Abstract
Se revela un aparato detector de rotura de papel para detectar la rotura del papel en una sección de secado de una máquina de papel. El aparato incluye un transductor de vacío que es sensible al nivel de vacío dentro del rodillo de vacío de una sección de secado. El transductor detecta solamente el cambio brusco en el nivel de vacío del interior del rodillo del vacío producido por la rotura de la banda de papel y no es sensible al cambio gradual del nivel de vacío resultante de un aumento realizado por un operador. Un dispositivo-guía se encuentra conectado al transductor y es sensible al transductor para redireccionar la banda de papel hacia un tobogán de rotura situado corriente arriba con respecto al transductor cuando éste detecta un cambio brusco en el nivel de vacío. La disposición es tal que inhibe que la banda de papel rota se enrolle excesivamente alrededor del secador de la sección de secado.
