ABSTRACT:
An absorbent product manufacturing apparatus including a pulp feed mechanism (2) for feeding a pulp sheet along a lower surface of a pulp guide part (2411) and a pulp crushing mechanism (3) for crushing the pulp sheet from the pulp feed mechanism (2). The pulp crushing mechanism (3) crushes the pulp sheet with a first crushing cylinder (312) and a second crushing cylinder (322). The crushing cylinders are disposed so as to be inclined with respect to a direction of feeding the pulp sheet. This reduces the force necessary to draw the pulp sheet in the feeding direction and suppresses an increase in the movement speed of the pulp sheet in crushing a rear end portion of the pulp sheet. As a result, it is possible to increase the amount of crushed pulp to be generated in a unit time and to maintain uniformity in the quality thereof.
