Abstract
A super absorbent distribution system for homogenous distribution throughout an absorbent core is disclosed. A super absorbent material is injected into a stream of absorbent fluff at an opposite direction to that of the stream of absorbent fluff. The super absorbent is blasted into the peak and outer surface of a cone shaped super absorbent barrier. The oncoming absorbent fluff also contends with a similarly shaped absorbent fluff barrier. The super absorbent material slows down as it hits the super absorbent barrier and oncoming fluff, then stops, then reverses direction and flows with the absorbent fluff as a homogenous distribution of super absorbent material and absorbent fluff. The combination of super absorbent material and absorbent fluff may encounter baffle members to further distribute the super absorbent material and absorbent fluff.
