Abstract:
1. A method for compacting a surface of a wooden workpiece, the method comprising: providing a wooden workpiece from a group selected from at least one of a solid wooden workpiece, a workpiece manufactured from materials similar to wood, bamboo, reed, other wood-based materials, plywood, chipboards, wood-containing paper, and paper enriched with resins; heating a surface of the wooden workpiece in at least partial areas—while preventing the entry of oxygen--by supplying energy to the surface, which energy supply produces a frictional relative motion on the wooden workpiece and hence a heating and a destruction of the cell structure thereof; placing the wooden workpiece under pressure until a thermoplastic adhesive substance coming from the wooden workpiece is formed; and compacting the surface and a volume area beneath the surface under application of pressure while being cooled.
