Patent number: 6338263Abstract: A method for manufacturing an embossed can body with a pattern printed on an outer surface of a cylindrical can barrel includes a plastic working step for forming a flange portion and a neck portion at an opening peripheral edge of the can barrel, and an embossing step for forming an embossed portion on at least a part of the pattern while aligning with the pattern. Thus, the pattern and the embossed portion can be aligned easily and accurately. Also, a stopping mark and a confirmation mark are formed on the can barrel, and a first sensor corresponding to the stopping mark and a second sensor corresponding to the confirmation mark are used. When the respective first and second sensors detect the stopping mark and the confirmation mark, it can be confirmed that the pattern on the can barrel is oriented in a predetermined direction.Type: GrantFiled: June 22, 2000Date of Patent: January 15, 2002Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Kazumoto Obata, Wataru Ookubo, Sunao Morishita
