669 M-TYPE – DURKOPP ADLER
M-TYPE 669 – specialist for tubular parts. Stitching processes on tubular workpieces demand the highest requirements in terms of operator qualification and efficiency of the stitching technology. The subclasses of the M-TYPE 669 equipped with a particularly slim arm enable the most professional execution of difficult stitching processes such as assembly and binding operations, as well as decorative stitching on small leather goods and hard-to-access parts. A special feature of the 669 is its ability to bind the edge of material with low tension. For this operation, the lower transport stroke can be turned off in a few steps allowing for optimal feeding movement. The sewing equipment specially adapted for this stitching operation enables a precise binding result combined with maximum productivity and quality. Choose the machine best suited to your needs from the three equipment variants, the 669 ECO offers high functionality and flexibility – at an attractive price. The 669 CLASSIC Silverline is equipped with automatic basic functions. The 669 CLASSIC Goldline features additional functions for greater productivity and sewing comfort.
