Abstract
Description
Procédé de fabrication d'un article de lingerie et article de lingerie en résultant
La présente invention concerne un article de lingerie, tel qu'une coque, un ampli ou un dessous de sein pour soutiengorge, à base d'une mousse à haut poids moléculaire et son procédé de moulage par thermoformage.Method for manufacturing a lingerie article and resulting lingerie article
The present invention relates to an article of lingerie, such as a shell, an amplifier or an under breast for a bra, based on a high molecular weight foam and its thermoforming molding process.
Les articles de lingerie tels que les dessous de sein, les amplis ou les coques destinés à être incorporés dans des soutien-gorges présentent une forme courbe ou un galbe. Ce galbe peut être obtenu de diverses manières. La technique la plus classique consiste à réaliser ce galbe par décolletage d'un pain de mousse de manière à réaliser un cône puis ce cône, qui peut être découpé ou non, est aminci au niveau de ses bords et ensuite habillé sur ses deux faces par un tissu fixé sur chacune des faces dudit cône par surfilage.Lingerie items such as under breasts, amplifiers or shells intended to be incorporated into bras have a curved or curved shape. This curve can be obtained in various ways. The most classic technique consists in making this curve by turning a foam bar so as to make a cone then this cone, which can be cut or not, is thinned at its edges and then dressed on both sides by a fabric fixed to each of the faces of said cone by overcasting.
Cependant, un tel procédé de fabrication est coûteux et nécessite un grand nombre d'opérations. En outre, les formes susceptibles d'être réalisées sont limitées en raison du coût de l'outillage.However, such a manufacturing process is expensive and requires a large number of operations. In addition, the shapes that can be produced are limited due to the cost of the tools.
Une autre technique consiste à utiliser une grille plastique revêtue sur chacune de ses faces d'un tissu extensible, le tissu étant collé sur ladite grille après déformation de cette dernière de manière à obtenir la forme désirée. Un tel procédé, même s'il permet d'obtenir des formes variées, est peu appliqué en raison du fait qu'il ne permet pas d'obtenir des articles de lingerie confortables. En effet, les tissus utilisés sont généralement des tissus fins à travers lesquels la grille peut se sentir rendant le port de l'article inconfortable.Another technique consists in using a plastic grid coated on each of its faces with an extensible fabric, the fabric being glued to said grid after deformation of the latter so as to obtain the desired shape. Such a process, even if it makes it possible to obtain various shapes, is little applied due to the fact that it does not make it possible to obtain comfortable lingerie articles. Indeed, the fabrics used are generally fine fabrics through which the grid can feel making the wearing of the article uncomfortable.
Le but de la présente invention est donc de proposer un procédé de fabrication d'un article de lingerie que permette l'obtention d'un article de lingerie qui, d'une part soit confortable et donc réalisé à partir d'une mousse à haut poids moléculaire, d'autre part soit susceptible d'affecter un grand nombre de formes sans augmenter son court de fabrication.The object of the present invention is therefore to propose a method of manufacturing an article of lingerie which makes it possible to obtain an article of lingerie which, on the one hand, is comfortable and therefore produced from a high foam. molecular weight, on the other hand is likely to affect a large number of forms without increasing its manufacturing time.
L'invention concerne à cet effet un procédé de moulage par thermoformage d'articles, à base d'une mousse à haut poids moléculaire telle qu'une mousse polyester, polyéther ou polyuréthanne, en particulier d'articles de lingerie, tels que coque, ampli ou dessous de sein susceptibles d'être incorporés dans un soutien-gorge et présentant des formes courbes ou galbées, caractérisé en ce qu'on dispose entre deux couches de mousse un insert en matière plastique thermofusible, en ce qu'on chauffe la pile à une température proche de la température de fusion de l'insert, en ce qu'on dispose la pile ainsi chauffée dans un moule en deux parties de manière à affecter à la pile, lors de la fermeture du moule, la forme désirée.To this end, the invention relates to a process for thermoforming molding of articles, based on a high molecular weight foam such as a polyester, polyether or polyurethane foam, in particular of lingerie articles, such as shell, amp or under breast capable of being incorporated into a bra and having curved or curved shapes, characterized in that there is between two layers of foam an insert of hot-melt plastic, in that the battery is heated at a temperature close to the melting temperature of the insert, in that the stack thus heated is placed in a mold in two parts so as to assign to the stack, when the mold is closed, the desired shape.
Selon un mode de mise en oeuvre préféré de l'invention, on chauffe la pile par pressage entre deux plaques chauffantes.According to a preferred embodiment of the invention, the cell is heated by pressing between two heating plates.
L'invention concerne également un article de lingerie tel que coque, ampli ou dessous de sein pour soutien-gorge à base de mousse à haut poids moléculaire, caractérisé en ce qu'il est constitué d'au moins l'empilement successif d'une couche de mousse, d'un insert et d'une couche de mousse solidarisés entre eux par chauffage et conformés par moulage.The invention also relates to an item of lingerie such as shell, amplifier or under breast for a bra based on high molecular weight foam, characterized in that it consists of at least the successive stacking of a layer of foam, an insert and a layer of foam joined together by heating and shaped by molding.
L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation.The invention will be clearly understood on reading the following description of exemplary embodiments.
Pour la mise en oeuvre du procédé de moulage, objet de l'invention, on dispose au départ généralement de trois rouleaux sur lesquels sont enroulées les matières devant être empilées. Deux rouleaux comportent une matière identique, à savoir une mousse à haut poids moléculaire telle qu'une mousse polyester, polyéther ou polyuréthanne se présentant sous forme d'une nappe bobinée. A cette mousse peut avoir été préalablement associé par contre-collage sur l'une des faces de cette mousse un tissu tel qu'un tissu synthétique du type polyamide, polyacrylique, jersey ou un coton qui constituera la couche apparente dudit article de lingerie. Un troisième rouleau supporte quant à lui le matériau constitutif de l'insert se présentant là encore sous forme d'un film. Cet insert est généralement réalisé en matière plastique vinylique par exemple de l'éthyle vinylacétate et se présente souvent sous forme d'une grille alvéolaire. L'intérêt des orifices dans l'insert est de faciliter la fusion de la matière et son fluage en direction de la mousse de manière à permettre, lors du chauffage, une meilleure adhésion des couches entre elles.For the implementation of the molding process, object of the invention, there are generally available from the start three rollers on which are wound the materials to be stacked. Two rolls comprise an identical material, namely a high molecular weight foam such as a polyester, polyether or polyurethane foam in the form of a wound sheet. This foam may have been previously associated by laminating on one of the faces of this foam a fabric such as a synthetic fabric of the polyamide, polyacrylic, jersey or cotton type which will constitute the visible layer of said lingerie article. A third roller supports the material constituting the insert, again in the form of a film. This insert is generally made of vinyl plastic, for example ethyl vinyl acetate and is often in the form of a cellular grid. The advantage of the orifices in the insert is to facilitate the melting of the material and its creep in the direction of the foam so as to allow, during heating, better adhesion of the layers to each other.
Ces trois rouleaux sont disposés de manière à ce qu'on puisse dérouler de manière simultanée deux couches de mousse et une couche d'insert de manière à pouvoir les passer entre des plaques chauffantes disposées en aval desdits rouleaux. Ainsi, les éléments de la pile arrivent entre les plaques chauffantes à l'état empilé.These three rollers are arranged so that two layers of foam and one layer of insert can be unrolled simultaneously so that they can be passed between heating plates arranged downstream of said rollers. Thus, the elements of the stack arrive between the heating plates in the stacked state.
Les plaques chauffantes sont montées solidaires d'organes d'actionnement de manière à pouvoir être animées d'un mouvement vertical de manière analogue à des plateaux de presse de telle sorte qu'une fois portées à température, ces plaques chauffantes viennent se plaquer contre les deux faces opposées de ladite pile et restent en contact avec cette dernière pendant un temps suffisant pour permettre le chauffage et le ramollissement de l'insert. Lors de son ramollissement, l'insert vient se lier avec les éléments constitutifs des couches contigües, à savoir les couches de mousse. Généralement, lorsqu'on utilise une mousse en polyuréthanne, le temps de chauffage est de l'ordre de 20 secondes et la température des plaques chauffantes de l'ordre de 145 degrés. Par la suite, la pile ainsi chauffée est introduite dans un moule en deux parties. Le moule est alors fermé de manière à affecter à la pile la forme désirée. Une fois l'opération de moulage terminée, la pile est extraite du moule puis découpée aux dimensions voulues. Par une découpe au laser, on peut éviter l'opération de surfilage. Pour des raisons esthétiques mais également techniques, les couches de mousse de part et d'autre de l'insert sont généralement d'épaisseur similaire. Quant au tissu qui sera éventuellement collé sur la face externe apparente de la couche de mousse, il sera fonction de la destination du produit. On pourra également prévoir de chauffer dans un premier temps une couche de mousse et l'insert pour rendre l'insert moulable puis de venir disposer dans un second temps la couche de mousse avant de disposer l'ensemble dans un moule. On introduit dans ce cas cependant une étape supplémentaire qui présente peu d'intérêt.The heating plates are mounted integral with actuating members so as to be able to be driven in a vertical movement in a manner analogous to press plates so that once brought to temperature, these heating plates are pressed against the two opposite faces of said stack and remain in contact with the latter for a time sufficient to allow heating and softening of the insert. During its softening, the insert comes to bond with the constituent elements of the contiguous layers, namely the layers of foam. Generally, when a polyurethane foam is used, the heating time is around 20 seconds and the temperature of the hot plates around 145 degrees. Subsequently, the stack thus heated is introduced into a two-part mold. The mold is then closed so as to assign the desired shape to the stack. Once the molding operation is complete, the stack is extracted from the mold and then cut to the desired dimensions. By laser cutting, the overcasting operation can be avoided. For aesthetic but also technical reasons, the layers of foam on either side of the insert are generally of similar thickness. As for the fabric which will eventually be glued to the visible external face of the foam layer, it will depend on the destination of the product. Provision may also be made to heat a layer of foam and the insert in order to make the insert moldable, and then to arrange the layer of foam in a second step before placing the assembly in a mold. In this case, however, an additional step is introduced which is of little interest.
Grâce à ce procédé de moulage par thermoformage, on peut réaliser des coques, des amplis ou des dessous de sein en mousse, donc confortables, qui affectent la forme désirée.Thanks to this thermoforming molding process, it is possible to make shells, amplifiers or undersides of foam, therefore comfortable, which affect the desired shape.
Bien évidemment, les compositions des couches de mousse et de l'insert peuvent varier. Ainsi, à titre d'exemple, la mousse peut être une mousse à cellules fermées, ce qui empêche la pénétration de l'eau à l'intérieur de celle-ci. De préférence, la mousse est traitée anti-UV afin d'éviter le jaunissement (par exemple marque déposée BULFAST S).Obviously, the compositions of the foam layers and of the insert may vary. Thus, by way of example, the foam may be a closed cell foam, which prevents the penetration of water inside it. Preferably, the foam is anti-UV treated to avoid yellowing (for example registered trademark BULFAST S).
De même, l'insert est une matière plastique, constituée par exemple sous forme d'une grille alvéolaire ou d'un film perforé de même caractéristique que la grille alvéolaire. Likewise, the insert is a plastic material, constituted for example in the form of a cellular grid or of a perforated film with the same characteristic as the cellular grid.
Grâce à un tel procédé de fabrication, tout l'outillage spécifique qui était utilisé dans le cas des opérations de décolletage est supprimé. En outre, les temps de fabrication deviennent particulièrement courts. Thanks to such a manufacturing process, all the specific tools which were used in the case of bar turning operations are eliminated. In addition, manufacturing times become particularly short.
