PROBLEM TO BE SOLVED: To simplify the constitution of an inclination regulating means of the axis of rotation of a pressure roller, to reduce the manufacturing cost, and to simplify the regulating work. SOLUTION: A pair of support shaft 32, 32 are arranged on a box 26 in a separate manner from each other in a direction opposite to seal rollers 22, 22 across a film feeding passage. An inclining means 42 to regulate the inclination of the support shaft 32 relative to the box 26 is arranged on each support shaft 32. A support cylinder 30 to support a rotary shaft 28 on which the seal roller 22 is mounted inside thereof is provided on holder 34 which is turnably and externally fitted to each support shaft 32 is provided through an arm part 30a. The inclination of the axis of rotation of the seal roller 22 is regulated by regulating the inclination of the support shaft 32 by the regulating means 42. |
