Abstract
Conexión de protección para una máquina cortadora, provista de una cuchilla sin fin desplazable accionada por un electromotor, para materiales flexibles y sobre todo revestimientos, con alarma para frenado total-detención automática de la cuchilla sin fin mediante la desconexión y frenado del electromotor por accionamiento manual de la alarma al tocar el operario la cuchilla sin fin al desacoplar un oscilador variable, accionado con una tensión de oscilador, con un condensador en forma de cuchilla sin fin aislada eléctricamente con respecto al soporte de la máquina, caracterizada porque el oscilador variable(3) consiste en un divisor complejo de tensión (14)con elementos capacitivos, accionado en contrafase por la tensión de un oscilador y llevado con una conexión central fijada a través de un primer generador de pulsos(23) a la primera entrada de un circuito de coincidencia (24), cuya segunda entrada está accionada a través de un segundo generador de pulsos(25)directamente con la tensión del oscilador.
