ABSORBENT BODY AND DEVICE FOR PRODUCING SAME

摘要

An absorbent body forming satisfactory connections while webs are conveyed at a high speed includes at least two sheets of nonwoven fabric overlapping each other; connections at which the nonwoven fabric sheets are connected together; and an absorbent material disposed between the nonwoven fabric sheets at a small region encircled by the connections. When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections is formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and the connection is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, and simultaneously arranged in a row parallel to each other, and the minimum number of connections per row is at least 45% of the maximum number of connections per row.

主权项

1. An absorbent body comprising:
at least two sheets of nonwoven fabric overlaid with each other; connections for connecting together the nonwoven fabric sheets; and an absorbent material that is disposed in a small region encircled by the connections between the nonwoven fabric sheets, wherein as for the connections, when viewed in a direction perpendicular to a main surface of the nonwoven fabric sheet, a plurality of the connections are formed with spaces therebetween on each of sides of imaginary polygons that compartmentalize the nonwoven fabric sheet and that arc adjacent to each other, wherein the connections is arranged at least on a middle part of the side common to the imaginary polygons adjacent to each other, and wherein: the connections are formed sequentially; the connections formed simultaneously are arranged in a row; a plurality of the rows of the connections formed at different times are parallel to each other; and a minimum number of the connections per one of the rows is equal to or greater than 45% of a maximum number of the connections per one of the rows.
