摘要：An apparatus and method for forming discrete granules from a flow of moltenplastic material is disclosed. The apparatus includes a tube having an end surface throughwhich the molten material flows and a discharge plate having an opening therethroughdisposed adjacent the tube. The discharge plate is movable with respect to the endsurface of the tube. A pressure medium accumulating region is disposed adjacent the endsurface of the tube. In operation, the molten material flows through the tube and intothe opening of the discharge plate. The end surface of the tube and the discharge platemove into and out of contact on a periodic basis such that the tube and discharge platefunction as a valve. The periodic opening and closing of the valve allows introduction ofdiscrete amounts of the pressure medium into an annular gap formed about the flow ofthe molten material and between the end surface of the tube and the discharge platesuch that the pressure medium concentrically surrounds and symmetrically divides themolten material into granules.
