Definitions

• the present invention relates to a tool for producing decorative patterns on plaster applied to a facade or to a floor.
• a coating layer is deposited on a surface to be coated.
• the coating can be applied directly, for example, to concrete or masonry, bricks, studs or stones.
• the deposition of this coating layer can be carried out by spraying by means of a machine or manually.
• the thickness of the plaster serves, on the outside, to provide on the one hand a decorative effect and on the other hand a waterproofing, while on the inside, it is mainly decorative.
• a layer of 10 to 15 millimeters of plaster can be applied.
• the coating can also be deposited on a smaller thickness in the case where waterproofing is not sought (example: the case of a concrete wall). Indeed, a coating thickness of the order of only 4 to 5 millimeters is necessary to achieve the decorative appearance according to the invention.
• the matrix may consist of a rigid or semi-rigid plastic sheet of small thickness and having a low weight per square meter.
• the matrix can be produced for example from a sheet of polystyrene. Other materials, such as polyurethane or polyethylene can be used.
• the decorative patterns can be produced by thermoforming or by stamping sheets or plastic rolls.
• the matrix can also consist of a sheet of plasticized cardboard. A very thin plastic film, such as, for example, a polyethylene film, is for example glued to the surfaces of a sheet of cardboard. The complex thus formed is then stamped to form the decorative patterns.
• the decorative patterns made on the plastic sheets can be multiple. These patterns can for example be geometric patterns and / or represent different types of imitation, imitations of wooden board representing the veining and the knots of different wood species as well as grooves between each board, imitation patterns of weaving, tiles, stones, paving, leaves, soil, etc.
• the matrix can also consist of a roller with relief. The desired patterns are then produced in relief on the surface of the roller held by a handle by the user.
• the roller is applied to the coating layer by interposing a plastic film, polyane type, in order to avoid the adhesion of the coating on the roller to produce the patterns by inlaying on the coated surface.
• a roller can be made of molded plastic.
• the polyane film of a few tenths of a millimeter can be pierced in order to extract the air between the coating layer and the film. The film is then removed as soon as the mastering operation is carried out.
• the present invention therefore aims to overcome the drawbacks of the prior art by providing a tool for producing decorative patterns on plaster which is easy to use by a single worker, which does not generate or tear the plaster or ripples.
• a tool for producing decorative patterns on plaster characterized in that it comprises a matrix formed or fixed on an endless stretched band, free to rotate and comprising at least one flat part constituting a bearing surface.
• the endless belt is stretched between at least two free rotating rollers.
• At least one roller is movable to adjust the tension of the endless belt.

• the endless belt (2) is made of a flexible material, for example rubber, latex or polyethylene.
• the matrix can be formed in the endless strip (2), for example by molding or thermoforming.
• This endless strip (2) is stretched by at least two rollers (6, 7) in contact with the inner face (21) of the endless strip (2), so as to form a flat part on its face (20). exterior.
• This flat part constitutes the bearing surface and is intended to be applied to the coating layer (3) so as to create the patterns (5).
• the decorative patterns (5) produced can be multiple. These patterns can for example be geometric patterns and / or represent different types of imitation, imitations of wooden board representing the veining and the knots of different wood species as well as grooves between each board, imitation patterns of weaving, tiles, stones, paving, leaves, of earth, etc.
• the endless strip (2) is stretched at each of its ends by a roller (6, 7), called the end roller.
• These two end rollers (6, 7) are similar and mounted to rotate freely between two bars (8, 9) or flanges.
• Two other rollers (10, 11) also mounted to rotate freely between the two bars (8, 9), called intermediate rollers, similar to the end rollers (6, 7), are aligned with the rollers (6, 7) end and interposed between the two end rollers (6, 7).
• the rollers (6, 7, 10, 11) are responsible for maintaining and guiding in rotation the flat part of the endless strip (2).
• the rollers (6, 7, 10, 11) have a length similar to the width of the endless strip (2).
• the rollers (6, 7, 10, 11) are fixed to the bars (8, 9), at each of their ends, by a screw (14).
• An end roller is for example free in translation (not shown in Figures 1 to 3) by its ends in elongated holes drilled in each bar (8, 9) parallel to the flat part of the endless strip (2) .
• the elongated shape of the holes allows the translation of the end roller relative to the other rollers, so as to adjust the tension of the endless belt (2). Once the tension of the endless belt (2) has been adjusted, the end roller is kept fixed in the elongated hole while still being free to rotate.
• the tool (1) is moved parallel to the facade or to the ground, the endless strip (2) being in contact with the coating (3), for example during setting, to cause the rotation of the strip (2 ) unending.
• a point X is chosen located on the endless belt (2), at the front end of the bearing surface of the endless belt (2), the direction of advance (A) of the roller being defined by the horizontal arrow in FIG. 3.
• This point X will remain fixed relative to the coating (3) for a distance d, corresponding to the length of the surface of support and substantially at the distance separating the axes of the two end rollers (6, 7).
• the point X will therefore remain in contact with the coating for a certain time depending on the value of this distance d and the speed of passage of the tool (1) according to the invention.
• each point of the matrix becomes point X at a given time. Any point of the matrix therefore remains in contact with the coating (3) for a given time depending on the length of the bearing surface and the speed of passage of the tool (1).
• This track principle used for the tool (1) according to the invention has the advantage of avoiding the tearing of the coating (3) and of avoiding the sticking of the coating (3) on the matrix, each point of the matrix remaining for some time in contact with the coating (3) before passing over the rollers.
• rollers (6, 7, 10, 11) will for example beveled (60) at each of their ends.
• the endless strip (2) folds inwards over the chamfered parts (60) of the rollers (6, 7, 10, 11). This makes it possible in particular to avoid marking the coating (3) when several adjacent passages of the matrix are made.
