ABSTRACT:
A method and an apparatus for sewing a waistband and applying it to a garment using a two-needle sewing machine and a blindstitch folding attachment for the waistband. A waistband is turned up to form the end of a waistband extension and is finished with a shaped seam in the region of the turnup edge. With the top sides lying one on the other, they are trimmed and then supplied by the blindstitch folding attachment to the needles spread out with the trimmed edge pointing in a feed direction. The lateral edges, turned up, are at first sewn onto the central part of the waistband while being transported backwardly. With the sewing machine stopped, a waistband beginning is clamped and extracted from a supply with the end of the waist extension moved from the folding attachment and cuffed in feed direction. Thereafter the remaining waistband length is sewn blind onto the waistband beginning under forward feed and then onto the waist edge of a pair of trousers or of a skirt, an inner covering strip being sewn in also.
The apparatus for carrying out the method comprises a turnover slide and a counter-holder for pincer-like holding of the end of the waist extension during cuffing, the counter-holder being pushed out of the end of the waist extension by the turnover slide. For feeding the waistband with the finished end of the waist extension to the needles, an auxiliary slide which is introduced into the blindstitch folding attachment is provided. A sensor system responding to the end of the waist extension serves to initiate a sequence control of the sewing machine and of the apparatus for carrying out the method.
