Abstract: The invention relates to a method for producing adhesively bonded wood composite products (10, 13, 24, 24a, 25a) from raw logs (1) having substantially the same raw wood length, wherein the wood composite products can be connected to form a freely selectable wood composite width and/or wood composite length, wherein substantially every raw log (1) is split in each case in the longitudinal direction into log parts (2, 20, 21) and into outer slab parts (34) and, after drying and subsequent levelling, profiling (23) is produced on opposite side surfaces (18c, 18d, 37) of each log part (2, 20, 21).

Abstract: The invention relates to a method for quality assurance in preferably finger-jointed timber (1), produced in series, with a given minimum length (12), characterized in that each piece, produced within the length (12), is loaded with increasing tensile forces at the ends (5) thereof to a threshold value, below the breaking load for a fault-free timber piece, and the length changes (DELTA 1), changing therewith, are determined over a section, or the whole length of the timber piece (1) and used as a quality criterion for the use, or the further processing of the timber piece (1). The invention further relates to a device for carrying out said method.
