Differential feeding needle distance is accurate, the upper roller, the lower roller and the swing needle are driven by independent stepper motor, and the differential feeding of the upper and lower rollers can be set to achieve perfect sewing stitch coincidence;

The stepper motor replaces the traditional mechanical drive and electromagnet drive and controls the backseam structure to achieve the experience of light sound, silent backseam and super-fast sewing and backstitching;

Freely to switch the needle distance to solve the fast needle, inside and outside bending, thin and thick material, climbing the needle distance is consistent, stitch perfect coincidence;

The length of the thread tail is only 3mm;

Servo motor drive;

Automatic trimming,automatic footlift,automatic back stitching;

Roller press foot feed is easy to turn freely when sewing irregular products

Pattern programming sewing can be realized through programming mode;

Electronic keys are used for backstitching, and manual backstitching is added to make the operator more convenient;

computerized needle distance adjustment completely solves the problem of inconsistent needle distance in each set of the old manual adjustment needle distance
