Abstract (en)
A production apparatus produces an external can of a dry element battery. The production apparatus comprises a notch forming mechanism (2) supplied with a plate shaped base material (7) which becomes the external can of the dry element battery for forming notches (7a, 7b, 7c) at predetermined positions of the base material, a forming mechanism (4) for forming the base material which is formed with the notches into a cylindrical shape with a joint portion located at a lower side, a turning mechanism (5) for turning the base material (7) which is formed to the cylindrical shape so that the joint portion faces up, a laser welding unit (6) for irradiating a laser beam from above the turned base material so as to join the joint portion by a laser welding and form the external can of the dry element battery, and a feeding mechanism (10, 15, 25, 40) for successively feeding the base material to the notch forming mechanism, the forming mechanism the turning mechanism and the laser welding unit.
