Abstract

A yarn storage device has a plurality of vertically extending screw spindles spaced around a circle. The lower ends of the spindles are received in a bearing plate and are coupled to drive means for rotating each spindle about its own axis. A lap flyer is rotatable around said spindles by said drive means for applying loops of yarn around said spindles. An upwardly conically tapering drum is arranged concentrically to and within said circle such that the loops of yarn are transferred from the free upper ends of said spindles onto said drum and are pushed upwardly along the surface of the drum by subsequent loops. Yarn drawn off from the upper end of the drum has a substantially constant tension.
