The quick change of fashion with regard to the shape of flaps or waistband extensions is no problem for the 739-23. With the help of a PC you make the new shapes for the sewing unit by yourself. For this purpose, we deliver you sets of parts for the self-manufacture of templates which can be produced easily and are equipped with an electronic chip TAGLOG. You programme this chip yourself and fix it to the template. Then, the 739-23 reads the information regarding the seam contour and executes all operations automatically. Precise edge trimming as well as the always constant seam contour and the perfectly distributed fullness are a matter of course for the 739-23. Performance: approx. 2.200-2.5000 seams/ 480 min.
