Abstract
Abstract Pantyhose are formed from two circularly knitted blanks of which the toes have been left unsewn, by an operation wherein the upper portions of the blanks are slit and sewn and then, without turning the entire garment inside out, the garment is slipped over a pair of suction tubes in close proximity to the sewing machine on which the panty portion has been sewed, and suction applied to pull the toe portions through and out of the ends of the tubes in inside-out condition for sewing of the toes which then can be pulled out of the tubes by sliding the leg portions back along the tubes until the toes have been turned to their original position, and then the entire garment slid forwardly off the tubes; thus greatly expediting the operation. The blanks may be dyed and scoured at a boil in advance of these operations.
