Abstract (en)
[origin: WO2022028654A1] The invention relates to a method for producing construction wood from small-dimensioned wood, having the steps of: - providing a small-dimensioned wood log which extends in a longitudinal direction and thereby has a substantially circular cross-section and tapers conically in the longitudinal direction, - separating the small-dimensioned wood log into two half logs, each of which is delimited by a central cutting surface and a parallel outer cutting surface, - trimming the two half logs so as to provide two respective flanks, said two flanks being provided so as to run towards each other along the conical shape of the original small-dimensioned wood log, and - producing a single-layer continuous board by placing and gluing the lateral flanks of multiple trimmed half logs together, wherein the half logs are arranged such that the flanks thereof running towards each other lie against each other in a reciprocal manner.
