If the pressing mechanism 111b is used, a certain pressing force can be obtained in all the pocket portions P, and a certain pressing force can be obtained irrespective of the amount of pressing depression of the plate 112, so that the adjustment is extremely easy and can be prevented from being operated. A change has occurred.

Further, in the case of using the pressing mechanism 111b, when the height of the can C is slightly reduced in the winding, even if the pressing mechanism 111b absorbs the upper and lower moving cams 123 of the above-described rolling head unit 120, the winding unit 130 moves up and down. The error of the cam motion trajectory of the cam 134 and the actual reduction of the height of the can, the axial load does not change, thereby improving the sealing accuracy and speeding up the processing.

Fig. 11 shows a can mounting unit 110c having a pressing mechanism of still another embodiment. As shown, the pressing mechanism 111c is configured to hold the piston 114c for lifting and lowering the plate 112c with respect to the cylinder space 113c by the diaphragm 118c. Confidentiality.

Thereby, the plate 112c can be smoothly moved up and down without the sealing resistance at the time of raising and lowering of the piston 114c.
