ABSTRACT:
A yarn spindle is provided having a housing, a spindle drive shaft rotatably mounted in the housing, and a cylinder fixedly attached to the spindle drive shaft. The cylinder includes a downwardly extending circumferential skirt, with the skirt and the spindle drive shaft defining an annular space between them. The skirt has a bottom edge with at least four thread cutting slots disposed therein, the slot being a substantially rectangular notch through the thickness of the skirt. The at least four thread cutting slots are equally spaced about the bottom edge. The spindle also includes a waste thread spool statically mounted on the housing for shielding the spindle drive shaft against contact with waste yarn. The waste thread spool includes a frusto-conical barrel having a top end, a bottom end, an axial hole, and an inclined outer wall. The outer wall is angled approximately 30 to 35 degrees from the vertical and has a substantially vertical groove formed therein. The radius of the barrel increases from bottom to top, and the barrel extends upward, underneath the skirt, into the annular space between the skirt and the spindle drive shaft. The spindle further includes a drive assembly for use with a drive belt, the drive assembly being coupled to and thereby powering the spindle drive shaft.
