<p>The process for making a wood board (10) comprises the steps of: a) providing elongated pieces of wood (12) each from a coniferous wood and each having a rectangular cross section; b) detecting an average fiber density of each of the pieces of wood; c) selecting among the pieces of wood those having an average fiber density at least equal to a predetermined fiber density; d) planing off edges of the pieces of wood selected in step c); and e) bonding side by side the pieces of wood planed off in step d) by means of their edges to form the wood board. The board produced thereby shows excellent mechanical characterictics. An advantage of the present ivention is to provide a process for making high strength lumber products from coniferous trees which are traditionally considered as nonstructural wood.</p> |
