Abstract

Die Kupplungsvorrichtung (31) dient der Erzeugung eines unterstützenden Drehmoments für die Fadenwalze (13), wenn diese beim Sticken durch Zug der um die Fadenwalze (13) geschlungenen Nadelfäden in Drehung versetzt wird. Als Antrieb dient die Nadelstösselantriebswelle (41), welche mittels des Hebels (36) und des Gestänges (42) den Schwenkhebel (43) hin- und herbewegen kann. Dieser wird somit bei jedem Maschinenzyklus synchron mit den Nadelstösseln hin- und herbewegt. Ein Leerlauf sorgt dafür, dass die Kupplung (31) ein unterstützendes Drehmoment nur in einer Richtung über das Getriebe (39,40) an die Fadenwalze (13) anlegen kann. Da im Maschinenzyklus unabhängig von der Stichweite für jeden Stich immer ein gleichlanger Zyklusabschnitt zur Verfügung steht, wird durch die um die Fadenwalze (13) geschlungenen Fäden diese bei grossen Stichweiten mit grösserer Geschwindigkeit rotiert als bei kleinen Stichweiten. Die Kupplung (31) ist aber steuerbar, um die Grösse des unterstützenden Drehmoments aufgrund der in Stickprogrammen enthaltenen Daten für den jeweils auszuführenden Stich zu bemessen, so dass die Spannung in den Nadelfäden für alle Stichweiten praktisch gleich gehalten werden kann und die Gefahr von Fadenbrüchen weitgehend vermieden wird.
