The invention concerns a method for the production of a flat composite (5) from plastic parts by means of a thermal adhesion of two plastic parts (1,1'), heated on one side of their surfaces (1a,1a'), consisting of plastics A and B, wherein the surfaces (1a,1a') are heated on the adhesive side to surface temperatures of 10 to 100 K above the Vicat softening points VET (according to DIN ISO 306) of the pertinent plastics A and B, provided that the plastic parts (1,1') retain their original shape during the preheating phase, and are pressed between a pair of rolls (2,3), at an advance rate between 5 and 200 mm/sec and with a pressing force between 10 and 500 N acting on the roll (3); preferably, the plastics (1,1') exhibit engraving or embossing (6,6'), with which composite (5) can be produced with a three- dimensional inclusion (7) of a defined shape; furthermore, a flat or elongated object (8) is embedded between the plastic parts (1,1') to be adhered during the adhesion of the composite (5).
