PURPOSE:To obtain a molded article that has uniform thcikness and is high in quality, by providing an apparatus for bearing an annular shaft via rotatable members. CONSTITUTION:Each apparatus 7 guides and bears, from outside, a coupling 47 at the connecting section of each of roll members 8, 8', 9, 9' rotatably provided at the center of an annular shaft 5. A ring 1 bears and rotates with the couplings 47, 47 for transmitting the output rotation of a motor to driving apparatuses 6, 6, for rotating the roll members 8, 8', 9, 9' about the annular shaft 5 and for rotating guide rollers 51, 51 of the apparatuses 7, 7, so that a film is take up from a circular die by the roll members 8, 8', 9, 9'. Thus, the present arrangement is economical and simple and can provide generally a molded article that has uniform thickness and is high in quality. |
