PURPOSE: To increase the number of times of collecting operation by mounting cover cams on a can support body to be adjustable in a radius direction, and adjusting the cover cam by a cam part of an adjusting disc coaxial with the cam support body. CONSTITUTION: Cover cams 17 are mounted on a cam support body 22 to be radially adjustable. An adjusting disc 24 is disposed coaxially with the cam support body 22, and plural fixed circumferential cams 25 are provided. The cover cams 17 are disposed at deflected angles from each other, and the fixed circumferential cams 25 are also disposed at deflected angles from each other. Based on distribution angles of circumferential recesses in the cover cams 17, circumferential cams 25, and adjusting discs 24, a desired folding mode such as no collection, double collection, triple collection, etc., can be achieved, thereby increase of collection operation can be easily achieved. |
