ABSTRACT:
A machine for bonding layers in a film includes first pay-off unit to unwind a first layer of the film, a second pay-off unit to unwind a second layer of the film, a third pay-off unit to unwind a third layer of the film, a bonding zone to join the various layers of film together, and a winding unit including a reel onto which the bonded film is wound, the bonding zone including at least one bonding unit, the pressing roller being fitted with at least an hydraulic actuator which brings it in contact with the layers of film on the bonding calender, the presser roller and the hydraulic actuator being mounted on a nip rotating around the axis of the bonding calendar so as to vary the position of the point of contact between the presser roller and the calender and hence to vary the breadth of the contact arc, along the surface of the calender, in which the layers are overlapped.
