Abstract: Method and apparatus for screening peat moss material. The method comprises the steps of forming an aqueous slurry of peat moss material and flowing the slurry on a screen to separate fines from coarser particles in the slurry. A spray of relatively large water drops is directed at the slurry to agitate the coarser particles blocked by the screen in order to dislodge fines adhering thereto, whereby the fines freed from the coarser particles are allowed to egress the slurry through the screen. The water spray also has the effect of clearing the screen of fines which clog the screen openings. The invention also comprehends a method and apparatus for screening peat moss material, comprising the steps of flowing an aqueous slurry of peat moss material on a sieve to extract from the slurry excessively large particles, and washing the rejects remaining on the sieve to dislodge therefrom smaller particles of acceptable size which are returned to the slurry.

Abstract: This invention relates to a novel absorbent structure and absorbent products containing this absorbent structure. More particularly, the absorbent structure of this invention is a flexible and retentive reservoir layer comprising a perf-embossed or tenderized peat board material.

Abstract: Dry laid board comprising peat moss is provided and made by harvesting peat moss having a degree of decomposition of H-1 value as measured by the Modified Von Post Scale, individualizing the harvested peat moss, drying the individualized peat moss and entraining the peat moss in a gas stream. The entrained peat moss is then condensed to form a low density peat moss containing board which is subsequently calendered for use in such products as dressings, diapers and sanitary napkins.
