Claim Text:
1. A film-fitting device which sequentially delivers tubular films downstream while opening each tubular film by arranging the tubular film around a mandrel, and thereby causes the tubular film to be fitted around a body to be subjected to fitting that is transported to a position facing the mandrel, the film-fitting device comprising: a cutting mechanism that cuts a tube-forming medium into a predetermined length so as to form a tubular film having the predetermined length; a film transfer mechanism that transfers downstream the tubular film arranged around the mandrel; and at least one shot roller installed with its rotational shaft being slanted with respect to an axis core of the mandrel, the shot roller receiving the tubular film transferred by the film transfer mechanism, by causing the tubular film to be held between the shot roller and the mandrel, and delivering the tubular film downstream while rotating the tubular film in a circumferential direction, wherein a distance from the cutting mechanism to the shot roller and a distance from the film transfer mechanism to the shot roller are both greater than the length of the tubular film formed by the cutting; and rotational drive of the shot roller is carried out by an independent servo motor or stepping motor.
