Abstract: In a separating device for a wood chipper comprising a chipper rotor housing and a chipper rotor rotatably journalled therein it is proposed in accordance with the invention to provide the separating device with a plurality of ribs defining between themselves spaces through which wood chips of a predetermined maximum size and less are passing to an outlet of the chipper rotor housing. Each rib has an arc-shaped edge facing the chipper rotor with a radius which has its center coincident with the axis of rotation of the chipper rotor, said edge being arranged at a predetermined distance from the cylindrical surface of the chipper rotor in order to form a free passage for pieces of material which are larger than the desired maximum size of discharged chips.

Abstract: In order to enable the setting of the inlet funnel of a wood chipper to different positions for adaptation to prevailing operating conditions including the type of material to be chipped, it is proposed in accordance with the invention that cooperating bearing means be arranged on the chipper rotor housing of the wood chipper and on the frame supporting the chipper rotor housing so that the chipper rotor housing and the inlet funnel are pivotal around the axis of rotation of the chipper rotor.
