Abstract
Pellets which are formed by extruding and cutting may be squashed in the latter operation. Squashing is reduced by passing a strand of extruded material downwardly under the influence of gravity and cutting the strand horizontally with a blade, preferably supporting the strand against the cutting blade by blowing gas against it when cutting.
