摘要： A system for producing a multiple layer material (49), comprising first and second corrugation rolls (14, 15) for providing a corrugated profile (16) having a plurality of crests (47), wherein the system further comprises first and second press rolls (21, 22) for applying a material sheet (19, 20) to crests (47) of the corrugated profile (16), and a plurality of heating members (28) arranged between the press rolls (21, 22) for welding the material sheet (19, 20) to the crests (47) of the corrugated profile (16) to form the multiple layer material (49). A guiding plate (48) is arranged between the corrugation 10 rolls (14, 15) and the heating members (28). The guiding plate (16) is arranged with a profile engaging side (50) having a plurality of crests (52) corresponding to the crests (47) of the corrugated profile (16). A cooling arrangement is provided for cooling the guiding plate (48). A method for producing the multiple layer material (49) is also disclosed.
