Abstract

The equipment for compressed air spraying of decorative coatings on walls consists of a compressor (1), turbofan (2) and tank (4) connected to a spraygun (3). The spray materials are stored in the multiple compartment tank (4). Individual valves for each compartment are fitted at the bottom of the tank. One or more sprayguns are connected to the valves with flexible hosing to a special connector (16) with as many inlets as there are tank compartments. Compressed air pressure is regulated by the turbofan or a push-button or screw control (18) connected to the spraygun. USE/ADVANTAGES - Improved design multiple choice of spray guns and spray material.

L'objet de l'invention se rattache notamment au 'secteur  The object of the invention relates in particular to the 'sector

technique de l'outillage des platriers-peintres et des maçons.  technique of tooling for plasterers and masons.

Les plafonds, murs et cloisons de locaux sont revêtus de produits divers tels que peintures, papier-peints, tissu mural, enduits, papiers fibreux On connait aussi les revêtements en pâte à papier ou autres produits comparables, projetés au pistolet à air comprimé à  The ceilings, walls and partitions of premises are coated with various products such as paints, wallpaper, wall fabric, coatings, fibrous papers.

La projection de pâte à papier avec ce type d'installation donne un effet décoratif intéressant, par la rugosité de la surface obtenue Cependant, lorsqu'on veut modifier la teinte naturelle de la pâte pour réaliser des coloris à la demande, il est nécessaire d'ajouter dans le réservoir un colorant et de faire des essais jusqu'à obtention de la teinte désirée Si l'on souhaite appliquer une autre teinte sur une25 surface voisine, il faudra nettoyer le réservoir avant de le remplir de pâte et d'y ajouter un autre colorant D'autre part, en réfection de surface, il sera difficile de retrouver la teinte d'origine On conçoit que ce genre d'installation limite les possibilités et nuit au rendement de telles opérations.30 C'est pourquoi, on a conçu l'installation selon l'invention qui permet de projeter à volonté soit une pâte à papier d'une seule couleur en alternance, soit plusieurs couleurs de pâtes à papier simultanément avec tout ce que cela implique comme effet décoratif35  The projection of paper pulp with this type of installation gives an interesting decorative effect, by the roughness of the surface obtained. However, when one wants to modify the natural shade of the pulp to achieve colors on demand, it is necessary to 'add a dye to the tank and experiment until the desired shade is obtained If you wish to apply another shade to a neighboring surface, you will need to clean the tank before filling it with paste and adding another colorant On the other hand, in surface repair, it will be difficult to find the original shade. It is understandable that this kind of installation limits the possibilities and harms the performance of such operations.30 This is why, we have designed the installation according to the invention which makes it possible to project at will either a paper pulp of a single color alternately, or several colors of paper pulp simultaneously with all that this implies as an effect decorative35

Pour cela, et selon une première caractéristique, l'installation qui comprend de manière connue un compresseur d'air et une turbine de ventilation, présente un réservoir de produit à projeter à plusieurs compartiments étanches entre eux reliés chacun, par l'intermédiaire d'une vanne, soit à un seul pistolet de projection soit à autant de pistolets, qu'il y a de compartiments, avec possibilité de réglage du  For this, and according to a first characteristic, the installation which comprises, in a known manner, an air compressor and a ventilation turbine, has a reservoir of product to be sprayed with several sealed compartments connected to each other, by means of a valve, either with a single spray gun or with as many guns, as there are compartments, with the possibility of adjusting the

On a voulu également multiplier les possibilité, les effets de projection des produits, et pour cela, selon une autre caractéristique, on prévoit de moduler la pression d'air à l'arrivée au pistolet parr un  We also wanted to multiply the possibilities, the projection effects of the products, and for this, according to another characteristic, we plan to modulate the air pressure on arrival with a spray gun by a

On a encore cherché à renforcer la couleur des paillettes projetées et à rendre aisément lavable la surface obtenue par adjonction dans la pâte d'additifs du type peinture acrylique ou vernis  We have also sought to reinforce the color of the projected flakes and to make the surface obtained easily washable by adding additives of the acrylic paint or varnish type to the paste.

selon un dosage approprié.according to an appropriate dosage.

Afin de retrouver facilement la teinte projetée, on a enfin prévu d'équiper chaque vanne de sortie du réservoir d'un moyen de repère tel que graduations qui, en relation avec la quantité définie de colorant introduit dans la pâte, correspond à une teinte répertoriée  In order to easily find the projected shade, provision has finally been made to equip each outlet valve of the reservoir with a reference means such as graduations which, in relation to the defined quantity of dye introduced into the paste, corresponds to a listed shade.

Comme illustré figure 7, le débit peut également être contrôlé et repéré par tous moyens tels que robinet gradué ( 15), afin de -4- retrouver aisément une teinte de pâte à papier par rapport à un  As illustrated in FIG. 7, the flow rate can also be controlled and identified by any means such as a graduated tap (15), in order to easily find a shade of paper pulp relative to a

En variante, comme on le voit en traits interrompus à la figure 2, il est prévu de raccorder les canalisations ( 5, 6, 7) chacune à un pistolet ( 3, 3 a, 3 b) afin de projeter en même temps plusieurs teintes de pâtes à papier, soit en tenant tous les pistolets dans  As a variant, as can be seen in broken lines in FIG. 2, provision is made to connect the pipes (5, 6, 7) each to a gun (3, 3 a, 3 b) in order to project several colors at the same time paper pulp, either by holding all of the guns in

une main, soit en manipulant deux pistolets à la fois.  one hand, or by handling two pistols at the same time.

La turbine ( 2) est reliée au pistolet ( 3) ou à chaque pistolet par une tuyauterie ( 17) et l'air pulsé peut être réglé en pression soit par action sur la turbine elle-même, soit par une dispositif du type boutonpoussoir ou vis ( 18) comme représenté à la figure 1, ou du type bague tournante ( 19) à ouverture ( 19 a) faisant communiquer ou non un orifice de mise à l'air libre ( 20 a) équipant un raccord ( 20) du  The turbine (2) is connected to the gun (3) or to each gun by a pipe (17) and the forced air can be regulated in pressure either by action on the turbine itself, or by a device of the push button type or screw (18) as shown in FIG. 1, or of the rotating ring (19) type with opening (19 a) communicating or not communicating an orifice for venting (20 a) equipping a connector (20) of the
