Laminating machine for producing multilayer films

A laminating machine for producing multilayer films, comprising:

• at least one first unwinding assembly, configured to take a first film from a first spool;
• at least one second unwinding assembly, configured to take a second film from a second spool;
• at least one third unwinding assembly, configured to take a third film from a third spool;
• at least one first laminating unit and at least one second laminating unit configured to laminate together said first film, said second film and said third film, with the interposition of an adhesive material, in order to obtain a multilayer laminated film wherein said at least one first laminating unit and at least one second laminating unit are arranged in mutual succession, said first laminating unit being configured to laminate together two films from said first film, said second film, and said third film, said second laminating unit being configured to laminate a remaining film that is not yet laminated with the laminated film that was obtained in said first laminating unit;
• at least one first applicator assembly and at least one second applicator assembly of said adhesive material, which are arranged upstream of said at least one first laminating unit and at least one second laminating unit;
• at least one winding assembly for said multilayer laminated film, which is arranged downstream of said at least one first laminating unit and at least one second laminating unit;
• said first unwinding assembly and said second unwinding assembly being arranged along a first direction of extension of the machine,
• wherein said third unwinding assembly is arranged along a second direction of extension of the machine which is substantially transverse with respect to said first direction of extension, said third unwinding assembly being positioned laterally with respect to a vertical plane of the machine which is substantially parallel to said first direction of extension and passes through said first unwinding assembly and said second unwinding assembly;
• and wherein said at least one first applicator assembly is arranged between said first unwinding assembly and said first laminating unit and configured to apply at least a first adhesive layer to the face of said first film that is intended to be laminated with said third film, and at least one second applicator assembly, arranged between said second unwinding assembly and said second laminating unit and configured to apply at least one second adhesive layer to the face of said second film that is intended to be laminated with the two-layer laminated film that exits from said first laminating unit;
• a redirection element for said third film, between said third unwinding assembly and said at least one first laminating unit and at least one second laminating unit which is configured to redirect the advancement path of said third film along a direction having at least one component that is substantially parallel to said first direction of extension
• a plurality of first advancement rollers, configured to convey said first film from said first unwinding assembly to said at least one first laminating unit and at least one second laminating unit along at least one first advancement path, which has at least one component substantially parallel to said first direction of extension;
• a plurality of second advancement rollers, configured to convey said second film from said second unwinding assembly to said at least one first laminating unit and at least one second laminating unit along at least one second advancement path, which has at least one component substantially parallel to said first direction of extension, and along an advancement direction that is opposite to the advancement direction of said first film along said first advancement path;
• and
• a plurality of third advancement rollers, configured to convey said third film from said third unwinding assembly to said redirection element along a third advancement path, which has at least one component substantially perpendicular to said first direction of extension.
