  • Patent number: 4477032
    Abstract: For disturbance-free insertion of threads (49a-49d) into a winding device (2) and for simultaneously taking over the threads on the bobbin tubes (5), the threads (49a-49d) are placed, using a suction gun (74), from the eyelets (70) (thread guides) provided at the apex of the traversing triangle, onto thread guide pins (51) mounted on a shiftable rail, which for the insertion into the winding device (2) is located at the free end of the bobbin chuck. Subsequently these guide pins (51) move the threads (49a-49d), as the rail (48) is shifted back, into such a position in front of the catching means (6), that the threads (49a-49d) are taken over by stationary, but pivotably arranged thread guides (41 or 79 respectively), from the guide pins 71, and are brought jointly, using a further pivoting movement, into the catching means (6).

  • Patent number: 4068806
    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.

  • Patent number: 3970260
    Abstract: Apparatus for building a rotationally symmetrically evened bobbin package with a bobbin chuck for supporting the bobbin and with a friction drive drum for driving the bobbin. The bobbin chuck is rotatable at speeds above the critical rotational speed and there is provided on the bobbin chuck a balancing element with a mass which is freely movable along a circular path concentric with the bobbin chuck axis, which mass in the centered position of the bobbin chuck is distributable evenly and automatically along the path.

  • Patent number: 3955768
    Abstract: Apparatus for producing waste wraps and thread reserve windings on a bobbin tube which is placed onto a rotating bobbin chuck and at a face side of which there is provided a thread catching zone. For the purpose of producing the waste wraps there is provided a first lever which is arranged to be pivotable with a delay and for producing the thread reserve wraps a second pivotable lever arranged axially offset with respect to the first lever as seen from the face side. Both levers are pivotable in such a manner that they are consecutively pivoted away by the thread caught by the rotating package tube and with different delays while wraps are wound beginning at the face side with the thread tending to move along a thread guide edge towards a central position.

  • Patent number: 3934831
    Abstract: A traversing thread guide for winding a thread, comprising an elongated cam engaging portion which meshes with a helically extending endless cam groove of a traverse cylinder. A gliding member for linear to-and-fro guiding of the traversing thread guide along a rigid guide device extends parallel to the rotational axis of the traverse cylinder, said guiding member being arranged offset with respect to the center of the cam engaging portion. A thread guide member is rigidly arranged on the gliding member. The cam engaging portion comprises a base for inner radial guidance of the traversing thread guide, said base being provided with a curvature which at least approximates the curvature of the cam groove base or bottom and comprises an upper surface designed for outer radial guidance of the thread guide on an inside surface of the extended guide device.
