PFAFF 3686-22/02 Darts to 250 mm

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 3686 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 3686. 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 3686-25/11 + 3686-25/12. 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.

Features

• Excellent quality; high repeating accuracy; seams and pleats with exact measurements. Only brief instructions required due to the simple and operator-friendly handling
• Darts are sewn from the pocket opening to the point. This ensures a slim, neat point with no untidy “dimples”
• The patented material take-over station assures exact seams
• Loading table for exact positioning of the workpieces and their insertion during sewing. This partially overlapping work method enables the economic use of the machine
• Conversion independent of guide rails / preprogrammed seam contours enable a change of operations in a matter of seconds
• Identical dart depths for identical material thickness; even when switching the material and thus varying material thicknesses the desired dart depth may be exactly maintained by using a “correction key”
• Upper thread monitor
• Special application: Sewing of pleats on strip curtains
• NEW: DAC COMPACT control unit

The new control panel P1

• The P1 are user friendly control panels with many service functions and different user levels
• The desired measurements may be directly entered via the P1 operator panel of the touch screen (see examples on the next pages). Predefined standard seams are quickly edited / modified with ease
• Sewing of up to 8 different seam types in any desired sequence, so e.g. different darts and waistband pleats can be set and produced mirror-imaged

• Customized seam configurations may be individually created in the teach-in mode
