ップ隣接側縁の正確な突き合わせは不要である。As described above, in the present invention, the joining of the adjacent winding side edges of the liner-constituting strip 1 is performed by using the strip 1
One element of the joint 2 formed by a tenon strip 21 and a tenon slot groove 22 protruding outward from the side edge of the strip 1 and extending in the length direction of the side edge, and one element of the joint 2 is connected to one side edge of the strip 1. The strip 1 is formed on the other side edge, and these elements are fitted. According to this, the pressing of the strip required for joining the strip side edge only needs to be applied to one direction side, that is, the preceding winding side of the strip, and the joining of the strip side edge can be easily achieved, and as in the conventional case. Accurate butting of the adjacent strip edges is not required.
