Abstract
A method and an apparatus for measuring a shape wherein an article having a cross sectional shape to be measured is subjected to scanning along a direction of a width of the article by means of a pair of displacement sensors, wherein the article is moved in a constant direction and the displacement sensors are located substantially opposing to each other with the article being therebetween, and displacements of a surface on one side and of a surface on another side of the article are detected at every constant pitch, then the cross sectional shape is obtained by processing the detected displacements. The method and the apparatus enable to carry out accurate on-line measurement of a cross sectional shape of an article and provide improved quality control.
