Abstract

A method and a layout are described for coupling a polypropylene film A to a backing sheet B, in which there is a heated cylinder 3, co-operating with a counterpressure roller 4, between which are separately fed said film A and said backing sheet B, said cylinder 3 being thermostatically controlled at a temperature less than the melting point of the film A and being associated with at least one source 5 of infrared light, able to cause the melting of the surface of the film A intended to make contact with the corresponding surface of the backing sheet B. <IMAGE>
