PURPOSE:To continuously obtain a chain-like grid to increase productivity by arranging up and down a set of forming rollers on which grooves forming bones of grid for lead-acid battery are engraved and passing a lead or lead alloy sheet between rotating rollers. CONSTITUTION:A chain-like grid for lead-acid battery is formed in such a way that a set of forming rollers 2, 3 on which grooves forming bones of grid for lead-acid battery are engraved are arranged up and down same as a roller press, and a sheet material 1 comprising lead or lead alloy is passed between rollers 2 and 3 each of which rotates in an arrow direction to form chain on the sheet. Grooves forming grid bones for lead-acid battery are formed so that 2C and 3C, 2B and 3B, and 2E and 3E form a set respectively. |
