ABSTRACT:
A yarn delivery device with a yarn storage drum that is mounted to be driven rotatably about an approximately vertical axis. The yarn storage drum has an upper portion with a frustroconical yarn take-up region that is adjoined by an essentially cylindrical yarn storage region with a bead-free lower edge. A yarn is guided tangentially onto the yarn take-up region of the yarn storage drum by a yarn feed guide element, and is taken off from the yarn storage region tangentially by a yarn take-off guide element. The yarn take-off guide element is arranged with respect to the yarn storage region such that the yarn is taken off at least at a spacing from the lower edge of the yarn storage region that corresponds to the distance of the yarn along the vertical axis of the yarn storage drum between an entry and an exit of the yarn on the cylindrical yarn storage region.
