청구항

A method for pelletizing a thermoplastic material comprising: supplying a flow of molten thermoplastic material, forming said flow of molten material into a plurality of individual streams having substantially equal cross sectional area and substantially equal stream flow velocity at a preselected plane of reference by passing each said stream through a passageway having an upstream portion of a first length and a first relatively large cross sectional area and a downstream portion of a second length and a second relatively small cross sectional area, ea...
