  • 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: 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.
