PRODUCTION METHOD FOR SEPARATOR SHEET, PRODUCTION METHOD FOR SEPARATOR, SEPARATOR WOUND BODY, SEPARATOR SHEET WOUND BODY, AND SEPARATOR SHEET PRODUCTION DEVICE

摘要

A production method for a separator that includes: a winding step for winding a separator (12a, 12b) on which a defect (D) has been detected onto a core (81, 53); and a first defect code application step for forming a defect code (DC2) that includes information on the position of the defect (D) in the longitudinal direction of the separator (12a, 12b) on an outermost circumferential part (86, 86b) of the separator (12a, 12b) that has been wound onto the core (81, 53) or on the core (81, 53) onto which the separator (12a, 12b) has been wound.
