Jack A7-DH has voice notifications in Polish. It also has an improved design of the material transport and pressure system, which increases the thickness of the sewn material.

New Automatic thread cutting system

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

Automatic needle positioning

Electronic needle positioning sets the needle to work.

Makes the starting and ending bolt

The Jack sewing machine locks and protects the stitch against unraveling at the beginning and end of the stitch.

Automatic presser foot lift

A new, additional system for adjusting the presser foot lifting height from 0 to 13 mm. It allows you to adjust the automatic presser foot lifting height to the thickness and fluffiness of the fabrics being sewn. This makes it much easier to maneuver the fabric under the presser foot.

New electronic tooth shifting system

The Jack A7-D lockstitch machine is equipped with a new electronic transport system that allows programming the movement of the conveyor teeth , which is controlled by stepper motors. Using the system is very simple - with one button, the user selects one of four tooth movement trajectories: Standard materials - standard transport for light and medium fabrics (blouses, workwear and casual clothes, light trousers, etc.) Slippery materials - thread tightening and wrinkle prevention layers of fabric (women's clothing, pajamas, sun and rain protective clothing, etc.) Thin and soft fabrics - reducing thread tension and preventing needle breakage (sportswear, underwear, dresses, etc.) Heavy fabrics - sewing multiple layers, sewing on thickening , preventing needle breakage (coats, jackets, jeans, sweaters, etc.)

Electronic regulation of sewing density

A very accurate electronic system for adjusting the sewing density with an accuracy of 0.1 mm and a maximum length of 5 mm

A talking machine

A unique feature of Jack A4F lockstitch machines is the use of a speech synthesizer, which guarantees the provision of 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 a traditional motor. It has low friction, is quiet, has a long cycle life, is smaller and lighter. Dedicated to most sewing machines. The most important advantages are 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 the oil pan typical for machines) - a small amount of oil is located in a closed tank, which protects against contamination. This not only reduces engine oil consumption, but also ensures better lubrication of individual machine mechanisms.

Makes decorative stitches

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