Abstract:
A manufacturing method for a thermoplastic resin laminated metallic sheet comprising the steps of:heating a continuously travelling metallic sheet,supplying two thermoplastic resin film having orientation to contact both surfaces of the metallic sheet moving in a traveling direction,pressing the metallic sheet and the thermoplastic resin films using a couple of laminating rolls by pinching them together to laminate them, and thereaftermoving a deflector roll, which is disposed downstream from the laminating rolls so as to contact one side thermoplastic resin film laminated on the metallic sheet and movable in a direction at a right angle from the traveling direction of the metallic sheet, to direct the laminated metallic sheet in a direction perpendicular to the traveling direction of the metallic sheet and to a direction opposite to an initial position of the deflector roll, so as to bias the traveling direction of the laminated metallic sheet with thermoplastic resin thereon to wind it round either one of the laminating rolls,wherein the two thermoplastic resin films have different melting temperatures.
