Method for automatically sewing two stockings to form a pantyhose

Abstract

Automatically sewing two stockings to form a pantyhose article by putting the stockings on two corresponding flat, paired, juxtaposed shapes, moving the shapes close to each other with the stockings fitted thereon and cutting a longitudinal portion of the stockings, spreading apart the shapes with the cut stockings thereon and sewing the eges of the latter, rejoining the shapes and unloading the sewn pantyhose. In detail, the following operations are carried out: placing the elastic edge of the two stockings in a same preset position by seizing the elastic edge of the stocking which is located further away from the preset position and making it slide towards it, then seizing the elastic edge of the other stocking and making the two thus vertically lined up elastic edges simultaneously slide to the preset position; placing the upper part of the two stockings in a same preset position by accumulating such upper part as far as a datum line of the stockings reaches a preset position, then withdrawing it by a same preset extent; spreading the shapes apart through 180.degree. with the stockings partially cut lengthwise thereon and sewing the edges along two straight lengths in end-to-end relationship between them: the sewing of one length being simultaneous to that of the other.
