One of the characteristic parameters of the unedged boards is their taper coefficient. It was found that when sawing logs in parallel to their longitudinal axis taper coefficient of central and lateral unedged boards is always higher than in the original log and it increases with distance of the board from the center of the vertex end of the log and increase of its taper coefficient, while in parallel generatrix cutting (by taper) taper coefficient of central and lateral unedged boards is always less than the initial log has and it decreases with distance of the board from the center of apex end of log and decrease of its taper coefficient.
