In pantyhose hip portion seaming operation, the open ends of a pair of stockings mounted respectively on upper and lower templates of a template unit are detected by means of phototubes to allow the both ends to be automatically positioned so that they are properly aligned. After a pair of stockings are mounted on the upper and lower templates of a template unit, a pair of phototubes arranged in upper and lower positions are moved to the ends of the stockings in such a way that upon one of the stocking ends being detected by one of the phototubes, the one phototube is caused to stop moving, the other phototube is caused to detect the presence of the other stocking. According to the condition of the other stocking as detected by the other phototube, the other stocking is moved forward or backward as required, and upon the end of the other stocking being detected by the other phototube, the hose is caused to stop moving, whereby the ends of the both stockings are properly aligned.
A method of automatically positioning stocking ends, which comprises mounting a pair of stockings on upper and lower template assemblies of a template unit and thereafter detecting the end of one of the stockings so mounted by means of one phototube A of a pair of phototubes disposed at upper and lower locations, bringing positioning plates into contact with the end of the other stocking upon said detection, causing the other phototube B to detect the presence or non-presence of the other stocking at the time of the detection of said one stocking by said one phototube A, moving the end of the other stocking, if the end is detected by said other phototube B, over a preset distance toward the front end of the template assembly, then moving said stocking end toward the base end of the template assembly and to the detecting position of the other phototube B, and conversely, if the other stocking end is not detected by said other phototube B, moving said one stocking end toward the base end of the template assembly by means of the positioning plates, and disengaging said positioning plates from the end of said other stocking at the time when the end of said other stocking is detected by said other phototube B.
An apparatus for automatically positioning the ends of a pair of stockings, comprising:
