ABSTRACT:
A one-piece seamless unidirectional rotary knitted anti-embolism stocking comprises a seamless tubular body integrally knitted and having varying lengths of yarn in the courses thereof resulting in a varying cross section such that the circumferential tension of the stocking decreases from the toe end to the upper end thereof. Specifically, constant cross section portions are interconnected by transition portions of gradually varying cross section in a pattern to produce on the wearer's leg a pressure which decreases substantially uniformly from the ball of the foot to the top of the stocking. Each end of the tubular body has a two-ply welt portion, and a heel patch is inlaid in the foot portion of the tubular body. The toe end of the tubular body terminates in a toe portion which is folded back on itself and seamed at the side edges of the fold. In one embodiment the toe portion is cut away along one-half the circumference and length thereof to leave a flap which is folded back and seamed to form a reduced thickness toe. Knee-high and thigh-high embodiments of the stocking are disclosed along with methods of making same on an eight-feed circular knitting machine.
