By the way, since the thin-walled tubular body (a) itself is poor in rigidity, it is not easy to automatically take out the thin-walled tubular body (a) covering the mandrel from the mandrel, and this is a great way to automate this kind of work. It is an obstacle. The above-mentioned prior arts all attempt to make this possible.
There were drawbacks such as lack of certainty and complicated structure.

For example, in the technique of Japanese Patent Laid-Open No. 59-98818, the thin-walled tubular body (a) is removed from the mandrel by pressing a roller against the thin-walled tubular body (a) covered by the mandrel and driving the roller. Therefore, the problem of slip still remains, and there is a drawback that the certainty is poor.
Further, in this case, since the thin cylindrical body (a) is simply taken out from the mandrel by the roller, it is difficult to smoothly guide it to the article (B). The situation that it is not possible occurs.

On the other hand, in the technique of Japanese Patent Publication No. 53-5159, compressed air is sent between the outer surface of the mandrel and the inner surface of the thin-walled tubular body (a) covering the mandrel to expand the tip of the thin-walled tubular body (a). Since the thin-walled cylindrical body (a) is taken out from the mandrel by pushing this with a push ring while diametrically, there are few drawbacks as in the case of JP-A-59-98818. Since it has to be arranged so as to slide in the axial direction of the mandrel, there is a drawback that the structure becomes complicated.
