Abstract:
The present disclosure provides a method of forming a laminated wood product, which is adapted for receiving a load in a direction perpendicular to a principal fiber direction of the wood. The method comprises cutting a log (2) along the principal fiber direction of the log, into a plurality of wood lamellae (20a, 20b), such that the wood lamellae are formed as radial sections of the log, forming the wood lamellae (20a, 20b) to provide each wood lamella with a trapezoidal cross section, whereby the wood lamellae present a respective planar major base surface (bs1) that is formed at a radially outer part of the log (2) and a respective planar minor base surface (bs2) that is formed at a radially inner part of the log (2), arranging the lamellae (20a, 20b) as at least one layer in which planar major base surfaces (bs1) of immediately adjacent lamellae (20a, 20b) face opposite directions, and gluing together the lamellae (20a, 20b) side surface to side surface (ss1, ss2) such that a wood billet is formed. The method further comprises arranging the wood lamellae (20a, b) such that the major base surfaces (bs1) of immediately adjacent wood lamellae taper in opposite directions, and the gluing comprises wet gluing.
