Serial No. 350,345 ROLLER TYPE SYSTEM, PROCESS AND APPARATUS FOR PULP REFINING A method of refining fibrous material comprising interconnected fiber-like constituents the essential components of which include cellulose filament structure and means defining protective sheathing containing said filament structure including the steps of rolling the material in separately defined relatively elongate portions comprising amounts of said interconnected constituents, during rolling maintaining the length of each said portion aligned in an orientation generally transverse to the direction of the rolling and separated from the other of said portions, applying non-cutting elements during rolling gradually disconnecting said fiber-like constituents and reducing said sheathing components thereof, exposing and loosening said filament structure from containment by said sheathing and converting said filament structure to ribbon or thread-like segments thereof while essentially inhibiting the separation of each said portion into disconnected parts prior to the completion of the rolling procedure. Preferred apparatus for refining the fibrous material includes one or more rollers at least in part having in association therewith means for the rolling of small individual portions of the material into elongate form with the means for rolling the portions including means for applying non-cutting pressure and torsional shear during rolling effective to break down the outer layer of the fiber elements and the binders which connect the outer layer to the inner filaments the exposure of which is particularly desired for quality pulp material. |
