<p>This invention relates to a machine for bonding up to three films (S1,S2,S3), possibly made of different materials, characterised in that it comprises:
€¢ a first unit (2) designed to pay out a first film (S1) associated with a spreader/applicator unit (4) to apply a layer of adhesive to one surface of said film (S1).
€¢ a second unit (3) designed to pay out a second film (S2) associated with a spreader/applicator unit (5) to apply a layer of adhesive to one surface of said film.
€¢ a third unit designed to pay out a third film (S3).
€¢ a fourth unit comprising two bonding machines (1) designed to join the various layers of film together. Said bonding units (1) comprise a bonding calender, onto which the various layers of film are wound, and at least one presser roller which is subject to the action of hydraulic actuators, the two bonding units being positioned between the two pay-out/applicator units.</p> |
