Title:
SHEET-PIECE PRODUCING METHOD, SHEET-PIECE PRODUCING APPARATUS, AND ABSORBENT-BODY PRODUCING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/107333
Kind Code:
A1
Abstract:
A sheet-piece producing method according to the present invention includes: a first cutting step in which a raw-material sheet (10bs) is cut in a transport direction (MD) thereof by a first cutting mechanism (5A) to obtain a plurality of strip-shaped narrow sheets (10bt); and a second cutting step in which the narrow sheets (10bt) are cut in a direction (CD) intersecting the transport direction by a second cutting mechanism (5B) to obtain a plurality of sheet pieces (11). The second cutting step is performed by supplying the narrow sheets (10bt) between a cutter roll (53) and an anvil roll (54), which axially rotate, in the second cutting mechanism (5B). The circumferential velocity (V1) of the roll (53) is set to be higher than the velocity (V0) at which the narrow sheets (10bt) are supplied between the rolls (53), (54).
