发明名称 Device and process for producing a multi-layer film composite
摘要 A device and method of producing a multi-layer film composite is provided. In accordance with the device and method, a temperature-controllable or heatable 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 are in contact with the circumferential surface of the heatable roll under pressure. The plastic film webs pass through the gaps between the pressure rolls and the heatable roll. The plastic film webs are alternately sealing layer-free or provided on one or both sides with sealing layers, which are fused by the action of heat, so that sealing of the laminated plastic film webs on the circumferential surface of the heatable roll occurs.
