ABSTRACT:
A multi-ply solid wood structure, such as a beam, a board or a truss, and a ethod of manufacturing such wood structures are disclosed. The wood structure comprises wood lamellae that are joined together, wherein the wood lamellae are produced by a chipless separation from squared timber using a blade or a knife, and wherein the lamellae have a knife side that was adjacent to the knife during the process of separation and an opposite side that is remote from the knife side. In one embodiment, the wood lamellae are arranged in the multi-ply solid wood structure such that, when viewed from a center plane of the wood structure extending generally in parallel to the external surfaces of the lamellae of the wood structure, the opposite side of each wood lamellae is directed toward the two external surfaces of the wood structure.
