ABSTRACT:
A method of color marking logs wherein the logs are cut to predetermined lengths in a processing machine and are colored coded with one or a combination of different colors after the cutting has taken place. The colors correspond to predetermined information related to the log such as its length and are applied to an end portion of the log during a free fall after cut-off by means of automatically controlled paint sprayers. A sprayer for color marking the log is preset prior to its actuation by a signal corresponding to the predetermined log length.
