Abstract
Abstract The surfaces of a rolled product the distance between which is being gauged are illuminated with light pulses sent out in the form of a fine line. The light lines reflected from the surfaces are projected onto the screen of a single electron-optical storage element in such a manner that the distance between the line images is proportional to the distance being gauged. The distance between the images of the fine lines on the screen is measured during the time interval between consecutive lightimpulse transmissions. An apparatus for gauging the linear cross-sectional dimensions of a rolled product comprises a slit-diaphragm impulse light source to form a fine light line, and an optical system to present the reflections from the opposite sides of the product in a common plane. This plane contains the screen of an electronoptical storage element. The apparatus comprises an electronic means for measuring the distance between the lines on the screen.

Claim 1
Independent Claim
116 words
A method for gauging the linear cross-sectional dimensions of a moving rolled product, said method comprising the steps of: transmitting at intervals pulsed light in the form of a fine line to simultaneously illuminate areas on opposite surfaces of the rolled product, the distance between which areas is being gauged; projecting images of the fine light lines reflected from the surfaces of the rolled product onto the screen of an electronoptical storage element such that the distance between said images on the screen of the storage element is proportional to the distance being gauged; and measuring the distance between the images produced on the screen of the electron-optical storage element within the interval between transmitted pulses.
Claim 2
Independent Claim
