Problems solved by technology

[0007] The disadvantage of this is that the individual film / foil web segments have to be fed independently, which requires high equipment requirements and very high precision when carrying out the method
This is associated with high cost of equipment and various steps of the process may be slowed down

Embodiment Construction

[0067] figure 1 A schematic cross-sectional view of a first device according to the invention for producing laminates is shown. A first film / foil 1, a second film / foil 2, and a third film / foil 3 are fed to the device. The films / foils 1, 2, 3 are rolled onto and unwound from a drum 5 to be fed to the device.

[0068] The first film / foil 1 is prepunched and rolled onto a lower roll 5 . The first film / foil 1 and the second film / foil 2 are unwound and fed to the device. For this, the films / foils 1 , 2 are reoriented in a suitable manner such that they are guided parallel in a first region at a distance of about 5 mm. The first tool 6 of the device is arranged in the first region. The tool 6 comprises a heatable bottom surface 7 over which the first film / foil 1 is rolled over.

[0069] In this region of the tool 6 the second film / foil 2 is applied onto the first film / foil 1 and punched out in the process. The punched-out segment of the second film / foil 2 is then positioned on...

Abstract

A method for producing a laminate made up of at least two films / foils is provided. At least one first film / foil is structured and subsequently laminated to at least one second film / foil. The at least one second film / foil is punched by at least one tool in a single working step and is laminated to the structured first film / foil simultaneously. The films / foils are conveyed, at least part of the time, to the at least one tool. A laminate produced according to such a method and a device for producing a laminate using such a method are also provided. The device is suited for conveying and laminating the at least one first and second films / foils, wherein regions of the films / foils are aligned to be parallel with respect to each other. The device includes at least one tool that can be used to punch-laminate second film / foil onto the first film / foil.

Description

technical field [0001] The invention relates to a method for producing a laminate consisting of at least two films / foils, wherein at least one first film / foil is constructed and subsequently laminated to at least one on the second film / foil. [0002] The invention also relates to a laminate produced according to the method and a device for producing a laminate using the method. Background technique [0003] Laminates consisting of two films / foils have a wide range of applications in industry. In this context, for example, a metal foil is laminated to a plastic film or between two plastic films. In this process the film / foil is constructed such that the desired product is obtained. From WO 92 / 15118 it is known to apply two films / foil webs on top of each other in such a way that the stamped marks of one film / foil web and the stamped marks of the second film / foil web are arranged on the film / foil laminate at the same location. For this purpose, the position of the stampin...
