The arm 2 is advanced so as to be sandwiched between the frame members 5 and 5 so that the elastic films 6 and 6 are brought into contact with the outer surface of the cylindrical molded body W and deformed along the outer surface of the cylindrical molded body W. , 0.
Since the cylindrical molded body W can be held so as to enclose the cylindrical molded body W with elasticity indicating a surface pressure of about 2 to 0.5 kg / cm 2 , the cylindrical molded body W is moved by moving the frame 7 of the cylinder 1. Can be taken out to any position.
Moreover, since it is possible to cope with the removal of the cylindrical molded bodies W of various sizes simply by replacing the elastic films 6, 6,
Switching time can also be shortened.
