ABSTRACT:
In a milling apparatus for removing root swellings from timber logs the log is received on two spaced apart supports with the butt-end of the logs freely overhanging from the supports. A holder-on urges the log against the supports. The holder-on as well as the supports comprise means for rotating the log relative to the holder-on as well as the supports. Under the overhanging butt-end of the log a milling cutter cylinder is arranged for machining the rotating log on the bottom side of the log so as to remove the swellings but no useful wood material.
