PROBLEM TO BE SOLVED: To achieve an excellent operationality, and enhance the durability of an extrusion laminating device. SOLUTION: The device includes an ozone supplying pipe 20 connected to an ozone supplying source and with a plurality of spraying holes 26 formed in the longitudinal direction, a width control pipe 28 being disposed surrounding the ozone supplying pipe 20 and for controlling a spraying width of ozone in a sliding manner, and seal means for supplying air between it and the ozone supplying pipe 20. Since ozone never leaks from the outside end part of the width controlling pipe 28, the extrusion laminating device does not suffer oxidation or breakage so that it can be enchanced in its durability. |
