Patent ID: 7772457

Claim:
A manufacturing method for manufacturing an absorbent body, comprising: transferring a stripe-shaped absorbent body base, including an absorbent element obtained by mixing at least pulp with super absorbent polymer, through a pair of rollers that are provided to be opposed to each other with a predetermined distance therebetween, wherein at least one of the rollers is a press print processing roller that has a plurality of processing projections with a predetermined layout on a circumference surface; forming a plurality of linear pattern elements on at least one surface of the absorbent body base, wherein the linear pattern elements are formed by being squeezed by the processing projections so as to have a groove-like shape, and wherein the plurality of linear pattern elements are individually spaced from one another and dispersed in a staggered manner; and cutting the absorbent body base to have a predetermined size after the linear pattern elements are formed, wherein the linear pattern elements are formed in a shape so that an orientation angle, which is a degree of inclination of the linear pattern elements to a transfer direction of the absorbent body base, is 50 degrees or less at any portion; and wherein the plurality of linear pattern elements are arranged in straight lines so that a constant number of the linear pattern elements are formed on any of the straight lines extending in a width direction orthogonal to the transfer direction of the absorbent body base, the straight lines being defined anywhere along the transfer direction of the absorbent body base, and wherein distances between each of the constant number of the linear pattern elements in the width direction are equal to one another.
