Abstract: The machine for the horizontal painting with powdered paints, of three-dimensional and mainly flat wood products or its by-products, comprises a horizontal and motorised conveyor (1) upon which are resting the products to be painted which by suitable means are referred to an electric potential having a predetermined sign and which by the same conveyor are driven to pass through at least one chamber (11) connected to suction means which maintain the same in depression with respect to the external environment, because in said chamber are delivered by suitable means the powdered paints electrostatically charged with electric charges having an opposite sign to the one of the products, to strictly adhere to the same products. The whole is effected in such a manner that the particles of powder do not exit from the inlet and outlet mouths or doors of said chamber because of the suction effected by said suction means.

Abstract: At the interior of a working booth (1) of a painting machine with a robotized head (13), on the same guide (5) for the longitudinal and vertical movements of the said head, there is mounted a second ancillary painting head (19) similar to the one robotized, but constructively simplified in order to perform only oscillation movements for works of simple type. The ancillary spraying head is fixed at one extremity of the booth when the machine has to operate with the robotized head (13) upon panels stationary inside the same booth. Otherwise, when it has to operate upon travelling panels, the ancillary head (19) is moved to an intermediate and pre-established point of the same booth, while the robotized head (13) is placed and stopped at a distance from the ancillary head variable and correlated to the speed of travel of the panels and to the oscillating speed transversely to the same panels of both the heads, the guns of which are now actuated for performing works of simple painting.
