La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer Figures 1 et 2 sont des vues montrant un support d'encre qui est recouvert d'une couche isolante constituée de polyvinyle d'alcool (PVA).- to remove the object on which the decor of the oven is transferred. The description which follows with reference to the appended drawings, given by way of nonlimiting examples, will make it possible to better understand the invention, the characteristics which it presents and the advantages which it is capable of providing. FIGS. 1 and 2 are views showing an ink support which is covered with an insulating layer made of polyvinyl alcohol (PVA).
Figures 3 et 4 sont des vues illustrant un support d'encre qui est recouvert d'une couche isolante constituée de paraffine ou analogue. on a représente en figure 1 et 2 un support d'encre 1 qui comprend un élément 10 qui est réalisé en un matériau extensible perméable à l'air tel qu'un tissu, un tricot, ou une feuille de matière non tissé. L'élément 0 est recouvert sur l'une de ses faces d'une couche isolante 11 qui peut être du polyvinyle d'alcool (PVA) ou analogue. La couche isolante 11 est déposée sous forme liquide afin que l'élément 10 soit parfaitement imprégné.Figures 3 and 4 are views illustrating an ink carrier which is covered with an insulating layer consisting of paraffin or the like. FIG. 1 and 2 show an ink support 1 which comprises an element 10 which is made of an extensible material permeable to air such as a fabric, a knitted fabric, or a sheet of nonwoven material. The element 0 is covered on one of its faces with an insulating layer 11 which may be polyvinyl alcohol (PVA) or the like. The insulating layer 11 is deposited in liquid form so that the element 10 is perfectly impregnated.
La couche isolante 11 réalisé en polyvinyle d'alcool (PVA) à pour caractéristique principale de durcir lors de son séchage permettant de rendre l'élément 10 stable et rigide.The main insulating layer 11 made of polyvinyl alcohol (PVA) hardens during drying, making the element 10 stable and rigid.
Dès que l'élément 10 est stabilisé et rigide, la couche isolante 11 est recouverte d'une pellicule d'encre sublimable 12 qui est déposée par une impression de type jet d'encre ou par tout autre système d'impression.As soon as the element 10 is stabilized and rigid, the insulating layer 11 is covered with a sublimable ink film 12 which is deposited by an ink jet type printing or by any other printing system.
La pellicule d'encre sublimable 12 comprend un décor qui sera transféré sur toute la surface d'un objet à décorer comme on le verra mieux plus loin. Le support d'encre 1 permet la décoration d'objet de forme quelconque par transfert ou migration des encres sublimables de la pellicule 12 dans la surface de l'objet.The sublimable ink film 12 includes a decoration which will be transferred over the entire surface of an object to be decorated as will be seen better below. The ink support 1 allows the decoration of any object of any shape by transfer or migration of the sublimable inks of the film 12 in the surface of the object.
Pour cela, on humidifie l'élément 10 avec de l'eau pour ramollir la couche isolante 11 et plus particulièrement le polyvinyle d'alcool afin que ledit support retrouve son élasticité dans toutes les directions.For this, the element 10 is moistened with water to soften the insulating layer 11 and more particularly the polyvinyl alcohol so that said support regains its elasticity in all directions.
On enveloppe l'objet dans le support d'encre 1 afin que toutes ses faces soient en contact avec la pellicule d'encre sublimable 12. On place l'objet envelopper dans le support d'encre 1 dans une machine sous vide, connue en soi, pour plaquer le support d'encre contre les faces de l'objet.The object is wrapped in the ink support 1 so that all of its faces are in contact with the sublimable ink film 12. The object wrapped is placed in the ink support 1 in a vacuum machine, known in itself, to press the ink support against the faces of the object.
On chauffe à une température inférieure à 80° degrés pour durcir l'élément 10 autour de l'objet par όvaporation de l'eau contenu dans la couche isolante 11 constituée de polyvinyle alcool. On chauffe le support d'encre 1 et l'objet pendant quelques minutes afin que ledit support se durcisse à la forme de l'objet.Heated to a temperature below 80 ° degrees to harden the element 10 around the object by evaporation of the water contained in the insulating layer 11 made of polyvinyl alcohol. The ink support 1 and the object are heated for a few minutes so that said support hardens to the shape of the object.
On retire de la machine sous vide l'objet et le support d'encre 1. On place quelques secondes l'objet enveloppé du support d'encre 1 dans un four, préalablement chauffer à une température élevée, comprise entre 200° et 1000° degrés, pour permettre le transfert du décor de la pellicule d'encre sublimable 12 sur toute la surface dudit objet.The object and the ink carrier 1 are removed from the vacuum machine. The object wrapped in the ink carrier 1 is placed for a few seconds in an oven, previously heated to a high temperature, between 200 ° and 1000 °. degrees, to allow the transfer of the decoration of the sublimable ink film 12 over the entire surface of said object.
La température du four varie en fonction de la matière de l'objet à décorer.The oven temperature varies depending on the material of the object to be decorated.
En outre la température élevée du four permet une migration immédiate des encres subiimables de la pellicule 12 sur la surface de l'objet sans risque de détérioration dudit objet. On retire le support d'encre 1 pour pouvoir récupérer l'objet sur lequel est transférer le décor.In addition, the high temperature of the oven allows immediate migration of the subjectable inks of the film 12 on the surface of the object without risk of deterioration of said object. The ink support 1 is removed in order to be able to recover the object onto which the decoration is transferred.
On a montré en figures 3 et 4 un autre support d'encre 2 qui comprend un élément 20 qui est réalisé en un matériau extensible perméable à l'air tel qu'un tissu, un tricot, ou une feuille de matière non tissé.Another ink support 2 has been shown in FIGS. 3 and 4 which comprises an element 20 which is made of an extensible breathable material such as a fabric, a knitted fabric, or a sheet of nonwoven material.
L'élément 20 est imprégné sur l'une de ses faces d'une couche isolante 21 qui est constituée de silicone ou de paraffine. La couche isolante 21 est recouverte d'une pellicule d'encre sublimable 22 identique à celle 12 décrite précédemment.The element 20 is impregnated on one of its faces with an insulating layer 21 which is made of silicone or paraffin. The insulating layer 21 is covered with a sublimable ink film 22 identical to that 12 described above.
La pellicule d'encre sublimable 22 comprend un décor qui sera transféré sur toute la surface d'un objet à décorer comme on le verra mieux plus loin.The sublimable ink film 22 includes a decoration which will be transferred over the entire surface of an object to be decorated as will be seen better below.
Une couche adhésive 23 est prévue sur toute la surface du support d'encre 20 de manière à recouvrir la pellicule d'encre sublimable 22.An adhesive layer 23 is provided over the entire surface of the ink support 20 so as to cover the film of sublimable ink 22.
On constate que la pellicule d'encre sublimable 22 est isolée de l'extérieur du support d'encre 2, car elle est prise en sandwich entre la couche isolante 21 et la couche adhésive 23.It can be seen that the sublimable ink film 22 is isolated from the outside of the ink support 2, since it is sandwiched between the insulating layer 21 and the adhesive layer 23.
Le support d'encre 2 permet la décoration d'objet de forme quelconque par transfert ou migration des encres subiimables de la pellicule 22 dans la surface de l'objet.The ink support 2 allows the decoration of any object of any shape by transfer or migration of the submissible inks from the film 22 in the surface of the object.
Pour cela, on enveloppe l'objet dans le support d'encre 2 afin que toutes ses faces soient en contact avec la couche adhésive 23.To do this, the object is wrapped in the ink support 2 so that all of its faces are in contact with the adhesive layer 23.
On place l'objet envelopper dans le support d'encre 2 dans une machine sous vide, connue en soi, pour plaquer le support d'encre et coller à froid la couche adhésive 23 contre les faces de l'objet.The wrapped object is placed in the ink support 2 in a vacuum machine, known per se, to press the ink support and cold glue the adhesive layer 23 against the faces of the object.
On retire de la machine sous vide l'objet enveloppé du support d'encre 2.The object wrapped in the ink support 2 is removed from the vacuum machine.
On enlève le support d'encre 2 de manière que la couche adhésive 23 retienne la pellicule d'encre sublimable 22, représentant le décor à transférer, sur toutes les faces de l'objet à décorer. L'objet est complètement recouvert sur toute sa surface de la pellicule 22 comprenant le décor à transférer. L'application à froid de la pellicule d'encre sublimable 22 sur la surface de l'objet a été possible puisque cette dernière est isolée de l'élément 20 par la couche isolante 21. On place l'objet, sur lequel est collé la pellicule d'encre sublimable 22 au moyen de la couche adhésive 23, dans un four préalablement chauffer à une température élevée, comprise entre 200° et 1000° degrés, pour permettre le transfert des encres sur toute la surface dudit objet.The ink support 2 is removed so that the adhesive layer 23 retains the sublimable ink film 22, representing the decoration to be transferred, on all the faces of the object to be decorated. The object is completely covered over its entire surface with the film 22 comprising the decoration to be transferred. The cold application of the sublimable ink film 22 on the surface of the object was possible since the latter is isolated from the element 20 by the insulating layer 21. The object is placed on which the sublimable ink film 22 by means of the adhesive layer 23, in an oven previously heated to a temperature high, between 200 ° and 1000 ° degrees, to allow the transfer of inks over the entire surface of said object.
Le temps de passage de l'objet est très court pour que ce dernier ne puisse pas se déformer et se détériorer sous l'effet de la chaleur. En outre la migration des encres sublimable dans la surface de l'objet est réalisé par la volatilisation de la couche adhésive 23 sous l'effet de la chaleur.The passage time of the object is very short so that it cannot deform and deteriorate under the effect of heat. In addition, the migration of sublimable inks into the surface of the object is achieved by the volatilization of the adhesive layer 23 under the effect of heat.
On retire l'objet sur lequel est transféré le décor du four.We remove the object on which the decor is transferred from the oven.
Ainsi, lorsque l'objet comporte des formes courbes ou sphériques, le support d'encre 1 , 2 s'allonge dans toutes ses directions de manière à envelopper parfaitement la surface de l'objet. L'application du support d'encre 1 , 2 sur l'objet à décorer est réalisée au moyen de la machine à sublimer décrite dans le brevet Européen 0451065.Thus, when the object has curved or spherical shapes, the ink support 1, 2 elongates in all its directions so as to perfectly envelop the surface of the object. The application of the ink support 1, 2 on the object to be decorated is carried out by means of the sublimating machine described in European patent 0451065.
Cette machine permet lorsqu'elle est mise sous vide de plaquer le support d'encre 1 , 2 sans pli et sans froissement sur toute la surface de l'objet à décorer. This machine makes it possible, when it is put under vacuum, to press the ink support 1, 2 without creases and without wrinkling on the entire surface of the object to be decorated.
