Method and apparatus for producing a multi-layer laminate

摘要

A temperature-controllable roll 1 serves as a sealing tool, on the circumferential surface of which a number of plastic film tapes 14, 15, 16 are sealed to one another under pressure and application of heat. The plastic film tapes run at equal or different distances from one another onto the circumferential surface of the roll 1 and are led over pressure rolls 2, 3, ...7. These pressure rolls rest under pressure on the circumferential surface of the roll 1. The plastic film tapes run through the contact surfaces between the pressure rolls and the roll 1. The plastic film tapes are equipped on one or both sides with sealing layers, which are fused by the effect of heat, so that a sealing of the plastic film tapes arranged in layers one on top of the other occurs on the circumferential surface of the roll 1.
