Abstract

Procedimiento y dispositivo para controlar la planeidad de una banda metálica laminada en frío, midiendo las tracciones sobre zonas diferentes de la anchura de la banda, el procedimiento caracterizado porque al ser las zonas en cuestión al menos un número de tres, se calcula la suma de las tracciones medidas en las zonas respectivas, se calcula a partir del resultado obtenido la tracción teórica en cada zona correspondiente a una tracción uniformemente repartida a lo largo de la anchura de la banda, se compara esta tracción teórica con la suma de las tracciones, antes mencionadas, efectivamente medida en la zona correspondiente y, en función de los resultados de esta comparación, se ejerce si ha lugar las acciones correctivas deseadas.
