Abstract
A method and apparatus for obtaining packages for dying by twisting and winding processed yarns by a double twister. Between a double twisting spindle and a take-up roller disposed above, there are arranged a winding angle-adjusting device, a feed roller and a traverse device, recited from the side of the spindle. The high yarn tension on the side of the double twister is reduced by using the feed roller having a special structure to obtain a soft wound package.
