ABSTRACT:
Method is disclosed for forming encapsulated material. Centrifugal force developed by a rotating nozzle having a plurality of radial orifices is used for extruding material to be encapsulated. The nozzle is mounted for rotation about a generally vertical axis and is provided with a circumferential outside surface near its bottom inclined upwardly away from the axis of the nozzle which, when partially submerged in a liquid during rotation, impels a sheet or spray of the liquid along the circumferential surface and shears off successive leading tips of extruded material to form capsules.
