    摘要： A method an apparatus for reclaiming face fibers and polypropylene and/or polyvinyl chloride backing material from rolls and pieces of post-consumer carpet. The system includes a separator for separating the face fibers from the backing and for separating latex and carbon calcium powder from polypropylene backing. An extruder is provided for extruding the face fibers separated from the backing into extrusions, and a pelletizer pelletizes the extrusions. A roller opener opens the polypropylene backing into fibrous portions and also cleans such fibrous portions. Alternately, a granulator can be provided that chops and grinds the polypropylene or PVC backing into fragments after the separation of the face fibers from the backing. A heat source heats the PVC fragments, and also the polypropylene fragments (thereby separating the latex therefrom), and ultimately melts such fragments. Reclaimed fibers can be pelletized, made into extrusions, used in non-woven products and in other manners.

    摘要： An extruded composite structural artificial lumber product is manufactured from wood fiber and polyethylene, including recycled polyethylene, by reducing the wood fiber and polyethylene each to a finely divided particles, mechanically mixing the wood fiber and polyethylene particles together with a measured amount of a powdered endothermic foaming agent, mechanically mixing the mixture, without pre-pelletization, in a twin-screw extruder where it is compressed and heated until it becomes plastic and homogenous, and then extruding the plastic mixture, using vacuum to remove vaporized moisture and other excess volatiles, through a molding die which forms structural profile of the desired product. The endothermic foaming agent ingredient causes greater expansion in the center of the extruded profile, thereby compressing a greater proportion of plastic material against the sides of the extrusion die, increasing the density and strength on the outside of the extrusion, and reducing the density (with no significant loss of overall strength) on the inside. The resulting extruded artificial lumber product has a specific gravity of about 1.0, plus or minus 20%, with no significant variation in dimensions after cooling.

    摘要： A method is disclosed for molding parts. The system comprises a plasticator and press. The plasticator is capable of receiving a plurality of molding materials comprising a predetermined amount of at least thermoplastic polymers and long reinforcing fibers, such as glass fiber. The plasticator is characterized in that it is capable of simultaneously receiving contaminated molding materials and relatively long glass fibers and molding them into a billet wherein the fibers remain substantially undamaged. The billet is subsequently placed in a compression molding press where other materials may be molded or applied to its surface. The method is further characterized in that a single thermal rise is used to plasticate the molding materials. The system employed by the method comprises a plasticator having a screw, a screw drive system, a plurality of heaters and control system to control the pressure and temperature in a barrel of the plasticator so as to create a billet having certain predetermined billet characteristics (such as a desired volume and/or density).

    摘要： A method of continuously fabricating a cushiony recycled plastic floor tile or wall cover wherein a single-ply sheet, made up substantially of recycled membrane and a proportion of discrete fibers sufficient to create a cushion effect in the tile, is extruded. The fibers are reduced in length by cooling the sheet extrudate produced, chopping the sheet extrudate into particles in which the fibers are reduced in length and then passing the chopped extrudate into the extruder to reextrude it. When size reduction is achieved, the hot substrate proceeds immediately into the nip between laminating rolls and a preheated cover film selected from the group comprising transparent sheet, colored sheet, and sheet with decorative imprinting is passed on into the nip with the substrate. Compressive pressure is applied by the laminating rolls to autogeneously heat weld the substrate and cover film in surface to surface sealed contact without the imposition of air bubbles or wrinkles between them. The welded product is then cooled and cut into discrete sizes.
