The quality of fly pieces is now further increased by the 1710-5. Thanks to the 1710-5 the chain of the double-chainstitch, which has previously been visible on the zipper, is at the underside of the fly piece now. This means that the chain is no longer visible at the finished trousers which guarantees a higher seam safety in addition. The precise feeding technology with separate material feed for zipper and fly piece allows the trouble-free processing of various materials. A photocell ensures the exact cutting-to-length of the zippers without waste. Owing to the easy operation even less experienced staff will achieve first-class sewing results. Performance: approx. 6.500 fly pieces/ 480 min
