Multilayer thermoplastic laminated film arrangement and device and method for laminating

摘要

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 a width of said press plates (8.1, 8.2) and cooling surfaces (10) is 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) such 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 respectively 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 multi-layer thermoplastic laminated film arrangement (1) and to a method for laminating a film-tape-like multilayer thermoplastic film arrangement (1).

主权项

1. A device for laminating a film-tape-like multilayer thermoplastic film arrangement having a width and which is formed from a thermoplastic film-tape or from a plurality of sheet-like film arrangements consecutively arranged in the manner of a film-tape, wherein the film arrangement has surface portions divided into uniform lattice steps at least in the feed direction, said surface portions being separated by means of grids having a grid center, and wherein the lamination takes place under the application of pressure and heating of a laminating section of the film arrangement up to a temperature in the softening region of the thermoplastic and subsequent cooling of the heated laminating section under pressure, said device comprising:
heatable press plates; and cooling surfaces, wherein a width of said press plates and cooling surfaces is greater than or equal to the width of the film arrangement, wherein the press plates and cooling surfaces are positioned to receive the film arrangement such that press plate edges lie at the grid center and the cooling surfaces are a distance up to 3 mm next to a press plate edge and beginning in the same grid (5), wherein a length of the cooling surfaces is greater than or equal to a length of the press plates, wherein one press plate and one cooling surface are on both sides of the film arrangement; press plate holding blocks, wherein the press plates are fastened to the press plate holding blocks that can be moved or are supported by first press tables; and cooling blocks, wherein the cooling surfaces are part of the cooling blocks that can be moved or are supported by second press tables.
