Abstract: This apparatus automatically relocates the stocking toe part correctly on a setting frame prior to steam setting when the toe part is misplaced. The apparatus essentially comprises a pair of relocating members and a seam locator: the relocating members hold the stocking toe part together with a setting frame from both sides; the seam locator, essentially composed of a number of electrodes and a sheet of piezoelectric conductive rubber, locates a misplaced seam line by its protrusion on the setting frame and causes the relocating members to slip the seam line transversally to a certain extent on the setting frame so as to correct its position. Thus the magnitude of slip is determined by the relative position of the seam line and by one of the electrodes which has sensed the protrusion of the seam line so that the apparatus may automatically relocate the stocking toe part correctly on the setting frame.
