Abstract

La cimossa viene eseguita aspirando con un ugello aspirante/soffiante i codini di cimossa appena tagliati e reinserendoli nel passo riapertosi mediante inversione del flusso d'aria all'interno dell'ugello. L'ugello si posiziona a fianco del filo di trama da aspirare prima del taglio di questo, al momento della battuta, e resta in questa posizione intanto che la taglierina viene fatta avanzare fino al punto di taglio mentre il pettine retrocede dalla zona di battuta. Viene così evitato il taglio del pettine.Nei telai ad aria, dal lato di inserimento della trama, uno schermo fisso o mobile, eventualmente solidale all'ugello, devia il flusso d'aria proveniente dagli ugelli principali che disturberebbe la presa del codino di trama da parte dell'ugello aspirante/soffiante. Un intaglio a V permette l'alloggiamento del filo di trama entro lo schermo. In questo caso i mezzi di taglio possono essere fissi.Selvedge is performed by aspirating the freshly cut selvedge tails with an aspirating / blowing nozzle and reinserting them into the reopened step by reversing the air flow inside the nozzle. The nozzle is positioned next to the weft thread to be sucked before cutting it, at the moment of the stop, and remains in this position while the cutter is advanced to the cutting point while the comb withdraws from the stop area. This avoids the cutting of the comb.In the air frames, from the insertion side of the weft, a fixed or mobile screen, possibly integral with the nozzle, deflects the air flow from the main nozzles which would disturb the grip of the weft tail by the suction / blowing nozzle. A V-notch allows the weft thread to be housed within the screen. In this case the cutting means can be fixed.
