Patent number: 9871268Abstract: A secondary battery manufacturing method enables smooth pulling of a separator by guide members by inhibiting a phenomenon in which, when the separator is being pulled by the guide members, the separator moves in the width direction and rattles. The method includes pulling in a separator by guide bars to zigzag-fold the separator; and suspending the separator between the guide bars via a suspension roller while locating buffer rollers at a predetermined descending position, the buffer rollers being disposed between support rollers for supporting the separator at midpoints upstream, in the transport direction of the separator, of the suspension roller, the buffer rollers being ascendable and descendable in contact with an upper surface of the separator to be adjustable vertically, and allowing the buffer rollers to ascend in accordance with movement of the guide bars, thereby supplying the separator of a length pulled in by the guide bars.Type: GrantFiled: October 17, 2012Date of Patent: January 16, 2018Assignees: ELIIY POWER CO., LTD., NAGANO AUTOMATION CO., LTD.Inventors: Hiroshi Sato, Seiji Yamaura
