Description

Verfahren und Vorrichtung: zum Messen der.Glätte von Textilfäden Es ist Uekannt; daß für die Verarbeitung von Textilfäden im Web,- und WirleprozeB, sowie auch- in der Windeneä, Spulezeun& Zwirnerei die Glätte, also die Adhäsion eines Garnes, Beine besonders wichtige Rolle spielt. Häuf g werden zur Verminderung der Ad- häsion Präparationan, Schlichten usw. aufge- bracht; um einen- geschlossenen Faden zu erhalten. Die Güte der Verarbeitung hängt davon äby @daß der geschte@e: F#iden- fio nötige Glätte, d. h. eine -geringe Ä;dhäsäön, Tee- sitzt. Die Glätte von Textilfäden wird erfdungs.- gemäß -dadurdh gemessen, daß, man die Spitn.- nungsänderungen bestianmt,. die der Faden: durch die Reibung auf seiner ernten und glatten Oberfläche erleidet. In der Abbildung ist eine . Vorrichtung zum Messen der Faden-. glätte dargestellt. Mit a ist* ,eine Spule be- zeichnet, auf der der Fäden aufgewickelt ist.

Method and device: for measuring the smoothness of textile threads It is unknown; that for processing of textile threads in the web and wire processes, as well as - in the Windeneä, Coilzeun & Twisting the smoothness, i.e. the adhesion of a Yarn, legs play a particularly important role.
