Sewing Machine

Features Class 3519 sews single-and two-pointed darts of high durability, due to lockstitch. The beginning of the seam can be secured with backtack or with condensed stitches. The end of the seam (darts point) is secured withe stitch condensation.Single-pointed darts are always sewn from thepocket opening to the point. This ensures a slim, neat pointwith no untidy "funneling." The required dart length and waist-point height can be programmed for every size, and there is no need to change the workholder! By means of a special keyboard, the right dart for every size can be called up directwithout any loss of time. For accurate sewing of checks and stripes the front part cuttings are positionedexactly by means of laser beam. The darts are cut open by a horizontal slitting mechanism right up to the point. The slitting system produces no cutting wsate and alows optimum off-pressing ofthe seam. Off-pressing of the dart point is also facilitaed by a fillet strip theat can be fed automatically and sewn on during the operation(optional).
