Abstract
The invention concerns an extrusion granulator for the granulation of plastic strands gripped by a pair of feed rollers and directed over a slideway in the direction of a cutting rotor with an opposing blade. A guided air stream directed onto the slideway, and deflected perpendicularly towards the cutting rotor by said slideway, impinges on the strands carried on the slideway with such a speed that the strands are held in a parallel orientation by the air stream.
