  • Patent number: 4251195
    Abstract: Apparatus for making miniature capsules having a capsule-forming orifice defined by the open ends of two coaxial conduits. The inner conduit defines a central opening in the orifice and the outer conduit defines an annulus circumferentially of the central opening. Filter-content material for the individual capsules is extruded as a stream through the central opening and a settable coating liquid material is extruded as a thin film sleeve circumferentially of the filler-content material stream. The film sleeve and the stream of filler-content material pass through a cooling liquid which is flowed through a fixed nozzle downstream of the extruding orifice. The nozzle has an inlet section with converging inner surfaces and a uniform diameter downstream of the inlet section. The cooling fluid, the film sleeve and filler-content stream therein all pass through the nozzle.
