METHOD OF JOINING TOGETHER PARTS CONSISTING AT LEAST PARTLY OF WOOD OR WOOD-LIKE MATERIALS

摘要

In the method proposed, parts (A, B) consisting at least partly of wood or wood-like materials are joined together by placing at least one layer of thermoplastic (L) between the surface regions to be joined and these regions are excited mechanically, e.g. by ultrasonic waves. The at least one layer of thermoplastic may for instance be a coloured or colourless paint layer (L) which carries out the function of a sealable coating in the regions of the surface to be joined and a protective and/or colouring function in other regions of the surface. Suitable for use with the method proposed are prior art paints with a thermoplastic component, e.g. acrylic paints. Friction welding or orbital welding can be used instead of ultrasonic sealing.
