Abstract

Method for masking certain parts of the surface of an object, so as to produce patterns on the said object by partially modifying the said surface, in particular by sandblasting. The said object (1) is covered with a mask (2) made from injection-moulded thermoplastic elastomer and which matches perfectly the contours of the said object (1), having openings (20) corresponding to those areas (11) on the surface (10) of the said object (1) which are intended to be made opaque.

Description

~d présente invention a pour objet un procédé de masquage de certaines parties de la surface d'un objet, afin de réaliser sur ledit objet des décors par altération partielle de ladite surface, altération par sablage notamment. ~ D of the present invention relates to a method of masking certain parts of the surface of an object, in order to produce on said object decorations by partial alteration of said surface, alteration by sandblasting in particular.

De tels décors sont réalisés sur des verres, flacons et objets de décoration, le sablage partiel de la surface faisant apparaître des dessins par alternance de zônes polies et dépolies. Such decorations are made on glasses, flasks and decorative objects, the partial sanding of the surface revealing designs by alternating polished and frosted areas.

Le procédé le plus couramment utilisé actuellement pour la réalisation de ces décors consiste à masquer la surface à épargner par application sur ladite surface d'un adhésif de forme ou résine, qui une fois le sablage effectué est enlevé. The most commonly used method currently for the production of these decorations consists in masking the surface to be saved by applying to said surface an adhesive of form or resin, which once the sanding has been carried out is removed.

Ce procédé présente de nombreux inconvénients, dont le principal est la difficulté d'application de l'adhésif donc la durée de l'opération, ce qui qui grève le coût de fabrication. De plus l'utilisation de ce procédé est très limité, car l'adhésif s'applique mal sur les formes complexes, et la localisation des espaces à épargner est difficule ce qui ne permet pas toujours d'obtenir un travail soigné. This process has many drawbacks, the main one being the difficulty in applying the adhesive and therefore the duration of the operation, which increases the manufacturing cost. In addition, the use of this process is very limited, since the adhesive is badly applied on complex shapes, and the location of the spaces to be saved is difficult, which does not always make it possible to obtain neat work.

D'autre part l'adhésif qui est détruit soit partiellement lors du sablage, soit complètement lors de son enlèvement, n'est pas réutilisable. On the other hand the adhesive which is destroyed either partially during sanding, or completely during its removal, is not reusable.

Enfin, ce procédé qui reste très artisanal, ne permet une réalisation industrielle de tel produit l'intervention manuelle étant trop importante, et la diffusion de ces produits reste très limitée du fait notamment du coût élevé de fabrication. Finally, this process, which remains very artisanal, does not allow industrial production of such a product, manual intervention being too large, and the distribution of these products remains very limited due in particular to the high manufacturing cost.

La présente invention permet de remédier à ces inconvénients en proposant un procédé de masquage de certaines parties de la surface d'un objet avant son sablage, permettant d'obtenir un résultat de qualité, propre et régulier quelque soit la complexité de forme dudit objet, tout en autorisant la possibilité d'une automatisation de fabrication très rapide, donc à un coût très réduit. The present invention overcomes these drawbacks by proposing a method of masking certain parts of the surface of an object before it is sanded, making it possible to obtain a quality, clean and regular result whatever the complexity of the shape of said object, while allowing the possibility of very rapid manufacturing automation, therefore at a very reduced cost.

Le procédé de masquage objet de la présente invention consiste dans un premier temps à réaliser une pièce en élastomère thermoplastique injecté, avantageusement en PVC ou en polyéthylène, épousant totalement ou partiellement l'objet à traiter. Cette pièce comporte des ouvertures tltifrespondant aux zônes à opacifier par sablage. Cette pièce peut alors être adaptée sur l'objet à traiter et l'ensemble est sablé. L'injection plastique étant une technique de grande précision, les contours des ouvertures sont précis ce qui permet d'obtenir un résultat propre et régulier. The masking process which is the subject of the present invention firstly consists in producing a part in injected thermoplastic elastomer, advantageously in PVC or in polyethylene, completely or partially matching the object to be treated. This part has openings corresponding to the areas to be opacified by sandblasting. This part can then be adapted to the object to be treated and the whole is sanded. Plastic injection being a technique of great precision, the contours of the openings are precise which allows to obtain a clean and regular result.

Après l'opération de sablage, la pièce ou cache peut être enlevée facilement du fait de la souplesse du matériau utilisé, ledit matériau étant également très résistant au sablage, le cache peut être réutilisé pour une pièce de même forme et dimensions. Selon le matériau utilisé et l'épaisseur de la paroi du cache, celui peut être utilisé environ un millier de fois avant qu'il soit nécessaire de le remplacer. After the sandblasting operation, the part or cover can be removed easily due to the flexibility of the material used, said material also being very resistant to sanding, the cover can be reused for a part of the same shape and dimensions. Depending on the material used and the thickness of the cover wall, it can be used about a thousand times before it needs to be replaced.

Il est ainsi aisé de réaliser une chaîne de fabrication, avec au départ un poste de pose des caches sur les objets à traiter, puis un poste de sablage, enfin un poste d'enlèvement des caches. It is thus easy to carry out a production line, initially with a station for placing the covers on the objects to be treated, then a sanding station, finally a station for removing the covers.

Le cache a un autre avantage, il permet de protéger l'objet à traiter pendant les différentes manipulations. The cache has another advantage, it protects the object to be treated during the various manipulations.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which relates to the appended drawing which represents a non-limiting embodiment thereof.

Dans le dessin annexé
- la figure 1 représente une vue en perspective d'un objet à traiter, un flacon, et de son cache avant la pose de celui-ci, cache réalisé selon l'invention.
In the attached drawing
- Figure 1 shows a perspective view of an object to be treated, a bottle, and its cover before the installation thereof, cover made according to the invention.

- la figure 2 représente une vue en perspective de l'objet à traiter. - Figure 2 shows a perspective view of the object to be treated.

Si on se réfère à la figure 1 on peut voir que l'objet 1 à traiter selon le procédé objet de la présente invention est un flacon présentant une surface 10 polie. Referring to FIG. 1, it can be seen that the object 1 to be treated according to the method object of the present invention is a bottle having a polished surface.

Avant le traitement, à savoir le sablage, un cache 2 réalisé en élastomère thermoplastique injecté, est placé étroitement sur le flacon 1. Ce cache 2 présente des ouvertures 20 qui peuvent être plus ou moins complexes représentant les dessins à réaliser sur le flacon par opacification. La précision de l'injection plastique permet de réaliser des dessins très complexes ce qui est actuellement limité par les procédés utilisés.  Before treatment, namely sanding, a cover 2 made of injected thermoplastic elastomer is placed tightly on the bottle 1. This cover 2 has openings 20 which can be more or less complex representing the drawings to be made on the bottle by opacification . The precision of the plastic injection makes it possible to produce very complex drawings which is currently limited by the methods used.

torque le cache 2 est adapté sur le flacon 1, l'ensemble est exposé au sablage dans un tunnel de sablage, et le sable va frapper la surface 10 du flacon 1 dans les ouvertures 20 pratiquées dans le cache 2. Puis le cache 2 est enlevé, et le résultat obtenu est celui, si on se réfère à la figure 2, d'un flacon 1 dont la surface 10 polie présente des zones 11 dépolies correspondant aux ouvertures 20 du cache 2.  torque the cover 2 is fitted on the bottle 1, the assembly is exposed to sandblasting in a sandblasting tunnel, and the sand will strike the surface 10 of the bottle 1 in the openings 20 made in the cover 2. Then the cover 2 is removed, and the result obtained is that, if one refers to FIG. 2, of a bottle 1, the polished surface 10 of which has frosted zones 11 corresponding to the openings 20 of the cover 2.
