Abstract
The invention relates to a winding machine, in particular a warping or beaming machine, in which yarns are drawn off a bobbin creel at high speed. To reduce the air friction of the yarns and to improve the removal of fiber contaminating material, there is provided an arrangement for accelerating the air which surrounds the yarns. In addition it is possible to provide an extractor hood with which the air is sucked out of the region of the winding unit and recirculated to the said arrangement.
