Abstract
A bobbin tube clamping device for a bobbin chuck for textile bobbins comprising a tubular sleeve member for supporting the textile bobbin tube and a chuck member movable within the sleeve member in the axial direction of the bobbin chuck. The bobbin chuck contains at least three openings extending substantially in the axial direction of the lengthwise axis of the bobbin chuck. Each opening is provided with at least two guide surfaces for guiding an associated bobbin tube clamping element. The portion of the bobbin tube clamping element which is guided by the associated opening is substantially segment shaped at least at its end protruding from the bobbin chuck and the oppositely situated parallel surfaces or walls of such segment-shaped end of the bobbin tube clamping element slidingly contact the guide surface of the associated opening. Each bobbin tube clamping element following the portion thereof which slidingly contacts the guide surfaces is provided with an enlarged gliding portion extending into the interior of the tubular sleeve member and protruding past the parallel walls of the segment-shaped portion thereof.
