Title:
METHOD FOR MANUFACTURING EMBOSSED CAN BODY
Document Type and Number:
Japanese Patent JP3823952
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing an embossed can body which can manufacture a high-quality embossed can body in which the position of a pattern is coincident with the position of embossing by reducing a variation in shape of the can body and reliably positioning a pattern in embossing.
SOLUTION: A neck part and a flange part are formed on the periphery of an opening of a can body with a pattern printed on its cylindrical peripheral face. A positioning mark provided either on the pattern or separately from the pattern is then detected to conduct positioning of the can body. Thereafter, an inner roller is inserted into the can body, and an outer roller is disposed outside the can body. The outer roller is pressed against the can body, and the inner roller and the outer roller are rotated to emboss at least a part of the pattern to form a concave part and/or a convex part registered with the pattern.
