The correlation (phase) relationship of the mounting angle with the paper tube 6 is that after the press units 27 on both sides have centered the paper tube W as “positioning units”, and at both ends of the paper tube W as “both-end processing units”. Before the formation of the curled portion R, as an operation of the fixing force increasing portion 28, the paper tube W is pressed against the paper tube holding portion 18 of the revolving transfer portion 3 by the pressing portion 52, and the pressing portions on both sides are formed. At the point after the curl portions R are formed at both ends of the paper tube W as the “both ends processing portion”, the fixing force increasing portion 2
As the operation 8, the timing is set so that the pressing of the paper tube W by the pressing portion 52 is released.

A spring 61 for urging the pressure lower part 52 downward is attached to the guide part 53, and the cam lever 57 is constantly driven by the second cam 5 by the spring force of the spring 61.
