发明名称 APPARATUS AND METHOD FOR FORMING ELASTIC CORESPUN YARN
摘要 <p>A spindle (20) is mounted to a frame (16) for rotation about the spindle axis. A core yarn package (61) of elastic core yarn (63) is held stationary on the spindle. Elastic core yarn (63) is withdrawn from the core yarn package (61) in a direction substantially along the spindle longitudinal axis. A nonelastic covering yarn (12) is drawn from a supply package, through the spindle (20) and along a confined yarn guide passageway (45, 46, 47) from the spindle guide passageway outwardly, upwardly and inwardly around and in spaced relation to the core yarn package for confining and guiding the covering yarn (12), and then into wrapping engagement with the withdrawn core yarn (63) to form a corespun yarn.</p>
