METHOD AND SYSTEM FOR PRODUCING COMPOSITE STRIPS OR COMPOSITE SHEETS

The invention relates to a method of making composite strips and composite sheets of at least one first outer layer (1) of metal, one second outer layer (2) of metal, and at least one core layer (3) of plastic between the outer layers (1, 2) and bonded unitarily thereto, a first metal strip (4) for the first outer layer (1), a second metal strip (5) for the second outer layer (2), and a plastic web (6) for the core layer (6) being laminated together and continuously bonded unitarily into a composite strip by application of pressure and/or heat, the first metal strip (4) and the second metal strip (5) being heated before the lamination and/or during the lamination, characterized by the fact that, after lamination and bonding of the metal strips (4, 5), an actual transverse curvature of the composite strips is measured, and that the temperature of the first metal strip (4) and/or of the second metal strip (5) is carried out before the lamination and/or during the lamination as a function of the actual transverse curvature. Furthermore, the invention relates to a system for carrying out the method with a transverse curvature sensor (15).
