APPARATUS FOR MEASURING LENGTH OF MOVING ROLLED STRIP Russian patent published in 2005 - IPC

Abstract RU 2254982 C1

FIELD: rolled stock production.

SUBSTANCE: apparatus includes unit for measuring length; additional unit and converter forming signal for cutting. Additional unit is in the form of two slit type sliding guides mounted with possibility of measuring distance between them according to width B of rolled strip. Length of guides l = (18 - 21)√B, width of slits (0.05 - 0.07)B. Unit for measuring length of rolled strip is in the form of optical sensor on base of light sensitive matrix having in bottom portion inlet opening. Said sensor is connected with converter. Measuring unit is spaced by distance b = (0.15 -0.22)B from one lateral edge of rolled strip and it is mounted in such a way that distance from inlet opening of measuring unit till surface of rolled strip along height is equal to 3 - 5 mm.

EFFECT: lowered metal consumption, enhanced consumers' properties of rolled strip due to high accuracy of cutting it.
