<p>1. Method for the fixation of knots (4) in a board (3), characterized in that a mechanical strain action is exerted at least on one of the faces (5) of said knot at the surface of the board, said strain producing a lateral upsetting of the material of said knot (4) against the lateral surface of its housing in the board (3), said upset material increasing the adhesion between knot and board and contributing to bind rigidly the knot to the board.</p> |
