Floorboards are manufactured by working boards unsorted in respect of quality to predetermined width and thickness. The boards are cut where necessary to remove board sections containing flaws (12) whereupon these board sections are split along their central plane and worked and glued in end-to-end relationship on the opposite flat sides of the flawless board sections (15) which also have been placed end to end, in accordance with the preferred method of the invention. The resultant assembly is split along the central plane of the last-mentioned board sections (15), and the strips are worked, tongued and grooved, and finished. A floorboard manufactured in this manner comprises a top layer of flawless board sections (15) of varying lengths and a bottom layer including board sections (14a, 14b) which contain flaws and have been cut from the starting material to provide the said flawless board sections (15). |
