Apparatus and method for forming coils of yarn and for heat setting the same

An apparatus for forming coils of yarn of a predetermined size and comprising:

• a supporting frame;
• a pair of feed rolls mounted to said supporting frame and arranged to feed yarn in a downward direction from a yarn source;
• a rotatable coiler tube positioned adjacent and below said pair of feed rolls, said rotatable coiler tube being vertically positioned and arranged to facilitate the travel of yarn from said feed rolls to and through said coiler tube;
• an air blowing device vertically positioned between said feed rolls and said rotatable coiler tube, said air blowing device including a guide tube having an upper portion positioned closely adjacent said feed rolls and a lower portion positioned coaxially within upper confines of said rotatable coiler tube, and an air supply duct communicating with the interior of the guide tube at a medial location along a length thereof and so that the introduced air exhausts from a lower portion of the guide tube and thereby assists in the movement and guiding of the yarn from said feed rolls to and through said rotatable coiler tube;
• a first variable speed drive connected to said pair of feed rolls and arranged to rotate said feed rolls at a predetermined speed;
• and
• a second variable speed drive connected arranged to rotated said rotatable coiler tube at a speed so as to form a plurality of loops of yarn.
