Abstract: A winding device is provided with a device for the production of contact pressure of the bobbin against the drive roller. The device includes an additional pressure mechanism in the form of a pneumatic cylinder which does not reverse its torque exerted upon the bobbin holder to produce an additional contact pressure during bobbin build-up is provided.

Abstract: The instant invention relates to a winding device with a damping mechanism to prevent oscillations of the yarn body during winding. A bobbin support arm of the winding device is, for that purpose, equipped with a damping device which is made in form of an oscillating system. The oscillating system may comprise the actuating lever for the bobbin arm, for example. The oscillating weight executes oscillations in a plane perpendicular to the bobbin axis. The oscillating weight may be mounted elastically or dampingly on the bobbin arm.

Abstract: A device for the control of an open-end spinning element, including a pivoted control lever (4) is provided which is capable of assuming three different working positions. In a production position the control lever brings a first drive, running at production speed, into driving contact in the operation of the open-end spinning element. In a braking position the control lever brings a brake to act upon the spinning element. The control lever in a piecing position brings a second drive which runs at a lower speed than the first drive into driving contact with the open-end spinning element. At least the positions determining the production and the piecing position of the control lever are provided with a common control element, capable of being moved back and forth in the direction of movement of the free end of the control lever between at least two switching positions.
