Document Type and Number:
WIPO Patent Application WO/2016/104507
Kind Code:
A1
Abstract:
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.
