ABSTRACT:
The invention relates to a machine for applying film.
The machine comprises a winding arrangement on which the roll of film is stored, a station for glueing the film, a tunnel oven followed by an applicator unit composed of a pressure roller and a counter-pressure roller between which passes the glued film and the cardboard supports comprising cut-outs in order to press the film onto the front side of the cardboard supports.
According to the invention, the arrangement of the cardboard supports covered with film is deflected at the outlet of the applicator unit, in order to separate the arrangement from the counter-pressure roller.
The invention will be used in particular for applying film to cardboard supports comprising cut-outs, serving to form packaging boxes provided with a transparent window.
