Jack S7-91T Heavy Duty Single Needle Post Bed Triple Feed Lockstitch Industrial Sewing Machine with Complete Fully Assembled Tabling Included

Complete Package: Machine Comes with Table and Stand Fully Assembled

This full-function single-needle post-bed lockstitch machine is engineered specifically for heavy-duty materials including leather, vinyl, PVC, and coated fabrics. The post-bed design makes it ideal for sewing hollow, tubular, and curved articles such as caps, shoes, bags, and upholstery panels where traditional flat-bed machines cannot reach. Triple feed action combines top, bottom, and needle feed with roller feet to provide powerful material transport through even the thickest sections, while the touch screen computerized control panel offers programmable sewing operations, adjustable speeds, and bartacking capabilities. Advanced features like automatic thread trimming, foot lifting, and stepper motor presser foot lift with thick section climbing ability streamline production and ensure consistent results on challenging workpieces.
