Method primarily in scaling, sorting, processing, cuttingup and the like of elongate timber items (1), such as logs or elements thereof with two substantially parallel, longitudinal surfaces achieved by processing, preferably during longitudinal feed of the item, including determination of a given lateral position and/or form of the timber item at at least one position along the item, a cross-section or cross-sectional element, with the aid of sensing means (3). The method is particularly distinguished by the determination taking place with the aid of touch-free distance-sen-sing means (3) with predetermined measuring directions, preferably fixed and discrete, for determining distances to at least two measuring points (5) on the surface (1') of the timber item (1), said measuring points being substantially in a cross-section or cross-sectional element of the timber item and on either side of the reference line (6) across the cross-section or cross-sectional element, said sensing taking place in two completely or partially counter-directed measuring directions (4), which, as seen in the longitudinal direction of the timber item, substantially meet or intersect each other at a point (7) preferably situated on said reference line (6), where the respective measuring direction (4), seen in the longitudinal direction of the timber item, forms and angle (.alpha.) to the reference line (6), and/or taking place in at least two measuring directions (4) parallel to the existing processing plane (4'), these measuring directions being parallel, as seen in the longitudinal direction of the timber item to said reference line (6), the distance information thus obtained being primarily utilized for determining a given lateral position and/or shape. The intention also relates to an apparatus for carrying out the method. |
