Abstract

Un metodo per il rilevamento dello stato di un filo quale lo stato di movimento la variazione di titolo o la presenza di corpi estranei trascinati dal filo stesso, detto filo essendo alimentato ad una macchina tessile comprende il rilevare la variazione della forma e/o della posizione relativa del filo rispetto ad un sensore ottico davanti al quale tale filo è atto a scorrere durante la sua alimentazione alla macchina suddetta ed, in funzione di tale variazione di posizione e/o di forma, il generare un segnale elettrico atto ad essere utilizzato per azionare un indicatore dello stato di avanzamento del filo, un circuito di controllo della macchina o organo similare. Il metodo suddetto viene attuato attraverso almeno un sensore ottico generante, su almeno una uscita, un segnale elettrico variabile in funzione della variazione della forma e/o della posizione relativa del filo rispetto al sensore, detto segnale essendo confrontato con un segnale di riferimento al fine di pilotare mezzi interruttori per consentire la generazione di un segnale elettrico d'uscita atto ad essere utilizzato da un mezzo indicatore dello stato di avanzamento del filo e/o un circuito di controllo della macchina o organo similare.
