ABSTRACT:
In a method of trimming timber pieces, in which the pieces are cross-cut at one end and thereafter are advanced to a turner, the invention includes the step of applying to each piece, prior to arrival at the turner, a plurality of marks which are registrable after the turning of the piece. The marks are applied on that side of the piece which, after the turning, shall face upwardly. Preferably, the marks are equally spaced, and are repeated from the cross-cut end to the opposite end of the piece.
