Definitions

• the machine is simple to mount and install and it is com ⁇ pactly constructed, which makes it easy to adapt the machine to existing chain/hook conveyors for timber. It can also easily be installed on inclined timber chain conveyors, because the machine does not have to stand strictly horizon- tal.
• the cutter unit is elevated such that it works agains -.-.the top surface of the log, thereby providing ample space for the wood chips to accumulate beneath the machine and for the arrangement of means for removing the wood chips in the area beneath the cutter unit and the root end of the log.
• the holding means is constructed
• a cutter unit .4 adapted to be 5 raised and lowered is disposed adjacent to the holding means 1 with its axis of rotation extending in the longitudinal direction of the log 3, for working contact against the root end 3 1 of the log.
• the holding/rotating means comprises an upper member la and a lower member lb, and at least the lower 0 member lb is adapted to be raised and lowered for elevating the root end 3* of the log 3 into contact with the upper holder member la, in which position the log 3 is rotated and simultaneously milled off by the cutter unit 4, while the top end 3" of the log, which is situated farther forward in 5 the direction of transport, remains supported by the conveyor 2.
• the conveyor 2 in the example shown ( Figure 1) is formed with a V-shaped cross section which prevents the top end 3" of the log from twisting out of the conveyor as the log rotates in connection with the milling off of the thickened root portion.
• Figure 1 shows a motor 12 mounted on the arm 10 of the cutter unit 4, whose drive disk via a V-belt or chain 12' is connected to a corresponding disk 4' on the cutter unit 4.
