The basic structures and theories of such machine are basically the same as those of the MY-F8007. But, the sewing platform is condensed and redesign has been made to the looper mechanism, the feeding mechanism, the feed lifting mechanism, the needle guard mechanism. As a result, the machine is compacted, reasonable, simple and convenient. In the small spatial range, the ultra-speed rotation can be realized. The stitches are stable and the rotation speed can reach 6000 R.P.M. They are more suitable for the circumferential sewing. After being equipped with accessories, they can be added with other materials to make the synchronous sewing. The change and derivation of assemblies of needle positions can form a new series of machine types. Consequently, the two-needle three-thread, three-needle four-thread interlock stitches and the two-needle four-thread, three-needle five-thread cover stitches can be formed.
