Sewing machine 1-needle lockstitch machine Jack A7-DH-7

Jack A7-DH-7 is a professional sewing machine with bottom feed, designed for sewing light and medium materials. The machine is equipped with an electronic transport system (teeth movement programming system) controlled by stepper motors. and closed lubrication system It is complete and ready for immediate operation, and its automatic functions, such as thread trimmer, needle positioning, programmable start and end bartacking and automatic presser foot lift, increase comfort of use and ensure optimal working conditions. Jack A7-DH-7 also has a stepper motor that allows you to electronically determine the length of the stitch with an accuracy of 0.1 mm, and the function of programming stitch sections, which allows you to obtain effective decorative stitches. These patterns can be memorized and individually configured from the panel, and can also be used as reinforcement stitches to improve stitching strength. Jack A7-DH-7 has voice notifications in Polish. It also has an improved design of the material transport and pressure system, which increases the thickness range of the sewn material.

New Automatic thread trimming system

The new generation thread trimming system allows you to obtain a thread length of up to 3.5 mm.

Automatic needle positioning

Electronic needle positioning positions the needle to work.

Makes the start and end bartack

The Jack sewing machine locks and secures the stitch from unraveling at the beginning and end of the stitch.

Automatic presser foot lift

New, additional presser foot lift height adjustment system in the range from 0 to 13 mm. It allows you to adjust the automatic foot lift height to the thickness and fluffiness of the sewn fabrics. This makes it much easier to maneuver the fabric under the presser foot.

New electronic tooth shifting system

Jack A7-DH-7 is equipped with a new electronic transport system consisting in the possibility of programming the movement of the teeth of the transporter , which is controlled by stepper motors. The use of the system is very simple - the user selects one of the four trajectories of the teeth movement with the press of a button: Standard materials - standard transport for light and medium materials (blouses, workwear and casual clothes, light trousers, etc.) Slippery materials - tightening the thread and preventing wrinkling layers of fabric (women's clothing, pyjamas, protective clothing for sun and rain, etc.) Thin and soft fabrics - reduce thread tension and prevent needle breakage (sportswear, underwear, dresses, etc.) Heavy fabrics - sewing multiple layers, sewing on beads preventing needle breakage (coats, jackets, jeans, sweaters, etc.)

Electronic regulation of sewing density

Very accurate electronic sewing density adjustment system with an accuracy of 0.1 mm with a maximum length of 5 mm

A talking machine

The unique feature of Jack lockstitch machines is the use of a speech synthesizer that guarantees voice information in English. The messages it speaks make it much easier and more efficient to use the many functions it is equipped with.

Energy-saving AC Servo motor

Brushless, it has many advantages over traditional motor. It has low friction, is quiet, has a long life cycle, is smaller and lighter. Dedicated to most sewing machines. The most important advantage is the low energy consumption (up to 71% less) compared to standard motors, the ability to easily adjust the speed and the use of a needle positioner.

Closed lubrication circuit

This model is characterized by a closed lubrication system (without an oil pan typical for machines) - a small amount of oil is in a closed tank, which protects against dirt. This not only reduces the oil consumption of the engine, but also provides better lubrication of the individual mechanisms of the machine.

Makes decorative stitches

The lockstitch machine has been equipped with the function of programming stitch sections, thanks to which it is possible to obtain effective and reinforced patterns consisting of a backstitch stitch sewn in the front-back sequence.

Programming sewing parameters - 3 function buttons

We can easily program the sewing parameters with the convenient three buttons. Thanks to them, we can perform bartacking, add a stitch and make 1/2 of the length of the stitch.

LED lighting

The machine has modern LED lighting, which is the closest to natural light and does not strain the eyes.
