Abstract
In pelletizing apparatus, an orifice plate forms plastic strands, the orifice plate having a distributor channel at its inlet side in the form of a grooved annular inlet. A cutting plate is provided with outlet openings which are connected to the distributor channel by inlet channels arranged around the distributor channel in successive adjoining relation. In order to improve the melt flow in the inlet region, the distributor channel has a cross-sectional width in the radial direction that is less than the radial extent of the inlet channels where they are joined to the outlet openings. The longitudinal axes of adjacent inlet channels are arranged at an angle of inclination relative to each other.
