Abstract:
In making bodily fluid absorbent pads quantity of scrapped material is reduced. A bodily fluid absorbent pad (liner) 10 has a shape symmetric in a longitudinal direction P as well as in a transverse direction Q. A dimension of the pad 10 in the transverse direction Q is larger in opposite end regions 31, 32 than in an intermediate region 33. The pad 10 is formed along opposite side edges 11a, 11b with first and second compressed lines 21, 22. Paired compression rolls 302 are used to form the first and second compressed lines 21, 22, and at least one roll constituting the paired compression rolls 302 is formed on a peripheral surface thereof with compressing units projecting from the peripheral surface. The compressing units are arranged in a circumferential direction to form one row and at least one additional row, which is adjacent to the one row in an axial direction of the roll. In each pair of the adjacent rows, there is an offset between the compressing unit in the one row and the compressing units in the other row in the circumferential direction.
