The JACK® JK-H7-C is a single-needle industrial lockstitch machine designed for workshops sewing layered textiles and other demanding materials. Its walking-foot and top-and-bottom feeding arrangement helps guide fabric assemblies through the stitching area.

For upholstery, bags, canvas, vinyl, and selected leather work, the direct-drive system and electronic controls provide an industrial sewing platform. JMJ Sewing Machines supplies this unit with a table and stand, assembled and sewing-tested before delivery.

• JACK® JK-H7-C sewing machine head
• Integrated direct-drive motor system
• Industrial sewing machine table
• Heavy-duty metal stand
• Standard manufacturer-supplied accessories

Before delivery, JMJ Sewing Machines inspects the assembled machine, checks relevant mechanical and electronic functions, performs appropriate adjustments, and conducts a sewing test to assess stitch formation and material feeding.

These preventive checks help identify assembly and operating issues; they do not guarantee that defects can never occur.

Machines purchased directly at our Orlando store include a brief, complimentary explanation of the main controls and basic operation at pickup. This is not an extended training course. Shipped orders do not include in-person instruction.

For upholstery, canvas, vinyl, and selected leather projects, confirm the actual material thickness, needle, thread, and machine settings before purchase. Our team can help evaluate whether this model suits your production requirements.

JMJ Sewing Machines offers compatible needles, bobbins, hooks, presser feet, feed components, and other industrial sewing accessories, subject to compatibility and availability. We also provide diagnosis, repair, adjustments, and preventive maintenance.
