Work Smarter

The Jack JK-6691 was designed to improve operator efficiency and reduce fatigue. Built on the same all steel chassis as the rest of the Jack lineup and driven by the coaxial direct drive AC servo motor, the JK-6691 is full of features not found on competitively priced machines.


Simplified Control

The Jack JK-6691 control panel is simple and intuitive. From the control panel the user can adjust sewing speed, set needle position (up/down), turn on/off auto thread trimmer function, set automatic foot lifter operation, turn on/off electronic thread tension, set bartacking function or even program segmented sewing allowing the operator to repeat simple sewing tasks like sewing labels or pockets.


User Friendly

The Jack JK-6691 comes standard with integrated adjustable LED lighting, a half/full stitch button and a reverse button that can be used instead of the reverse lever. The presser foot can be raised by hand or automatically by foot pedal. On top of the machine is an integrated bobbin winder, allowing you to wind bobbins while continuously sewing.


Independent Dual Roller Feed

The Jack JK-6691 comes equipped with independent driven dual rollers ensuring smooth consistent feeding. The dual rollers prevent materials from slipping while sewing, preventing uneven seams and puckering.


Automatic Foot Lifter

The Jack JK-6691 features an automatic foot lifter with a variety of settings. The foot lifter can be set to automatically lift after trimming, lift when you stop sewing or depressing the foot pedal backwards. There are several settings that can be adjusted by the push of a button depending on the needs of the sewing operation.


Stitch in Stitch Technology

The Jack JK-6691 features proprietary "Stitch in Stitch" technology when back-tacking or bartacking. The stitch in stitch eliminates excessive puncturing of the material, feeding the needle through the same stitches when reversing over existing stitches.


Powerful Direct Drive Motor

The Jack JK-6691 comes standard with a powerful direct drive servo motor designed to tackle the most toughest of projects. This post bed machine was purpose built for use with heavy leathers, but delicate enough to handle lighter materials.


Affordable

The Jack JK-6691 comes standard with all this technology at around the same price point as our competitors mechanical models. Increase efficiency, reduce operator fatigue, increase productivity and maximize profits!


Modern Design

The Jack Sewing Machine Co. LTD, lineup of machines have all undergone design updates improving not only functionality but aesthetics. In addition to the redesigned machine head, the heavy duty table and stand have all undergone updates as well. Each machine ships as a complete set.
