Abstract: A method for mounting pantyhose blanks which enables a pair of pantyhose blanks to be efficiently and accurately mounted on a stretch holder member of a crotch sewing machine employed in pantyhose sewing. Panty portions of a pair of pantyhose blanks are inserted on a pair of upper and lower insertion plates at a first position. At a second position, the panty portions are shifted widthwise on the respective insertion plates so that a cutting site at which the panty portions are to be cut is positioned in alignment with a center line extending across the insertion plate pair. At a third position, the panty portions are drawn so that run guard portions are set in position on the respective insertion plates; the panty portions are stretched in opposite lateral directions by a pair of pawls which act as a transfer member and are held as such before they are withdrawn from the insertion plate pair, the panty portions being then mounted on the stretch holder member of the crotch sewing machine.
