Description

La présente invention a trait à un procédé pour le transfert par sublimation d'un dessin imprimé sur une feuille de papier à un objet de forme quelconque.The present invention relates to a process for the sublimation transfer of a design printed on a sheet of paper to an object of any shape.

On connait des machines permettant la mise en oeuvre d'un procédé de ce genre et qui comprennent généralement, d'après la demande de brevet européen EP-A-0 252 610, une enceinte constituée d'un support rigide et d'un couvercle percé de trous, de façon à ne laisser dépasser une fois le couvercle fermé uniquement la face de l'objet à décorer. Ce dernier est posé sur le fond du support, tandis qu'une feuille de papier comportant un décor propre à se sublimer est mise en place sur le couvercle ainsi que sur la face à décorer.We know machines for implementing a process of this kind and which generally include, according to European patent application EP-A-0 252 610, an enclosure consisting of a rigid support and a cover pierced with holes, so as to leave only the face of the object to be decorated once the cover is closed. The latter is placed on the bottom of the support, while a sheet of paper with a decoration suitable for sublimating is placed on the cover as well as on the face to be decorated.

Une membrane synthétique déformable élastiquement recouvre le dessus de l'enceinte, ce qui permet lorsque cette dernière est mise sous vide de plaquer la feuille de papier à sublimer sur la face de l'objet.An elastically deformable synthetic membrane covers the top of the enclosure, which allows when the latter is placed under vacuum to press the sheet of paper to be sublimated on the face of the object.

L'ensemble, maintenu sous dépression, est introduit dans un four électrique pour réaliser la sublimation du dessin sur quelques millimètres de profondeur.The assembly, kept under vacuum, is introduced into an electric oven to sublimate the design over a few millimeters deep.

La méthode de décoration dite par sublimation employée couramment dans la technique antérieure n'est valable que pour des pièces de formes plates ou très légèrement bombées, car autrement la feuille de papier revêtue d'au moins une couche de matière à sublimer se plisse ce qui entraîne des défauts inadmissibles dans l'aspect de la décoration. De plus, les machines utilisées ne permettent pas la décoration d'un objet sur toutes ses faces.The decoration method known as sublimation commonly used in the prior art is only valid for pieces of flat shapes or very slightly curved, because otherwise the sheet of paper coated with at least one layer of material to be sublimated wrinkles which leads to unacceptable defects in the appearance of the decoration. In addition, the machines used do not allow the decoration of an object on all its faces.

Les perfectionnements qui font l'objet de l'invention permettent de remédier aux inconvénients énoncés ci-dessus et vise plus particulièrement un procédé pour la sublimation à chaud ou à froid d'un dessin sur toutes les faces d'un objet de forme quelconque, ainsi qu'une machine pour sa mise en oeuvre.The improvements which are the subject of the invention make it possible to remedy the drawbacks stated above and more particularly relates to a process for the hot or cold sublimation of a design on all the faces of an object of any shape, as well as a machine for its implementation.

Le procédé suivant l'invention se caractérise en ce qu'il consiste :

  • à coller une couche isolante sur la face opposée au décor à sublimer de la feuille-support de celui-ci ;
  • à placer la feuille-support de manière que la face recouverte de la couche isolante soit en contact avec la membrane inférieure de l'enceinte ;
  • à disposer au moins un objet de forme quelconque sur la feuille-support ;
  • à recouvrir l'objet d'une autre feuille-support de décor à sublimer de façon que sa face décorée soit en contact avec l'objet ;
  • à fermer hermétiquement l'enceinte au moyen d'une membrane supérieure imperméable élastique ;
  • à placer l'enceinte en dépression ;
  • et à introduire l'enceinte dans un four réglé à une température déterminé assurant le transfert du décor.
The process according to the invention is characterized in that it consists:
  • sticking an insulating layer on the face opposite the decoration to be sublimated from the support sheet thereof;
  • placing the support sheet so that the face covered with the insulating layer is in contact with the lower membrane of the enclosure;
  • placing at least one object of any shape on the support sheet;
  • covering the object with another decor support sheet to sublimate so that its decorated face is in contact with the object;
  • hermetically closing the enclosure by means of an elastic, impermeable upper membrane;
  • placing the enclosure under vacuum;
  • and to introduce the enclosure into an oven regulated at a determined temperature ensuring the transfer of the decoration.

En variante, le procédé suivant l'invention consiste :

  • à imprégner un tissu de solvant de la matière constitutive de l'objet ;
  • à placer le tissu sur la membrane inférieure de l'enceinte ;
  • à imbiber d'eau la feuille-support du décor à sublimer ;
  • à disposer la feuille-support de manière que sa face non imprimée soit en contact avec le tissu ;
  • à installer au moins un objet à décorer sur la feuillesupport ;
  • à recouvrir l'objet d'une autre feuille-support de décor à sublimer imbibée d'eau ;
  • à poser un autre tissu imbibé de solvant sur la feuillesupport ;
  • à fermer hermétiquement l'enceinte au moyen d'une membrane supérieure imperméable élastique ;
  • et à placer l'enceinte en dépression pendant le temps déterminé pour assurer le transfert du décor.
As a variant, the method according to the invention consists:
  • impregnating a fabric of solvent with the material constituting the object;
  • placing the fabric on the lower membrane of the enclosure;
  • soaking the backing sheet of the decor to be sublimated with water;
  • arranging the support sheet so that its unprinted side is in contact with the fabric;
  • installing at least one object to be decorated on the support sheet;
  • covering the object with another backing sheet of decor to sublimate soaked in water;
  • placing another cloth soaked in solvent on the backing sheet;
  • hermetically closing the enclosure by means of an upper membrane elastic raincoat;
  • and placing the enclosure under vacuum for the determined time to ensure the transfer of the decor.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 1 est une vue en perspective schématique d'une machine pour la mise en oeuvre du procédé suivant l'invention.Fig. 1 is a schematic perspective view of a machine for implementing the method according to the invention.

Fig. 2 et 3 illustrent la mise en place des objets et les différentes phases du procédé conforme à l'invention.Fig. 2 and 3 illustrate the placement of the objects and the different phases of the process according to the invention.

Fig. 4 illustre une variante du procédé de l'invention.Fig. 4 illustrates a variant of the process of the invention.

Fig. 5 représente schématiquement un four à bain d'huile pour la mise en oeuvre du procédé.Fig. 5 schematically shows an oil bath oven for implementing the method.

La machine représentée en fig. 1 comprend essentiellement deux cadres 1 et 2 de section carrée réalisés en aluminium et articulés entre eux de manière que l'un soit fixe et l'autre mobile.The machine shown in fig. 1 essentially comprises two frames 1 and 2 of square section made of aluminum and hinged together so that one is fixed and the other mobile.

Une membrane mince élastique 3, 4 étanche à l'air est collée ou assujettie de toute autre manière sur les faces inférieures des cadres 1 et 2. Les membranes considérées peuvent par exemple être réalisées en silicone acétique permettant de résister à de hautes températures et à de grandes déformations élastiques.A thin elastic membrane 3, 4 airtight is glued or otherwise fixed on the undersides of the frames 1 and 2. The membranes considered can for example be made of acetic silicone making it possible to withstand high temperatures and large elastic deformations.

Le dessus du cadre 1 est pourvu d'un joint d'étanchéité plat 5 réalisé en une matière équivalente aux membranes 3 et 4, de façon à constituer une liaison hermétique lorsque les deux cadres 1 et 2 sont pressés l'un contre l'autre au moyen de verrous 6 solidaires dudit cadre 1. Ces verrous peuvent être prévus sous la forme de fermetures de caisse de munitions coopérant avec des anses fixes 7 portées par le cadre 2.The top of the frame 1 is provided with a flat seal 5 made of a material equivalent to the membranes 3 and 4, so as to constitute a hermetic connection when the two frames 1 and 2 are pressed against each other. by means of locks 6 integral with said frame 1. These locks can be provided in the form of ammunition box closures cooperating with fixed handles 7 carried by the frame 2.

Les bords latéraux du cadre 1 sont traversés par des tuyaux 8 reliés à une pompe à vide 9, de manière que lesdits tuyaux débouchent dans une rainure 10 ménagée à l'intérieur du cadre 1 en vue d'assurer une meilleure répartition de la dépression sur toute la périphérie de l'enceinte fermée.The side edges of the frame 1 are crossed by pipes 8 connected to a vacuum pump 9, so that said pipes open into a groove 10 formed inside the frame 1 in order to ensure a better distribution of the depression over the entire periphery of the closed enclosure.

La première phase d'une première variante du procédé suivant l'invention consiste à coller une couche isolante telle que du papier d'aluminium 11 sur l'une des faces d'un support par exemple formé d'une feuille de papier 13 dont la face opposée est revêtue d'un décor 12 constituant une couche de matière propre à se sublimer. Cette phase n'est mise en oeuvre que dans le cas d'une sublimation à chaud afin d'éviter toute dispersion des couleurs du décor 12 vers l'extérieur.The first phase of a first variant of the method according to the invention consists in sticking an insulating layer such as aluminum foil 11 on one of the faces of a support for example formed from a sheet of paper 13, the opposite face is coated with a decoration 12 constituting a layer of material capable of sublimating. This phase is only implemented in the case of hot sublimation in order to avoid any dispersion of the colors of the decoration 12 towards the outside.

La seconde étape du procédé consiste à placer la feuille de papier 13 sur la membrane 3 de manière que le papier d'aluminium 11 soit en contact avec ladite membrane 3, comme illustré en fig. 2.The second step of the process consists in placing the sheet of paper 13 on the membrane 3 so that the aluminum foil 11 is in contact with said membrane 3, as illustrated in FIG. 2.

On dispose ensuite au moins un objet 14 de forme quelconque sur la feuille 13. Dans l'exemple représenté en fig. 2, on a disposé deux objets 14, 14′ l'un à côté de l'autre.There is then at least one object 14 of any shape on the sheet 13. In the example shown in FIG. 2, two objects 14, 14 ′ have been placed one next to the other.

On recouvre l'objet d'une autre feuille de papier 13′, de manière que son décor 12′ sublimable soit en contact avec ledit objet, tandis que le papier d'aluminium 11′ se trouve du côté de la membrane 4 du cadre 2.The object is covered with another sheet of paper 13 ′, so that its sublimable decoration 12 ′ is in contact with said object, while the aluminum foil 11 ′ is located on the side of the membrane 4 of the frame 2 .

On ferme le cadre 2 sur le cadre 1 au moyen de verrous 6-7 de façon à obtenir une liaison hermétique parfaite entre le joint plat 5 et la membrane 4.The frame 2 is closed on the frame 1 by means of latches 6-7 so as to obtain a perfect hermetic connection between the flat seal 5 and the membrane 4.

On met en route la pompe à vide 9 de manière à placer l'enceinte constituée des deux cadres 1 et 2 en dépression, si bien que les membranes 3 et 4 sont aspirées pour venir se plaquer énergiquement contre les feuilles de papier 13, 13′ dont les décors 12, 12′ sont appliqués contre toutes les surfaces périphériques de l'objet 14, 14′ (fig. 3).The vacuum pump 9 is started up so as to place the enclosure made up of the two frames 1 and 2 in vacuum, so that the membranes 3 and 4 are sucked up to come to press energetically against the sheets of paper 13, 13 ′ whose decorations 12, 12 ′ are applied against all the peripheral surfaces of the object 14, 14 ′ (fig. 3).

On introduit l'enceinte sous dépression dans un four électrique usuel comportant des résistances 15. Cette phase permet au décor 12, 12′ de chaque feuille 13, 13′ de se sublimer et de pénétrer de quelques millimètres sur la totalité de la surface de l'objet 14, 14′. Le temps de passage de l'enceinte dans le four est déterminé suivant la matière de l'objet 14, 14′ à décorer (fig. 3) afin de ne pas l'endommager.The vacuum chamber is introduced into a conventional electric oven comprising resistors 15. This phase allows the decoration 12, 12 ′ of each sheet 13, 13 ′ to sublimate and penetrate a few millimeters over the entire surface of the 'object 14, 14 ′. The passage time of the enclosure in the oven is determined according to the material of the object 14, 14 ′ to be decorated (fig. 3) so as not to damage it.

Lorsque la matière de l'objet 14, 14′ ne supporte pas des temps de passage trop long par risque de déformation, il est préférable d'introduire les cadres 1 et 2 de l'enceinte en dépression dans une poche 100 solidaire d'un cadre rigide 101 comme représenté en fig. 5.When the material of the object 14, 14 ′ does not withstand too long passage times by risk of deformation, it is preferable to introduce the frames 1 and 2 of the enclosure under vacuum in a pocket 100 secured to a rigid frame 101 as shown in fig. 5.

La poche 100 est réalisée en une matière semblable à celle des membranes 3 et 4 de l'enceinte, c'est-à-dire en silicone acétique de manière à résister à de hautes températures ainsi qu'à de grandes déformations. La poche 100 est ensuite plongée dans un four à bain d'huile 102 où l'huile 103 est maintenue à une température de 200° à 250° par l'intermédiaire de résistances 104. La poche 100 plongée dans le four 102 se déforme sous l'effet de la pression de l'huile 103 de manière à venir plaquer contre le pourtour extérieur des membranes 3 et 4 de l'enceinte. Cette déformation permet de transmettre immédiatement la température à la feuille 13, 13′ et à la surface de l'objet 14, 14′ en vue du transfert du décor 12, 12′ sur toute la surface de l'objet 14, 14′ . Ce transfert se réalise en quelques secondes permettant une reproduction parfaite du décor 12, 12′ sans entraîner une déformation de l'objet.The bag 100 is made of a material similar to that of the membranes 3 and 4 of the enclosure, that is to say made of acetic silicone so as to withstand high temperatures as well as large deformations. The pocket 100 is then immersed in an oil bath oven 102 where the oil 103 is maintained at a temperature of 200 ° to 250 ° by means of resistors 104. The pocket 100 immersed in the oven 102 is deformed under the effect of oil pressure 103 so as to press against the outer periphery of the membranes 3 and 4 of the enclosure. This deformation makes it possible to immediately transmit the temperature to the sheet 13, 13 ′ and to the surface of the object 14, 14 ′ with a view to transferring the decoration 12, 12 ′ over the entire surface of the object 14, 14 ′. This transfer takes place in a few seconds allowing a perfect reproduction of the decoration 12, 12 ′ without causing a deformation of the object.

La dernière opération consiste à ouvrir l'enceinte et à retirer la feuille en papier 13′ resté solidaire du papier d'aluminium 11′, le décor 12′ s'étant associé de manière indélibile à l'objet 14, 14′ sur une partie de sa périphérie.The last operation consists in opening the enclosure and in removing the paper sheet 13 ′ which remains secured to the aluminum foil 11 ′, the decoration 12 ′ having been associated indelibly with the object 14, 14 ′ on a part of its periphery.

Ensuite on retire l'objet 14, 14′ et la feuille de papier 13 restée solidaire de la feuille d'aluminium 11 dont le décor 12 s'est transféré à l'objet sur toutes ses parties non décorées par le décor supérieur 12′.Then the object 14, 14 ′ is removed and the sheet of paper 13 which remains integral with the aluminum sheet 11, the decoration 12 of which is transferred to the object on all of its parts not decorated by the upper decoration 12 ′.

En vue d'effectuer un transfert de décor sublimable sur des objets ne pouvant pas supporter une élévation de température suffisante pour l'application du procédé ci-dessus on réalise ce transfert à froid de la manière suivante :With a view to carrying out a sublimable decoration transfer on objects which cannot withstand a rise in temperature sufficient for the application of the above process, this cold transfer is carried out in the following manner:

Tout d'abord, le support du décor sublimable ou feuille de papier ne comporte pas la couche isolante consituée par la feuille d'aluminium 11, 11′First of all, the support of the sublimable decoration or sheet of paper does not include the insulating layer formed by the aluminum sheet 11, 11 ′

On place un tissu 16 imprégné de solvant sur la membrane 3 du cadre 1 de l'enceinte (fig. 4).A fabric 16 impregnated with solvent is placed on the membrane 3 of the frame 1 of the enclosure (fig. 4).

On imbibe d'eau la feuille en papier 17 et son décor 18.The paper sheet 17 and its decoration 18 are soaked with water.

On dispose la feuille en papier 17 de manière que sa face non imprimée soit en contact avec le tissu 16.The paper sheet 17 is placed so that its unprinted side is in contact with the fabric 16.

On installe au moins un objet 14, 14′ de forme quelconque sur la feuille en papier 17.At least one object 14, 14 ′ of any shape is installed on the paper sheet 17.

On recouvre l'objet 14, 14′ par une autre feuille en papier 17′, de manière que son décor 18′ soit en contact avec l'objet 14, 14′ .The object 14, 14 ′ is covered with another sheet of paper 17 ′, so that its decoration 18 ′ is in contact with the object 14, 14 ′.

On pose un autre tissu 16′ imprégné de solvant sur la feuille en papier 17′.Another fabric 16 ′ impregnated with solvent is placed on the paper sheet 17 ′.

On ferme le cadre 2 sur le cadre 1 au moyen des verrous 6-7, de façon à obtenir une liaison hermétique parfaite entre le joint plat 5 et la membrane 4.The frame 2 is closed on the frame 1 by means of latches 6-7, so as to obtain a perfect hermetic connection between the flat seal 5 and the membrane 4.

On met en route la pompe à vide 9 de manière à placer l'enceinte constituée des deux cadres 1 et 2 en dépression, si bien que les membranes 3 et 4 sont aspirées pour qu'elles plaquent énergiquement la feuille en papier 17, 17′ et son décor sublimable 18, 18′ contre toutes les surfaces périphériques de l'objet 14, 14′.The vacuum pump 9 is started up so as to place the enclosure made up of the two frames 1 and 2 in depression, so that the membranes 3 and 4 are sucked so that they forcefully press the paper sheet 17, 17 ′ and its sublimable decoration 18, 18 ′ against all the peripheral surfaces of the object 14, 14 ′.

Pendant la mise sous dépression de l'enceinte, le décor 18, 18′ est dilué par le solvant imprégnant le tissu 16, 16′ de telle sorte qu'il se transfère sur les parois périphériques de l'objet 14, 14′ . On note que le fait que les feuilles en papier 17, 17′ soient imbibées d'eau, retarde le transfert du solvant vers le décor 18, 18′ dont les motifs ne sont pas détruits par ce solvant qui n'entraîne que la sublimation des décors à l'objet.During the vacuuming of the enclosure, the decoration 18, 18 ′ is diluted by the solvent impregnating the fabric 16, 16 ′ so that it transfers to the peripheral walls of the object 14, 14 ′. It is noted that the fact that the paper sheets 17, 17 ′ are soaked in water, delays the transfer of the solvent to the decor 18, 18 ′ whose patterns are not destroyed by this solvent which only causes the sublimation of the decorations to the object.

La dernière opération consiste à ouvrir l'enceinte, à retirer le tissu 16, 16′, puis les feuilles de papier 17, 17′ les décors 18, 18′ étant associés de manière indélibile à l'objet 14, 14′ .The last operation consists in opening the enclosure, removing the fabric 16, 16 ′, then the sheets of paper 17, 17 ′ the decorations 18, 18 ′ being indelibly associated with the object 14, 14 ′.

On a ainsi réalisé un procédé de décoration soit à chaud, soit à froid, mais en utilisant la même machine pour sa mise en oeuvre.A decoration process was thus carried out either hot or cold, but using the same machine for its implementation.

Le procédé de décoration mis en oeuvre avec une telle machine permet de réaliser la décoration d'objets de formes quelconques, au besoin sur toutes leur périphérie.The decoration process implemented with such a machine allows the decoration of objects of any shape, if necessary on all their periphery.
