Quality standards

Darts and waistband pleats play an important role both for the fit and for the overall visual appearance of trousers, skirts and blouses. The main demand on the manufacturer is to guarantee consistent quality and economic processing on a machine that is easy to operate. The PFAFF 3586 short seam automatic sewing machine meets this requirement. The PFAFF 3586 for darts and waistband pleats is the most versatile and efficient short seam automatic sewing machine on the market. Efficiency, flexibility, performance and price are the deciding advantages of the PFAFF 3586. Within 8 hours you can sew for example 650 pairs of trousers with 4 waistband pleats and 4 darts (without basted seam). Two new versions are available with the 3586-25/01 + 3586-25/02. The new machines realize double-pointed darts up to 490 mm inside of the fabric (not on the edge), e.g. darts on the front of a shirt or darts on the back of a blouse.
