Abstract (en)

To avoid a delay in the braking action when a loom is stopped, especially with a combined brake/clutch between the drive and loom main shaft, the switch action to interrupt weaving is selectively on a weft break between the supply bobbin and the wound w store in the feed system when an electrical signal is generated, or when another criterion at the program control is achieved. The other criterion at the program control is a given number of weft insertions without a break in the weaving, or continuo uninterrupted weaving for a given time span. The switch action to stop the loom is effected when the first criterion in the prog control generates an electrical signal. Or the loom stop switch is triggered exclusively on an electrical signal showing a weft break between the supply and feed points.

Abstract (de)

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Vermeiden von Bremsverzögerungen beim Auslösen einer Bremsung des Webmaschinen-Hauptantriebs nach lang anhaltendem, ununterbrochenem Weben zu schaffen, und infolge der Bremsung Anlaufstellen im Gewebe zu vermeiden. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Webprozess wahlweise durch einen Schussfadenbruch oder ein dem Schussbruch adäquates Ereignis in dem Schussfadenzuführsystem zwischen der Vorratsspule und einem Vorspuler einer Webmaschine oder durch Erreichen eines anderen, der Webmaschinen-Programmsteuerung vorgegebenen Kriteriums, unterbrochen wird.
