Abstract
This invention relates to a method and apparatus for manufacturing seamless material-filled capsules characterized by the fact that a capsule filler material, a sol solution and a water-insoluble solution in the form of a continuous jet are fed from a triple orifice of the same core into a stream of hardening solution, the spherical drops consisting of the above mentioned three layers are completed due to their interfacial surface tensions, then said water-soluble solution of said outermost layer is caused to strike several interrupting plates to have said water insoluble layer destroyed and separated from the sol solution as a second layer to react said sol solution with said hardening solution at this instant for forming a water-insoluble film and the diameter the wall thickness of said spherical drop can be changed easily by modifying the flow speed of the hardening solution and the diameter of said orifice.
