摘要： 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. The delivery means of the electrostatically charged painting powders, are placed at least at one or both of the doors of the said chamber (11), so that are continuously licked up by the depressurisation airflow of the same painting chamber, which prevents the deposit upon said means of powdered paint and which therefore maintains said means always perfectly clean.
