric during its entry into the mold so as to obtain the optimal perimeter contraction of the fabric over the entire perimeter of the mold.

La partie inférieure (4) du moule est alors à sa position la plus basse dans le caisson (2). Figure 1. On met alors le caisson (2) en dépression en reliant l'orifice (3) à une pompe à vide par exemple. The lower part (4) of the mold is then in its lowest position in the box (2). Figure 1. The casing (2) is then placed under vacuum by connecting the orifice (3) to a vacuum pump for example.

Sous l'effet de la dépression, le tissu(6) glisse entre la partie supérieure du moule (1) et les lames (7) et entre le moule où il forme une ébauche tout en se contractant sur le périmètre du moule et en s'étirant s'il s'agit d'un tissu élastique.Under the effect of the depression, the fabric (6) slides between the upper part of the mold (1) and the blades (7) and between the mold where it forms a blank while contracting on the perimeter of the mold and in s stretching if it is an elastic fabric.

Lorsque la contraction périmétrique optimale est obtenue, on réduit la dépression dans le caisson (2) de façon à laisser le tissu reprendre sa position naturelle. On peut laisser persister dans le caisson (2) une petite dépression de façon à ce que l'ébauche soit légèrement tendue pour éviter les plis. On déplace alors la partie inférieure du moule (4) jusqu'à ce qu'elle vienne en contact avec la partie supérieure du moule (i) et on met le caisson (2) en dépression de façon à appliquer le tissu (6) sur toute la surface du moule. When the optimal perimeter contraction is obtained, the depression in the box (2) is reduced so as to allow the fabric to return to its natural position. You can leave a small depression in the box (2) so that the blank is slightly stretched to avoid creases. Then move the lower part of the mold (4) until it comes into contact with the upper part of the mold (i) and put the box (2) in vacuum so as to apply the fabric (6) on the entire surface of the mold.

Le figure 1 représente le moule sur lequel le tissu (6) a été placé. La partie inférieure (4) du moule est en position basse. Figure 1 shows the mold on which the fabric (6) was placed. The lower part (4) of the mold is in the low position.

La Figure 2 représente le même dispositif au moment où une dépression a été créée dans le caisson (2). Le tissu (6) est entré dans le moule et s'est, de plus, légèrement distendu. Figure 2 shows the same device when a depression was created in the box (2). The fabric (6) entered the mold and, moreover, slightly distended.

Sur la Figure 3, la dépression a été fortement diminuée dans le caisson (2) et l'ébauche du tissu (6) est revenue, grâce à son élasticité, à ses dimensions normales. Elle reste légèrement tendue et sans plis grâce à une légère dépression maintenue dans le caisson (2). Le partie inférieure du moule (4) est en train de remonter vers la partie supérieure du moule (1). In Figure 3, the vacuum has been greatly reduced in the box (2) and the blank of the fabric (6) has returned, thanks to its elasticity, to its normal dimensions. It remains slightly taut and without wrinkles thanks to a slight depression maintained in the box (2). The lower part of the mold (4) is going up towards the upper part of the mold (1).

Le Figure 4 représente le dispositif au moment où les parties sup érieure (1) et inférieure (4) du moule sont en contact et le tissu (6) appliqué par dépression sur les parois du moule.  Figure 4 shows the device when the upper (1) and lower (4) parts of the mold are in contact and the fabric (6) applied by vacuum to the walls of the mold.
