Claims (5)

Manufacture of an absorbent body in which a fiber material is supplied in a scattered state to a rotating drum having an accumulation recess formed on the outer peripheral surface, and the fiber material is deposited in the accumulation recess by suction to obtain an absorber having a predetermined shape A method,
By periodically changing the supply amount of the fiber material per unit time in accordance with the rotational movement period of the concave portion for accumulation, the portion where the basis weight of the fiber material is relatively high and the basis weight of the fiber material are relatively The manufacturing method of an absorber which obtains the absorber which has a low part.   The method for manufacturing an absorbent body according to claim 1, wherein the concave portion for accumulation generates a uniform suction force on the entire bottom surface.   The fiber material supplied in a scattered state to the rotating drum is generated by supplying a raw material sheet of the fiber material to a defibrator and changing the supply amount per unit time of the raw material sheet to the defibrator. The manufacturing method of the absorber of Claim 1 or 2 which changes the supply amount per unit time of the fiber material supplied in a scattered state to a drum periodically.   The manufacturing method of the absorber of any one of Claims 1-3 which supplies a water absorbing polymer in the air flow which conveys the said fiber material, and obtains the absorber which has a water absorbing polymer.   In the air flow that conveys the fiber material, the water-absorbing polymer is continuously supplied at a constant supply amount, and the basis weight of the fiber material is used as the absorbent in a portion where the basis weight of the fiber material is relatively high. The manufacturing method of the absorber of any one of Claims 1-4 which obtains the absorber which has more water-absorbing polymers than a part with relatively low.
