Abstract: The invention relates to a method of manufacturing, by continuous unidirectional rotary knitting, of one-piece bifurcated lower body garments, of the type having a pair of legs, such as tights, leotards, panty hose, body stockings and the like, and of the legless type, such as briefs, panties, panty girdles, batching suits and the like. The invention provides a one-piece rotary knit garment having an elasticated waistband which is formed during the knitting of the garment, and comprises an integral part thereof. By reason of this invention, it no longer is necessary to sew or affix a separate waistband to the garment following its knitting and removal from the knitting machine. The waist opening of the garment preferably also is formed while the garment is being rotary knitted on the machine, although the invention contemplates that the waist opening may be formed subsequent to the removal of the garment from the machine.
