Abstract

In a method which is carried out in a sawmill plant, blocks (B, b) are produced which are sawn from timber logs and have two plane-parallel sides (3, 4) intersecting green surfaces (1, 2) of the piece of timber. The blocks are irradiated in a measuring zone, such that the green surfaces will appear in contrast to said planar sides, and the intersections (5-8) between green surfaces and planar sides can be detected by photoelectric means. By determining the positions of said planar sides relative to said detecting means, the coordinates of the intersections are obtainable in a plurality of points in the longitudinal direction of each block. The method and the plant according to the invention make it possible to supervise how the blocks are sawn and to release an alarm signal in the event of an unacceptable defect.
