Industrial machine for applying temporary or permanent protective films to planar surfaces acting simultaneously on two faces, having a system for cutting the film and positioning edge-to-edge or with a margin, automatically adapting to suit changes in the parts that are to be treated, using an electrostatic method

An industrial machine for vertically applying temporary or permanent protective films on plane surfaces and having an automatic system for cutting the film, positioning it edge-to-edge or with a margin acting simultaneously on both faces and adapting automatically to changes in the format of the parts for treatment, using an electrostatic charge method for positioning and holding the film in position on the applicator roller, the machine being characterized by:

• An overall assembly (FIG. 1) also referred to as a “stand”, provided with a system for conveying and positioning the product for protecting;
• Two film-coating modules (r and s) (FIGS. 2 and 3) placed on linear guides of the structure for moving them vertically and horizontally, one film-coating module for coating the front face of the product, the other film-coating module for coating the rear face of the same product;
• A controller having a program for controlling the various modules of the machine as a function of the dimensions of the media for treatment.
