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.
Claims9
A winding machine comprising a plurality of yarn bobbins each mounted for rotation about its own fixed individual axis, a beam mounted for rotation about a fixed axis located at a substantial distance from each said bobbin axis and arranged to wind thereon an array of yarns while withdrawing said array from said bobbins through an ambient atmosphere of air, and an arrangement for reducing air resistance to the passage of the yarns by accelerating the air velocity sufficiently to substantially reduce the air resistance of the yarn run in the region surrounding said array of yarns, at least partially between the bobbins and the beam and substantially in the yarn run direction toward said beam.
