The JACK® JK-58720B-005 is a professional industrial double-needle needle-feed lockstitch machine designed for accurate, consistent parallel seaming on medium-weight fabrics and layered materials. Its synchronized needle-feed system advances the material with each stitch, helping prevent fabric slippage while maintaining precise and uniform stitch spacing.
Powered by a 750W Direct Drive servo motor with a self-cooling handwheel, the JK-58720B delivers smooth, quiet, and energy-efficient operation at speeds up to 3,000 stitches per minute. Its large-capacity bobbin system extends sewing time between bobbin changes, while the closed lubrication system helps keep oil contained and away from finished fabrics.
