Abstract:
1. A method for producing a panel-type component having at least three layers of boards disposed parallel to a plane of the component, with the boards of the at least three layers being connected to one another without glue by dowels which extend substantially transversely to the plane of the component, comprising the steps of: (a) placing at least three layers of boards on top of each other so that the boards in adjacent layers extend in different directions, (b) applying a compressive force to the at least three layers of board so that the at least three layers of boards are tensioned against each other, (c) drilling a plurality of bores through the boards of the at least three layers of boards of step (b), (d) providing a plurality of dowels which have been compacted in a radial direction, and (e) inserting the radially compacted dowels of step (d) into said bores while the boards of the at least three layers of boards are compressed so as to connect the boards of the at least three layers of boards together.
