It also features high performance with low power consumption and advanced automation. It should be borne in mind that This model is not suitable for the processing of especially thin fabrics.

If you are not involved in the manufacture or alteration of clothing, you might consider household sewing machines of smaller dimensions and power.
Otherwise, keep in mind that many such models are quite expensive - mostly more than 100,000 rubles. In addition, they take up a lot of space.

For knitwear
Ploskoshovny machines intended for work with products from knitwear belong to a special class. They are also called stitching and it is with their help that they perform special flat seam - flatlock. Jack models for making such seams are most often equipped with three or four needles, can be sewn in five threads and have various devices for convenient work with knitwear and similar fabrics.

This stitch sewing machine can work with 4 and 5 threads, has a differential feed fabric and high sewing speed (6000 rpm).
The jumper model JK-8569A-02BB has three needles, you can switch to the operation mode with two of them. There is a edging function.
Chain stitch
Chain stitch sewing machines have a specialized purpose, having a fundamental difference from shuttle stitch machines. Models with one needle are needed in order to temporarily fix with one line the details of the stitched product. Then this line is quite easy to dissolve.
Other models that can sew multiple yarns successfully replace shuttle stitch sewing machines. Sewing on them is faster than on the latter, since you do not have to refill the threads in the shuttle.
A distinctive feature of stitches with a chain stitch is their elasticity, which is important when working with certain types of fabrics.

They may be needed for large sewing workshops and workshops where there is a large flow of products. They have a very complex structure: sensor systems, drive automation and many other functions. Managing them requires professional skills.

For instance, JK-804D-M2-24 works with 4 threads and allows you to perform sewing and overcasting of product edges in parallel. It runs quietly with an upgraded, economical servo motor.
The model has an improved backlight system. Very high sewing speed - 6000 stitches per minute, this characteristic is much higher than that of household overlocks of other manufacturers.
