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.

Abstract: A process of making a cut pile, tufted carpet that is non-directional is disclosed. It comprises the steps of:(a) knitting a yarn composed of thermoplastic fiber, e.g., continuous filament polypropylene ribbon, into a deknittable fabric,(b) heating the fabric to a temperature at which the curves and bends generated in the yarn by its knitted configuration are established in the yarn's memory,(c) cooling the fabric to about room temperature,(d) deknitting the cooled fabric and rewinding the yarn under enough tension to restraighten it,(e) tufting the yarn as facing yarn into a primary carpet backing material, forming a cut pile carpet,(f) coating the underside of the carpet with a heat-settable adhesive that, when cured, will help anchor the tufts of yarn in the backing material, and(g) heating the adhesive-coated carpet to a temperature at which the adhesive will set and the facing yarn will reconform to the bends and twists in its memory.

Abstract: A process of making a cut pile, tufted carpet that has the tightly curled appearance of Persian lamb is dislcosed. It comprises the steps of:(a) knitting a synthetic carpet facing yarn, e.g., a continuous filament nylon, into a deknittable fabric,(b) heating the fabric to a temperature at which the curves and bends generated in the yarn by its knitted configuration are established in the yarn's memory,(c) cooling the fabric to about room temperature,(d) deknitting the cooled fabric and rewinding the unravelled yarn under enough tension to restraighten it,(e) tufting the yarn as facing yarn into a primary carpet backing material, forming a cut pile carpet, which then can be dyed,(f) coating the underside of the carpet with a heat-settable adhesive that, when cured, will help anchor the tufts of yarn in the backing material, and(g) heating the adhesive-coated carpet to a temperature at which the adhesive will set and the facing yarn will reconform to the bends and twists in its memory.
