A root chipper, which is simple in construction, inexpensive to manufacture, silent and economical to run and comprises a support device (1) for the log (8), the root swelling portions (9) of which are to be removed to render said log acceptable in a frame saw operation and similar fast deal sawing operations. It also comprises a support device (2) and means (3), which jointly can rotate the log in a fixed position on said support device (1). A frame (5) having a knife (6) in the support device (1) is pushed forwards by means of a hydraulic device (7, 7a) and said knife in this way cuts away, for different angular positions of said rotatable log, root swelling portions (9), 2 to 4 such cuttings ordinarily being sufficient to render said log acceptable for the sawing operation. |
