APPARATUS FOR LEVELING FILM TUBE

摘要

PROBLEM TO BE SOLVED: To prevent obstruction generated by twisting and edge bending from being formed in a region of a leveled platen by driving rotatably a calibration device in the accurately same rotating direction as the rotating direction of the leveled platen in any case. SOLUTION: A calibration cage 15 (wherein a calibration ring, namely an annular segment 16 is held) is directly connected with a leveled platen 7 through a supporting piece 17 and it is constituted that the calibration cage 15 is turned reversely with the leveled platen 7 in the same direction and the same rotating angle. A servo motor is controlled by means of a controller in such a way that the calibration cage 15 is turned reversely in the same rotating direction as that for the leveled platen 7 and at a rotating angles being fittable to a distance of the calibration cage 15 from a film blow ink head 1 and the leveled platen 7. The calibration cage 15 provided with a supporting ring, namely the annular supporting segment 16 is fitted on a rotary ring provided with outer teeth through a carrier.
