Title:
METHOD OF PRODUCING CAN BODY, CAN BODY, AND DEVICE FOR PRODUCING CAN BODY
Document Type and Number:
WIPO Patent Application WO/2006/046371
Kind Code:
A1
Abstract:
A method of producing a can body in which, when a barrel section of the can body is held between the outer peripheral surfaces of first and second rotation bodies (20, 21), the barrel section is pressed radially inward by a second projection (21a) from the outer periphery side of the barrel section such that at least a part of the quantity of deformation in the direction of the pressing is elastic deformation, the second projection (21a) is fitted into a first recess (20a) with the barrel section in between and with that portion of the inner periphery side of the barrel section which corresponds to the elastically deformed portion advanced into the first recess (20a), and after that, when the holding of the barrel section by the outer peripheral surfaces of the first and second rotation bodies (20, 21) is released, that portion of the barrel section that corresponds to the first recess (20a) and the second projection (21a) is caused to restore radially outward, thereby the outer peripheral surface of that portion of the barrel section which corresponds to the first projection (20b) is caused to position more outside than that outer peripheral surface of the barrel section which excludes the outer peripheral surface of that portion of the barrel section which corresponds to the first recess (20a) and the second projection (21a).
