Abstract
Perfeccionamientos en trenes de laminación de fleje en tandem, del tipo que comprende una pluralidad de cajas de laminador, cada una de las cuales comprende un par de rodillos de trabajo, medios para ajustar la posición relativa de los rodillos con el fin de ajustar el espacio de separación entre los mismos, medios para medir la fuerza de separación que surge de un fleje entre los rodillos, un aparato de control automático de espesor que comprende medios que funcionan unidos a los medios de medición de fuerza de la primera caja del laminador dará generar señales de error de espacio indicadas por cambios en la fuerza de separación, y medios que funcionan unidos a la segunda caja de laminador para hacer funcionar a su medio de ajuste en respuesta a las señales, caracterizados porque los medios generadores generan señales que representan error de espacio exclusivamente y alimentan las señales a la segunda caja de laminador por medio de un circuito de retardo, cuyo circuito retarda las señalespara dejar tiempo al trasporte del fleje desde la primera caja hasta la segunda caja menos el tiempo de reacción del medio de ajuste de la segunda caja de laminador.
