Abstract
PURPOSE: To avoid the effect of bad ambient environmental conditions for measured parts, by providing a means rejecting the adhered materials in close to the front and back side of strip at upper stream and further providing a means preventing the scattering of laser light.
CONSTITUTION: The light reception time of laser light from the emission from an upper laser light radiator 11 to an upper detector is measured at a time measuring circuit 15. Further, the light reception time of laser light from the emission from the lower laser light radiator 12 to the lower detector 10 is measured at a time measuring circuit 21. The time measured at time measuring circuit 15, 21 is input to a calculation circuit 16 to calculate the sectional shape and flatness of the strip. To remove the foreign material adhered to the front and back sides of the strip, an air- blow pipe 13 is provided at a suitable location at the upper-stream before the detecting point. Further, air-blow upper and lower ducts 5, 6 are provided to prevent scattering of the laser light.
