Abstract

Metodo per l'infilaggio pneumatico in un ritorcitoio a doppia torsione con un fuso di torcitura a doppio perno cavo e detto metodo prevede di prelevare il tratto iniziale di filo avvolto dalla rocca di alimentazione posizionata attorno al perno cavo inferiore; di prelevare il tratto iniziale del filo avvolto dalla rocca di alimentazione posizionata attorno al perno cavo superiore per trascinarlo con iniezione di aria compressa all'uscita del cesto del fuso; di congiungere con nodo i fili delle due rocche e di afferrare l'estremità iniziale del filo della rocca di alimentazione del perno cavo superiore per trazionarla in modo che i due fili congiunti delle due rocche possono essere inoltrati al gruppo di avvolgimento per inizio ritorcitura.Method for pneumatic threading in a double twist twisting machine with a twisting spindle with a double hollow pin and said method provides for taking the initial section of wire wound by the feeding bobbin positioned around the lower hollow pin; picking up the initial section of the wire wound by the feed package positioned around the upper hollow pin to drag it with injection of compressed air to the exit of the spindle basket; to join the threads of the two cones with a knot and to grasp the initial end of the thread of the feeding cone of the upper hollow pin to pull it so that the two joined threads of the two cones can be forwarded to the winding unit for twisting start.
