Abstract: A method of manufacturing a molded paper pulp article from a fiber slurry involves the vacuum deposition of a layer of wet paper pulp onto a forming mold, the separation of the wet layer of paper pulp from the forming mold and the pressing and shaping of the layer of wet paper pulp at a solids content of from about 5 to 20 percent solids. A finished product molded paper article is prepared having improved surface appearance and detailing and improved mechanical and physical properties.

Abstract: A method of waste paper recycling wherein the unwanted portions of waste paper such as those containing a binder adhesive are separated from the remaining paper material. In the binding of books, catalogues, directories, pamphlets, magazines and the like, adhesive material is provided having a magnetic substance therein and in subsequent recycling, the waste paper from these books and magazines is cut into a plurality of relatively small pieces. These pieces are passed through a magnetic field wherein the portions containing the adhesive having magnetic material therein, are separated from the remaining non-magnetically attracted sheets of paper.

Abstract: A method is provided for converting waste paper materials into more useful forms for uses such as plant mulches, lightweight concrete aggregates, fertilizers, animal feeds, chemical food stock and other materials, fuels and uses such as recycling paper processes. Waste paper materials including corrugated box board, paper board, paper of all types, etc. is available as a raw material in a wide variety of forms such as sheets, bales, bundles, boxes, shavings, clippings from box making operations, magazines, newspapers, etc. and these products are much more useful for the purposes and uses mentioned after treatment and conversion into a more useful form. This conversion includes the steps of bale breaking, sorting, trimming and/or cutting these raw materials into pieces of relatively limited size for feeding across a cutter bar into a rotating knife cylinder wherein the raw materials are cut into small pieces.
