Title:
FIBROUS SHEET AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/046653
Kind Code:
A1
Abstract:
A method for manufacturing fibrous sheets of non-elastomeric fibers, the method comprising: a feed-out driving process configured to adjust a conveying speed of a continuous fibrous sheet; and a gather forming process configured to supply the continuous fibrous sheet to an engagement portion of a plurality of gear teeth each extending in a direction intersecting with a moving direction of the continuous fibrous sheet and to form undulating gathers on the continuous fibrous sheet, wherein: a feed-out speed in the feed-out driving process is faster than a feed-out speed in the gather forming process; the continuous fibrous sheet in a state of being substantially not stretched in the moving direction is supplied to the gather forming process so as to form the gathers on the continuous fibrous sheet without mechanically fracturing the non-elastomeric fibers; and the continuous fibrous sheet is cut out into a predetermined size.
