Abstract
An anti-ballooning ring confining an orbiting yarn in spinning or twisting machinery has an inner surface divided into a convex lower annular contact zone, hugged by the descending yarn body, and a concave upper annular zone or groove diverging from the path of the yarn so as to be swept only by radially outwardly protruding fiber ends. A wick, dipping into a supply of lubricant remote from the ring, traverses a ring-supporting tube and has an exposed stretch lodged in the groove for engagement by such protruding fiber ends which pick up lubricant therefrom and carry it onto the convex contact zone.
Claims7
In a textile machine wherein a yarn orbiting about an upright axis descends within an anti-ballooning ring restricting radial excursions of the yarn,
- the combination with said ring of a supply of liquid lubricant and conduit means extending from said supply to an outlet at an inner surface of said ring, said inner surface being divided into a lower annular contact zone of convex curvature in an axial plane and a radially recessed upper zone, said outlet being disposed in said upper zone at a location set back from the path of a yarn body hugging said contact zone but swept by fiber ends protruding radially outward from said yarn body whereby lubricant picked up by said fiber ends is conveyed to said contact zone.
