A log-levelling machine having at least one rotary cutter in the shape of a conical disc and a device for advancing logs in their longitudinal direction toward the rotary cutter or cutters. The machine operates to flatten the logs on their lateral sides by cutting the excess material into chips. According to the invention, that portion of each rotary cutter which is located next to the flattened surface of a log which is being cut is provided with a set of teeth adapted to cut chips of substantially smaller thickness than the chips cut by the remaining teeth of the cutter. |
