Rotor 1 rotates about fixed axis A with rigidly attached round eccentric 3. Follower 4 oscillates about fixed axis B and carries roll 6 which rolls along the contour of eccentric 3. Link 5 is connected by turning pairs C and D to follower 4 and to link 2 which oscillates about fixed axis F. As rotor 1 rotates, wood is fed in by link 2 and is cut up into chips by rotary knife a, mounted on rotor 1, and stationary knives b, mounted in the fixed housing.
