Process for manufacturing a profiled layer stack

Disclosed is a method for manufacturing a profiled layer stack (1) by lamination. The stack of layers (1) has on one side a protruding layer (4) which forms a flap (5). When laminating the laminating plates are (15, 16) as a substitute for the region of the flap (5) non-existent layer material with inserts (6, 7) provided that provide a volume under and / or over the strap (5) the volume of the non-existent layer material corresponds. The inserts (6, 7) are constructed of a coated with non-stick material glass fabric (9). The laminating plates (15, 16) are provided with rough areas (19, 20) which in size and location on the inserts (15, 16) are matched.
