Problems solved by technology

[0013] Disadvantageously, apart from the technically limited distance between the hot and cold presses, due to the maximum future expected lamination lengths, feed distances occur, which occur on thermoplastics when producing small laminate structures. considerable losses, or the film structure has to be glued beforehand, separated into partial forms and placed at a defined distance on the release film

Embodiment Construction

[0071] figure 1 A multilayer thermoplastic film structure 1 in the form of a film strip is shown, which is formed from a thermoplastic film strip or from a plurality of sheet-like film structures arranged in the form of a film strip. The shown film structure 1 is composed, for example, of a 0.20 mm thick base film 1.1 of polycarbonate (PC) and of a cover film 1.2 of polycarbonate each having a thickness of 0.05 mm, arranged on both sides, Wherein, in an example, the cover film 1.2 has a width of 500 mm, and the base film 1.1 has a width of 550 mm, so that the index hole 2 mounted on the edge of the base film 1.1 is not covered by the cover film 1.2.

[0072] In the base film 1.1, the circuit is introduced into a grid of the same shape to produce a chip card or any other card-like product. In the example, five rows of card-sized, 85 mm long surface portions 4 are arranged transversely to the feed direction 3 at intervals of 10 mm. The surface portions 4 have a width of 55 mm ...

Abstract

The invention relates to a device (14) for laminating a film-tape-like multilayer thermoplastic film arrangement (1), according to the invention comprising heatable press plates (8.1, 8.2) and cooling surfaces (10), wherein the widths of said press plates (8.1, 8.2) and cooling surfaces (10) are greater than or equal to a width of the film arrangement (1), wherein the film arrangement (1) is arranged in the position thereof relative to the press plates (8.1, 8.2) in such a way that press plate edges (20) lie at the grid center (5.1) and the cooling surfaces (10) are arranged with a distance up to 3 mm next to a press plate edge (20) and beginning in the same grid (5), wherein a length of the cooling surfaces (10) is greater than or equal to a length of the press plates (8.1, 8.2) wherein one press plate (8.1, 8.2) and one cooling surface (10); are arranged on both sides of the film arrangement (1), wherein the press plates (8.1, 8.2) are fastened to press plate holding blocks (15) that can be moved or are supported by first press tables (19.1), and wherein the cooling surfaces (10) are part of cooling blocks (16) that can be moved or are supported by second press tables (19.2). The invention further relates to a multilayer thermoplastic laminated film arrangement (1) and to a method for laminating a film-tape-like multilayer thermoplastic film arrangement (1).

Description

technical field [0001] The invention relates to a device for laminating multilayer thermoplastic film structures in the form of film strips according to the features of the preamble of claim 1, a multi-layer thermoplastic film according to the features of the preamble of claim 9 Layer thermoplastic laminated film structures and a method for laminating multilayer thermoplastic film structures in the form of film strips according to the features of the preamble of claim 10 . Background technique [0002] The manufacture of smart cards, chip cards and electronic documents - the installation of antennas, electronic components, etc. Steps from two or more films followed by a first lamination to produce a pre-laminate forming a large-area thin laminate with multiple antennas, electronic components, etc. mounted in a special grid . [0003] Pre-laminates should essentially have the appearance and properties of a single-ply film. The better the quality of the pre-laminate, the be...
