The timber (2) passes in a direction of movement (3) between successive clamping roller pairs (27, 26), between which a test roller (48) imposes a flexible bending (fD) on the timber (2). The imposed flexible bending (fD) is maintained at least approximately constant by controlling a setting drive (70) by means of a computer (83). Any possible natural curvature of the timber (2) is measured by measuring elements (80, 81) and is taken into account. The thickness (d) of the timber is also measured without contact by measuring elements (81, 82). The restoring force is measured by a force measuring device (68) and the position of the test roller (48) transversely to the direction of movement (3) is measured by a distance transducer (77). From this the computer (83) calculates the local modulus of elasticity in flexure and combines this, for the final evaluation of the timber (2), with information about strength and density of the timber (2) which results from an irradiation of the timber with a fan- shaped beam of radiation (75).
