SLIT-SEPARATOR PRODUCTION METHOD, AND SEPARATOR-WOUND-BODY PRODUCTION METHOD

摘要

The purpose of the present invention is to obtain a high-quality slit separator exhibiting little fuzz in slit regions. The present invention includes: a step (S101) in which a raw fabric (S) is conveyed; and a step (S102) in which the raw fabric (S) is slit by inserting a plurality of slitting blades (72) into the raw fabric (S) such that the tangential plane angle (θ3) within tangential planes to the raw fabric (S) in the slit positions is substantially the same.
