Abstract

Metodo perfezionato per l'infilaggio pneumatico in un ritorcitoio con un fuso a doppio perno cavo e detto metodo prevede di prelevare il tratto iniziale di filo avvolto da una rocca posizionata nel cesto del fuso attorno al perno cavo inferiore per inoltrarlo nel perno cavo superiore accostandolo con sufficiente lunghezza al tratto iniziale di filo avvolto dipanato dalla rocca innestata attorno al perno cavo superiore e di trattenere congiuntamente i due detti tratti iniziali di filo per appoggiarli all'imbocco del perno cavo superiore, sul quale si accosta e preme con spinta una testa collegata con una sorgente di aria compressa, al fine di consentire l'infilaggio pneumatico dei fili.
