Abstract: A vertically mounted high speed winding device for parallel plied textured yarns which device has a vertical friction roller driven at a constant high speed and adapted to rotate a package by surface contact. The device also includes a traversing mechanism embodying an L-shaped lever rotatably attached at its apex to a layrail which is adapted to reciprocate longitudinally of the package at a constant stroke length. One arm of the L-shaped lever carries a traverse modulating yarn guide, e.g., an eccentrically mounted rotatable disc. The other arm of the L-shaped lever is pivotably connected to a slide block slidable in a U-track which is pivotable about a horizontal axis. A cam means is provided for changing the angular position of the U-track with increasing package diameter for the production of conical ended packages.
