ABSTRACT:
A method of manufacturing hollow furniture parts, such as table legs comprises conveying wooden laminae to a work station to form the furniture parts. The number of wooden laminae conveyed to a modeling unit provided with polygonally, preferably squarely arranged guide surfaces corresponds to the number of said guide surfaces. The wooden laminae slide across the guide surfaces while abutting said surfaces. The longitudinal edges of the individual lamina are undercut so that the laminae form a prismatic, hollow tube subsequent to being assembled. The side surfaces of said tube are mitred along the longitudinal edges of the tube, and the wooden laminae are glued together in pairs by means of a fast-drying glue applied shortly before the laminae reach the modeling unit. Support and/or end blocks are then optionally inserted in and glued to the inside of the prismatic tube. Finally the tube is cut into small pieces corresponding to the furniture parts. This method enables the manufacture of furniture parts with prismatic shape in a simple manner while avoiding such steps in the process resulting in considerable inner stresses in the wood.
