A reliable M-TYPE ECO cylinder arm sewing machine engineered for professional sewing of three-dimensional and tubular workpieces in technical textiles, footwear, leather goods, soft luggage and similar products. The 669 platform combines robust mechanical design with a triple feed system and economical DAC eco control to deliver consistent seam quality and dependable material handling at an attractive price point.
Cylinder arm design: Slim working arm provides excellent access for tubular, hard-to-reach and three-dimensional sewing applications.
Triple feed system: Alternating sewing feet with triple feed ensure smooth, displacement-free material transport across varied thicknesses and fabric structures.
ECO-level control: DAC eco controller offers essential functions including needle positioning and soft start, supporting efficient, repeatable operation.
Robust construction: Built for medium-heavy duty environments with strong material feed and longevity suited to continuous use.
Good cost-performance ratio: Designed to balance solid functionality with operational economy.
High sewing foot lift: Generous mechanical lift simplifies loading and unloading of bulky workpieces.
Wide application range: Ideal for assembly seams, edge binding and decorative stitching on complex or tubular components.
