The invention relates to a method for producing composite strips or composite sheets, consisting of at least a lower cover layer (1) of metal, an 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 the upper cover layer (2), and a plastic web (6) for the core layer (3) are continuously brought together and continuously integrally bonded to each other by the application of pressure and/or heat. The method is characterized in that the metal strips are locally bonded to each other by means of a strip-bonding device as the metal strips approach the continuous process.
In a method of making composite strips or sheets consisting of at least one first outer layer of metal, one second outer layer of metal, and at least one core layer of plastic between the outer layers and integrally joined therewith, where a first metal strip for the first outer layer, a second metal strip for the second outer layer, and a plastic web for the core layer are brought together continuously and integrally joined with one another continuously under the application of pressure and/or heat, the improvement wherein the metal strips are joined directly together locally by a strip-joining device during startup of the continuous process.
A system for making composite strips or sheets having at least one lower outer layer of metal, one upper outer layer of metal, and one core layer of plastic between the outer layers and integrally joined therewith, the system comprising;
