Jack A6F

Computerized Needle Feeding Lockstitch Machine


Jack A6F is a specialist automatic lockstitch machine with double transport and increased work area. The distance between the body and the needle bar is 30 cm. The double transport supports the movement of materials under the foot.

The machine is equipped with an energy-saving servo motor built into the head, which guarantees quiet and reliable operation and less electricity consumption.
A closed lubrication system (no typical oil sump) guarantees lower oil consumption, better lubrication of machine mechanisms and protects the material against dirt.

The machine also has an integrated field with LED lights and a built-in USB socket that allows you to connect external devices (eg charging a mobile phone).

Work Smarter

The Jack A6F 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 A6F is full of features not found on competitively priced machines.

Simplified Control

The Jack A6F 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 A6F 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.

Direct Drive

No complicated motors or belts to deal with; the Jack A6F comes equipped with an integrated AC servo motor. The servo motor is mated to the machine head by a proprietary coaxial shaft that reduces vibration and noise; this allows the user to perform consistent seams at any speed.

Automatic Foot Lifter

The Jack A6F features an automatic foot lifter with a variety of settings. The foot lifter can be set to automatically lift with the optical fabric sensor or simply by slightly 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.

Improved Thread Trimmer

The Jack A6F features an improved automatic thread trimmer that leaves less than 3mm of tread remaining on the finished seam. The thread trimmer function can be turned on or off depending on the sewing operation with just a simple push of a button. Once turned on, fully depress the foot pedal backward to cut the thread

Dry Head

The Jack A6F head was designed to operate dry by utilizing a special DLC (Diamond Like Carbon) coating on the needlebar. This coating allows the machine head to operate without the use of lubricating oil virtually eliminating the possibility of oil contamination on fabrics.

Oil Shield Technology

The Jack A6F “Oil Shield” technology features a redesigned oil lubrication system further reducing the possibility of oil contamination on fabrics. The oil pan has been integrated into the machine and sealed. This system combined with the dry head creates a “Semi Dry” lubricating system that eliminates oil contamination on fabrics.

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.
