Abstract: A distinctive apparatus for forming an absorbent body includes a forming chamber, and a fiber delivering mechanism for providing a flow of fibrous material within the forming chamber. A forming layer, which is located in the forming chamber and is movable therein, receives deposit of the fibrous material thereon. A conduit mechanism supplied a flow of dispersed bodies of high-absorbency material, which enter the forming chambers and intermix with the flow of fibrous material thereon. A regulating mechanism controls a velocity of the flow of high-absorbency material into the flow of fibrous material to thereby form a selected distribution of high-absorbency material within the fibrous material deposited onto the forming layer.
