ABSTRACT:
A method and an apparatus for welding halogen-free thermoplastic foils or plates, wherein one or more layers or inserts such as, e.g., reinforcement layers, are placed between the foils. The apparatus includes a welding tool which can be heated to the desired welding temperature and a countertool which can be adjusted to a temperature below the melting temperature of the foils. The countertool has a profile which corresponds to the desired welding or stamping contour, particularly a cutting edge. A heat-conducting separating foil can be placed in the welding apparatus for transmitting thermal energy produced by the welding tool and required for plasticizing the thermoplastic foils to the thermoplastic foils, wherein the foils can be separated from the separating foil after cooling. The method includes the steps of three-dimensionally pre-shaping at least one of the foils, so as to form an indentation and a foil support edge raised relative to the indentation. The lower foil is supported in the area of the foil support edge before or after insertion of the layer or layers in the indentation. Subsequently, the other foil is placed on the layer or layers and the support edge. The foils are lined or centered by means of a separating foil which extends in the region between the welding tool and the countertool in the form of a mask extending only along the support edge. Finally, the foils are welded in the support edge region with the intermediate arrangement of the separating foil between the welding foil and the thermoplastic foils.
