Abstract

Die Verriegelungsvorrichtung für Unterfadenspulen (3) im Spulenträger (1) erfolgt durch ein axial verschiebbares Verriegelungselement (21). Das Verriegelungselement (21) ist federbelastet und liegt in der Auswurf- und Beschickungsstellung geneigt zur Drehachse (X) des Spulenträgers (1), so dass die Spule (3) aufgesetzt bzw. entnommen werden kann. Sobald die Spule (3) in den Spulenträger (1) eingeführt ist, kippt das Verriegelungselement (21) und rastet am Spulendorn (9) ein.

Figure imgaf001
The locking device for lower thread bobbins (3) in the bobbin (1) is effected by an axially displaceable locking element (21). The locking element (21) is spring-loaded and lies in the ejection and loading position inclined to the axis of rotation (X) of the bobbin (1), so that the coil (3) can be placed or removed. As soon as the bobbin (3) is introduced into the bobbin carrier (1), the locking element (21) tilts and engages on the bobbin mandrel (9).
