Sewing machine 1-needle lockstitch automatic Jack A7-D

Jack A7-D is a professional sewing machine with bottom transport, designed for sewing light and medium materials. The machine is equipped with an electronic transport system (tooth movement programming system) controlled by stepper motors. and a closed lubrication system It is complete and ready for immediate operation, and its automatic functions, such as thread cutting, needle positioning, programmable start and end bar, and automatic foot lift, increase user comfort and provide optimal working conditions. The Jack A7-D also features a stepper motor, which allows the stitch length to be set electronically with an accuracy of 0.1 mm, and a stitch section programming function for striking decorative stitches. These patterns can be memorized and individually configured from the panel, and can also be used as reinforced stitches to improve stitch strength. The Jack A7-D 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 Cutting System

The new generation thread cutting system allows for thread lengths of up to 3.5 mm.

Automatic needle positioning

Electronic needle positioning sets the needle to work.

It performs the starting and finishing bolt

The Jack sewing machine locks and protects the stitch from snagging at the beginning and end of the stitch.

Automatic foot lift

New electronic system of teeth shifting

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

Electronic sewing density adjustment

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

Talking machine

A unique feature of the Jack A4F lockstitch machine is its use of a speech synthesizer, which guarantees the provision of voice information in English. Its spoken messages make it much easier and more convenient 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 life cycle, 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 speed and the use of a needle positioner.

Closed lubrication circuit

This model features a closed lubrication circuit (without the usual oil sump) - a small amount of oil is contained in an enclosed tank, which protects it from contamination. This not only reduces the oil consumption of the engine, but also provides better lubrication of the individual mechanisms of the machine.

Performs decorative stitches

The lockstitch machine has been equipped with the function of programming stitch sections, which makes it possible to obtain striking and enhanced patterns consisting of a lockstitch sewn in a front-to-back sequence.

Programming of sewing parameters - 3 function buttons.

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

LED lighting

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