Method and device for continuously producing composite strips or composite sheets

The invention relates to a method for producing composite webs or composite sheets, consisting of at least a first lower cover layer (1) of metal, a second upper cover layer (2) of metal, and a core layer (3) of plastic, which is arranged between the cover layers (1, 2) and is integrally bonded thereto, wherein a first metal strip (4) for the lower cover layer (1), a second metal strip (5) for theupper cover layer (2), and a plastic web (6) for the core layer (3) are brought together and are integrally bonded to each other by the application of pressure and/or heat. The method is characterized in that the first metal strip (4) and the second metal strip (5) are each continuously coated with an adhesion promoter in a pretreatment line (V) and then wound and that the first metal strip (4),the second metal strip (5), and the plastic web (6) are then brought together in a laminating line that is separate from the pretreatment line (L) and are continuously bonded to each other by the application of pressure and he
