A wrap-winding spinning machine for producing wrapped yarns having draw frames for attenuating slivers, wherein one wrap-winding apparatus is associated with each draw frame is proposed, with the wrap winding apparatus further including a high speed rotor and a yarn channel coaxial with the axis thereof, the rotor associated with a driven hollow spindle and a bobbin supported thereon and a balloon limiter supported on the machine frame by upstanding opposed ribs. The bobbin supports a centrally apertured cap device with the cap device having a continuously curved, convex end face with a sharply curved rim that merges with the end disc of the bobbin. The aperture in the cap device is arranged to receive the feed of the winding thread and the sliver as it passes downwardly into the yarn channel and is emitted as a finished wrapped thread.
