A device and process useful for producing a plurality of individual film composites is disclosed. A temperature-controllable roll serves as a sealing tool, on the circumferential surface of which a number of plastic film webs are sealed together under the application of pressure and heat. The plastic film webs come into contact with the circumferential surface of the roll at equal or varying distances from each other and are guided over pressure rolls. These pressure rolls contact the circumferential surface of the temperature controllable roll under pressure. The plastic film webs pass through the contact areas between the pressure rolls and the temperature controllable roll. The plastic film webs are provided on one or both sides with sealing layers, which are fused by the action of heat, so that sealing of the superposed laminated plastic film webs on the circumferential surface of the temperature controllable roll occurs. No sealing layers are present at least between two superposed plastic film webs, so that the film composite can be separated at the sealing layer-free surfaces of these plastic film webs into individual composites along a partial circumference of a separating roll.
