Title:
鉛蓄電池の製造方法及びその装置
Document Type and Number:
Japanese Patent JP4848597
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a lead-acid battery and its device, preventing the corrosion of an edge part of a cell of a grid by inclining a gap surface 1c between projection parts 1a of a disc cutter 1, and preventing capacity drop and short life of the lead-acid battery. SOLUTION: A rotary type expander disc cutter 1 is formed in such a way that conical projection parts 1a whose top 1b is inclined forward in the rotation direction are projected from a circumferential surface A at distant equal intervals, a gap surface 1c which is a circumferential side surface between the projection parts 1a is formed on a surface where all contact surface coming in contact with the gap surface 1c is inclined toward the center side in more front side than the contact surface coming in contact with the circumferential surface A which becomes the same angle position on the rotation shaft of the disc cutter 1. A slit 2a in which a knotting part 2b is inclined is formed in a lead sheet 2 with the disc cutter 1.
