<p>PURPOSE:To measure the intrinsic bending of a long material simply and accurately. CONSTITUTION:A long material is horizontally supported at the two points of supporting stages 11 and 12. The attitude of the long material is changed on the supporting stages. The positions of the long material 10 are detected with position detectors 13, which are provided at both end sides of the long material and at least one or more places between both ends. The bending of the long material 10 is computed based on the position data outputted from the position detectors 13. Thus, the intrinsic bending without the effect of the restriction from the outside and without the deflection component can be detected.</p> |
