APPAREIL A DEBRANCHER UN ENTRAINEMENT INDIVIDUEL DE BROCHE A MOTEUR ELECTRIQUE EN CAS DE PERTURBATION DE FONCTIONNEMENT DANS UNE MACHINE TEXTILE

LA PRESENTE INVENTION CONCERNE UN APPAREIL A DEBRANCHER UN ENTRAINEMENT INDIVIDUEL DE BROCHE A MOTEUR ELECTRIQUE EN CAS DE PERTURBATION DE FONCTIONNEMENT DANS UNE MACHINE TEXTILE.APPAREIL CARACTERISE EN CE QUE L'ELEMENT DE DEBRANCHEMENT 12 EST RELIE A UN DISPOSITIF 13 SERVANT A INTERROMPRE L'AMENEE DE MATIERE AU BANC D'ETIRAGE 6 QUI PRECEDE LA BROCHE 2. A textile machine such as a spinning machine has, for each spindle, a comparator which senses the voltage at a motor driving said spindle and compares it with a reference voltage. Upon the comparator sensing such a change in the motor voltage as would be consistent with breakage of the material being worked on the machine (e.g. a roving passing towards the spindle and being spun into a thread), it operates a switch which serves both to switch off the motor driving the spindle and to arrest the material passing to the spindle.
