Abstract

Metodo per effettuate la estrazione automatica dal passo di un filo di trama rotto in telai di tessitura ad aria. In caso di trama errata, viene inibito il taglio del filo e contemporaneamente viene alimentata nel passo una doppia trama. Il cappio da questa così formato viene convogliato, all'uscita del passo, da un flusso d'aria all'interno di un dispositivo meccanico di avvolgimento posto sul lato destro del telaio.Il dispositivo meccanico di avvolgimento comporta un condotto interno che attraversa gli organi di presa del filo di trama, nel quale scorre il flusso d'aria di convogliamento del filo di trama.Method for performing the automatic extraction from the pitch of a broken weft thread in air weaving looms. In case of wrong weft, the cutting of the wire is inhibited and at the same time a double weft is fed into the step. The loop formed by this is conveyed, at the exit of the step, by an air flow inside a mechanical winding device located on the right side of the frame. The mechanical winding device involves an internal duct that crosses the organs weft of the weft thread, in which the flow of air conveying the weft thread flows.
