Abstract

Dispositivo protector de hilos para máquinas textiles, que detecta un único hilo y en el caso de hilo detenido, roto o flojo emite una señal eléctrica que se aprovecha para funciones de indicación o de maniobra en la correspondiente máquina textil, caracterizado porque el hilo tensado y enmarca pone en rotación un rodillo y porque el rodillo giratorio genera un campo alternativo óptico, magnético o eléctrico que por un receptor se convierte en una tensión alterna de una altura y frecuencia dependientes de la velocidad de rotación del rodillo, y porque el hilo parado, roto o flojo ya no impulsa al rodillo o lo hace demasiado lentamente, de modo que falte el campo alterno o muestre una frecuencia demasiado baja, y el receptor por consiguiente no emite ninguna tensión demasiado baja y porque esta diferencia en la señal de salida del receptor da origen al impulso de indicación o de maniobra.
