Patent number: 9060898Abstract: A device for manufacturing an absorbent body by depositing on a deposit portion liquid absorbent fiber contained in a first gas flowing through a duct. The device for manufacturing an absorbent body includes the deposit portion that travels along a predetermined travel path, the duct that distributes the liquid absorbent fiber from a distribution opening placed opposing the travel path, a particulate matter discharge tube, a tip end thereof being introduced into the duct, that discharges a second gas having particulate matter mixed therein from a discharge hole of the tip end, and an operable throttle portion that throttles a flow path of the particulate matter discharge tube to change discharge distribution of the particulate matter. The operable throttle portion is operated in conjunction with the travel of the deposit portion.Type: GrantFiled: January 27, 2012Date of Patent: June 23, 2015Assignee: UNICHARM CORPORATIONInventor: Kazuhiko Hoshika
