  • Patent number: 5058516
    Abstract: An apparatus for automatically positioning welt portions and garter lines of pantyhose materials by aligning upper and lower positions in relation to each other for carrying out a pantyhose panty part seaming process, in which when detection sensors detect materials roughly fitted to respective upper and lower template assemblies, plates for positioning garter lines cause a panty part to move backward to be inserted deeply onto the template assemblies and the garter lines of the upper and lower materials are positioned by aligning with each other through detection sensors for positioning garter lines, and successively, a plate for positioning welt portions causes the panty part to move backward, stretching the panty part to a prescribed length so that the welt portions of the upper and lower materials are aligned with each other, thus fully fitting the upper and lower materials to the template assemblies and, at the same time completing the positioning of the welt portions and garter lines by aligning upper a
