Abstract

Das Verfahren besteht erfindungsgemäß darin, dass dem für die Fadenflugzeit charakteristischen, in einer Datenbank der Webmaschinensteuerung gespeicherten Qualitätsparameter jedes Schussfadens ein die Sollfadenflugzeit sicherndes Soll-Druckprofil zugeordnet wird, womit auf die Ermittlung einer durchschnittlichen Schusszeit je Schussfadentyp, wie aus dem Stand der Technik bekannt, verzichtet wird.The method according to the invention is that for the thread flight time characteristic, stored in a database of loom control Quality parameters of each weft thread a target pressure profile securing the desired thread flight time which is to determine an average shot time each Weft type, as known from the prior art, is dispensed with.

Das die Schussfadenflugzeit sichernde Soll-Druckprofil wird erfindungsgemäß durch Verwendung einer Ventilstruktur (2) mit piezo-elektrischen Antrieben (5) erreicht.
