[0021] In order to facilitate taking away the coiled material on the winding roller 1, in this embodiment, the winding roller 1 is an air-expanding roller.

[0022] In this embodiment, the transmission portion 12 and the clamping portion 13 on the winding roller shaft 1 are distributed in a stepped shaft shape.
