The height positioning of the rotor (4) and thus the play between the wings (3) of the rotor and the sieve (5) of the machine are adjustable by means of an adjusting system (20 - 26), even during operation of the machine.

Why it's free to use
- Filed December 30, 1996 and granted June 10, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 30, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 30, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
