PROBLEM TO BE SOLVED: To provide a film fitting head allowing secured performance of fitting operation of a cylindrical film to a pot part having an outer shape of an irregular shape excluding a circular shape.SOLUTION: A film fitting head includes: a mandrel shaft 84 having a tapered tip; a film dispensing guide 86 vertically moving by driving first cam mechanisms 76 and 94, to a film receiving position where each upper end part 86a retreats below a tip 84a of the mandrel shaft 84, and a film dispensing position where each of the upper end parts 86a is projected to the periphery of a tip 84a of the mandrel shaft so as to dispense in a state of opening a cylindrical film of a dimension almost equal to that of the peripheral shape of a pot part of a container C; and a push-up plate 88 moving upward by driving second cam mechanisms 78 and 96 when the film dispensing guide 86 is in the film dispensing position, and pushing up the cylindrical film fitted to the mandrel shaft 84 along the film dispensing guide 86.SELECTED DRAWING: Figure 13 |
