Description

Dispositif de formage d'un support textile et procédé de formage associé. Apparatus for forming a textile support and associated forming method
L'invention concerne le domaine des dispositifs de formage d'un support textile enduit d'une couche de matière plastique et les procédés de formage du support textile. The invention relates to the field of devices for forming a textile support coated with a layer of plastic material and processes for forming the textile support.
On connaît du document FR2761293 Bl un procédé de fabrication pour la fabrication d'un objet tridimensionnel souple en forme constitué d'un support textile enduit d'une couche de matière plastique. Le procédé de fabrication propose le maintien dans un cadre d'un textile qui est chauffé sur une face par un chauffage radiant à rampe infrarouge. Puis on vient déformer le textile chauffé par thermo- compression ou thermoformage. Ce type de procédé ne permet pas le réglage et le maintien d'une température précise en fonction des conditions extérieures. En outre, il n'y a pas d'homogénéité de la répartition de chaleur sur le format textile ce qui empêche une déformation uniforme du support textile.  Document FR2761293 B1 discloses a manufacturing method for manufacturing a flexible three-dimensional object in the form of a textile support coated with a layer of plastics material. The manufacturing process proposes the maintenance in a frame of a textile which is heated on one side by a radiant heating with infrared ramp. Then we deform the heated textile by thermo-compression or thermoforming. This type of process does not allow the setting and the maintenance of a precise temperature according to the external conditions. In addition, there is no homogeneity of the heat distribution on the textile format which prevents uniform deformation of the textile support.
Il est à noter que le support textile utilisé se dégrade facilement en cas d'excès de chaleur sur une de ses faces ce qui entraine des décolorations, une dégradation de ses performances, délamination des couches, etc.  It should be noted that the textile support used degrades easily in case of excess heat on one of its faces which causes discoloration, degradation of its performance, delamination of layers, etc.
L'invention a pour but de remédier à tout ou partie des inconvénients précités.  The object of the invention is to remedy all or some of the aforementioned drawbacks.
L'invention a pour objet un dispositif de formage d'un support textile enduit d'au moins une couche de matière plastique comprenant:  The subject of the invention is a device for forming a textile support coated with at least one layer of plastics material comprising:
- au moins un poste de chauffage au niveau duquel le support textile est chauffé jusqu'à une température déterminée,  at least one heating station at which the textile support is heated to a predetermined temperature,
- au moins un poste de formage comprenant au moins un outil de déformation, et au niveau duquel le support textile chauffé est déformé par application du au moins un outillage de déformation conformé à une forme déterminée,  at least one forming station comprising at least one deformation tool, and at which the heated textile support is deformed by applying the at least one deformation tool shaped to a specific shape,
caractérisé en ce que le dispositif de formage comprend au niveau du poste de formage au moins un organe de stabilisation et de maintien de la température atteinte au niveau du poste de chauffage.  characterized in that the forming device comprises at the forming station at least one stabilization member and maintaining the temperature reached at the heating station.
L'organe de stabilisation et de maintien de température, fournit un chauffage réparti et réglable du support textile à déformer permettant une déformation homogène du support textile, et permet de pallier la très faible inertie thermique du support textile à déformer.  The stabilizing and temperature-maintaining member provides a distributed and adjustable heating of the textile support to be deformed, allowing uniform deformation of the textile support, and makes it possible to overcome the very low thermal inertia of the textile support to be deformed.
Selon une caractéristique de l'invention, le au moins un organe de stabilisation et de maintien de température est configuré pour chauffer le support textile de manière réglable. Ainsi, la température est déterminée et réglée en fonction des propriétés du support textile et de ses faces. According to one characteristic of the invention, the at least one stabilization and temperature-maintaining member is configured to heat the support adjustable textile. Thus, the temperature is determined and adjusted according to the properties of the textile support and its faces.
Selon une caractéristique de l'invention, le au moins un organe de stabilisation et de maintien de température est configuré pour chauffer additionnellement en périphérie du support textile juste avant la pénétration de la matière du support textile en zone de déformation plastique maximale.  According to one characteristic of the invention, the at least one stabilizing and temperature-maintaining member is configured to heat additionally at the periphery of the textile support just before the material of the textile support penetrates into a zone of maximum plastic deformation.

Ainsi, une face du support peut être chauffée à une première température et la deuxième face du support textile peut être chauffée à une deuxième température, le chauffage est tout de même homogène puisque les deux faces sont chauffées en même temps. En outre, plusieurs portions d'une même face de support textile peuvent recevoir un chauffage à des températures différentes, le chauffage reste homogène dans la mesure où les deux faces du support textile sont traitées en même temps.  In the present application, homogeneous heating means heating distributed over the entire surface of each face of the textile support and the faces of the textile support are heated simultaneously. Thus, one side of the support can be heated to a first temperature and the second face of the textile support can be heated to a second temperature, the heating is still homogeneous since both sides are heated at the same time. In addition, several portions of the same textile support face can receive heating at different temperatures, the heating remains homogeneous to the extent that the two faces of the textile support are treated at the same time.

Selon une caractéristique de l'invention, le dispositif de formage comprend en outre au moins un organe de transfert configuré pour transférer le support textile chauffé du poste de chauffage vers le poste de formage. Cet organe de transfert permet une translation rapide du support textile depuis le poste de chauffage vers le poste de formage. Le transfert du support textile se doit d'être rapide afin de conserver le support textile à une température permettant sa déformation à chaud. According to one characteristic of the invention, the forming device further comprises at least one transfer member configured to transfer the heated textile support from the heating station to the forming station. This transfer member allows a fast translation of the textile support from the station of heating to the forming station. The transfer of the textile support must be fast in order to keep the textile support at a temperature allowing its hot deformation.
Selon une caractéristique de l'invention, l'organe de transfert est configuré pour se déplacer en translation entre au moins le poste de chauffage et le poste de formage.  According to a characteristic of the invention, the transfer member is configured to move in translation between at least the heating station and the forming station.
