ABSTRACT:
An apparatus and method for continuously making a mixture of viscous material with solid material segments, which utilizes a pair of spaced mixing rolls (26, 28) for dragging the viscous material (42, 44) and the solid material segments (66, 68) into a gap (34) between the mixing rolls to permit the material to be mixed together to form an impregnated compound (82). Each roll has a hopper (36, 38) having an opening (54) and an associated coating blade (46,48) for depositing of layer (42, 44) of desired thickness of the viscous material on the mixing rolls. A solid material cutter (70, 72) is located above and associated with each mixing roller, to provide distinct stream (66, 68) of solid material segments in a uniform rainfall onto the layers of viscous material as the layers emerge from the coating blades. Both the thickness of the viscous layer applied to the rolls and the gap between the rolls are adjustable to accommodate a wide variety of recipes and to produce a variety of useful compounds. A funnel (104 ) or a compressor unit (86) is associated with the mixing unit (22), for directing the impregnated compound into a receptacle (98, 108). A turntable (102) or a conveyor belt (106) is associated with the compressor or funnel for serially positioning an empty receptacle to receive a predetermined quantity of impregnated compound for shipment to a user of injection molding equipment or the like.
