Transfer tail winding device for tandem windups |
摘要 |
Yarn winding apparatus having a pair of windups one above the other. A pair of rotatable package supports for each windup are alternately movable into surface driven engagement with a drive roll. During winding packages contact the drive roll until full. In doffing, an empty package contacts the drive roll; the yarn breaks from the full package to engage the empty package. A guide plate is rotated in contact with the yarn to lift it from the traverse guides and direct it to a location outside the path of travel of the traverse guides where a transfer tail is wound.
