Abstract (en)

[origin: WO0143928A1] The process is used for making individual wood boards (52) from a plurality of wood pieces (10). In this process, wood pieces (10) of similar length and are joined side by side so as to form a panel (30). The panel (30) is then cut in a longitudinal direction with reference to the wood pieces (10) into panel sections (40) having a similar width. These panel sections (40) are jointed end to end to form a continuous wood board (50), which is then cut into individual wood boards (52). This process allows to manufacture wood boards (52) with a high degree of structural integrity and dimensional stability. It also allows to efficiently use small wood pieces (10) that could have been considered otherwise waste or low-grade materials, thereby increasing the yield of the sawmill.
