Sewing processes on tubular workpieces make highest demands on the qualification of the operator and on the efficiency of the sewing technology. The subclasses of the new M-TYPE free arm machine 669 with particularly slim machine arm make it possible to professionally realize difficult sewing processes like assembly and binding operations as well as decorative stitching on small leather goods and difficultly accessible or tubular workpieces. A special feature of the 669 is its ability to bind the material edge with low tension. For this operation the bottom feed stroke can be deactivated by just a few steps which enables an optimum feeding movement. Sewing equipment especially adapted to this sewing operation allows a precise binding result combined with maximum productivity and quality. Choose your favourite from the three equipment variants: Due to outstanding performance parameters the 669 ECO offers high functionality and flexibility – at an attractive price. The 669 CLASSIC Silverline is equipped with automatic basic functions.
