Abstract
A pelletizing apparatus including rotating cutting knives which are moved against a die plate to sever the plastic strands into pellets. The knives are driven such as to ensure a constantly parallel contact without any partial lifting of the knives from the die plate caused by the unilateral fixing of the cutting knives. This is achieved by a coupler mechanism which connects the knives to the hub of the knife head and ensures a parallel arrangement of the cutting edges of the knives over their entire length relative to the die surface.
