ABSTRACT:
In a method for profile chipping, the necessary chipping out of wany-edged corners laterally defining a side board (4) to be separated is carried out in such a manner that firstly in a direction perpendicular to the trunk axis saw incisions (6) are made to the full depth of the corner but that material adjacent the saw incision (6) is simultaneously chipped out by chipping blades only to a lesser depth, and in a second working step in a second direction perpendicular to the first direction (17) remaining corner material (20) is chipped out by means of chipping blades and simultaneously a second saw incision (18) is made. The side board (4) exposed in this manner is separated by a saw severance cut. This provides throughout corner faces worked by saw cut which do not have any material splits due to chipping blades.
