Jack H7-C Industrial Sewing Machine for Heavy Materials
The Jack H7-C industrial sewing machine is a professional single-needle machine with top feed (walking foot), developed for reliable sewing of medium-heavy and heavy materials such as leather, bags, upholstery covers, cushions and upholstered furniture.
Thanks to its powerful integrated 750W motor, the machine easily penetrates multilayer and thick materials, while digital control ensures precision, speed and a high-quality finish.
