摘要： The present invention concerns an apparatus for receiving and feeding into a chipper wood to be chipped, said apparatus comprising a feed conveyor (12) receiving log bundles (1'), a tumbling drum (13) breaking the bundles, and a receiving conveyor (7'). The feed conveyor (12) is speed-controlled according to the position information of a log bundle (1'), and the speed of rotation of the tumbling d rum (13) is adjusted depending on the amount of wood discharged from the drum. The position information of the log bundle is received for example from the torque moment or input power of the drives of the drum. Thereby the speed of the feed conveyor, respectively the rotation speed of the drum, is set to slow down as a result of the increasing toque moment or input power of the drum, respectively to speed up as a result of the decreasing torque moment or input power.

摘要： The invention concerns a method for clamping a knife (1) of a disc chipper, wherein the knife (1) is pressed from the knife disc (4) via knife clamp (2', 23) against a wear plate (3) in a diagonal position (α) with respect to the plane of the knife disc with a compressive force (N) substantially parallel with the axis of the knife disc. According to the invention, the compensating force of the force directed to the knife clamp, caused by the diagonal position (α) of the knife and transversal to the compressive force (N) is exerted to the wear plate.

摘要： The present invention relates to method for separating loose bark from a flow of debarked wood logs are conveyed substantially in the direction of their longitudinal axis along a substantially horizontal conveyor track. During their travel, the logs are forced into unidirectional accelerating rotation that simultaneously moves the logs laterally. An accelerating rotary motion is advantageously imparted to the logs on a rolling ramp adapted between two conveyors operating at different height levels.
