Abstract

A pelletizer with a rotatably drivable cutter head for dividing material strands output from a die plate into pellets, the cutter head being drivingly connected to a drive motor via a drive shaft, and with a feed device for axial adjustment of the cutter head relative to the die plate in the direction of the cutter head axis of rotation. A spindle element of a spindle drive stage of the feed device is configured as a spindle sleeve which is axially firmly seated on the rotating drive shaft between the drive motor and the cutter head. The drive shaft is connected to the cutter head in an axially-fixed and rotationally-fixed manner and transmits the axial movement of the spindle sleeve to the cutter head.
