METHOD OF MANUFACTURING SEPARATOR WOUND BODY AND SLITTING METHOD OF SEPARATOR

摘要

In order to suppress the occurrence of wrinkles and winding deviation in the separator wound body, in this slit device (6), the conveyance direction of a first separator (12a) is shifted by a direction shifting roller (68) towards a first winding roller (70U), the first separator is conveyed between the direction shifting roller and a first touch roller (81U) via a winding ancillary roller (69) which is provided so as to shorten the inter-roller distance to the first touch roller, and the first separator being wound is pressed against the winding surface by the first touch roller.
