ABSTRACT:
A workpiece holder for sewing the tip areas of neckties comprises a lower plate and a central folding device between which a lining cut and a necktie material cut are arranged. The center folding device has folding plates which can be displaced transversely with respect to the longitudinal direction and which, when moving together, draw in the material fullness in the necktie cut and gather it in a central fold. Lateral seams are sewn after the sewing of outer seams in the tip area of the cuts. In order to achieve a parallel retraction of the outer seams on the finished necktie, there is arranged between the lower plate and center folding device a longitudinal displacing device which comprises a clamping plate for clamping the lining cut on the lower plate and a longitudinal sliding plate which is displaceable towards the lower plate and by means of which, following the sewing of the outer seams, the material fullness of the necktie cut gathered in the central fold is drawn out in such a manner that the outer seams undergo parallel retraction.
