ABSTRACT:
The present invention concerns an apparatus for receiving and feeding into a chipper wood to be chipped, said apparatus containing a feed conveyor receiving log bundles, a tumbling drum breaking the bundles, and a receiving conveyor. The feed conveyor is speed-controlled according to the position information of a log bundle, and the speed of rotation of the tumbling drum 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.
