Summary:PROBLEM TO BE SOLVED: To provide an improved apparatus and method for extruding a seamless pipe composed of a thermoplastic no-derived cellulose solution. SOLUTION: A pipe composed of a thermoplastic solution comprising a non-derived cellulose, a tertiary amine oxide cellulose solvent and water is extruded from a circular die 14 through a clearance 24 down into an outer bath 20 of a non-solvent liquid to regenerate the cellulose from the solution and thereby a seamless pipe-shaped film 16 is extruded from the solution. The film is in the surrounding of a mandrel 26 equipped with an axis 28 and a sizing portion 30.
