ABSTRACT:
Method and apparatus for practicing the method by which the loose end of yarn, which extends between the tube notch where the yarn becomes snagged and retained and the point in or near the air doffer where the yarn becomes snapped and severed, in the manner described in the Newman et al U.S. Pat. No. 3,971,518 and in the Spaller U.S. Pat. No. 3,999,716, is trapped and wound up on a pin projecting from the outer axial end of the winder mandrel, thus preventing any possible interference of the loose yarn end with the subsequent formation of a transfer tail on the yarn package tube and/or the winding of the package portion on the yarn package tube.
