This machine is able to achieve high quality sewing even at its highest speed of 4,200 rpm.
With the adoption of new-type thread trimming mechanism, it is no longer required to snip off the end of thread.
The feeding and needle bar mechanisms are driven by a stepping-motor capable of analyzing as precise as 0.05mm, which ensures beautiful and quality seam.
By setting the sewing speed of the first 5 stitches on the control panel, the machine starts working at low speed, which can largely prevent thread breakage and fraying at the beginning of sewing.
Bartacking can be activated through electronic operation, preventing unthreading of the thread that is likely to occur at the end of sewing.
Wide range of application:
Suitable for buttonholing on shirts, work uniforms etc.
