Auto Cornering

After the manual release of the needle, the machine sews the number of stitches set on the display with only 1 needle and stops automatically to allow us to turn the work. It is now possible to resume sewing with the pedal, the machine will automatically lower the second needle after making the preset number of stitches with a single needle. (Optional)

Electro-Pneumatic Release

Through this new mechanism for disengaging the needles controlled by solenoid valves, the release of the needle is faster and safer even at high speeds, unlike the mechanical lever. (Optional)

Short Thread

The thread trimmer cut the thread within 3 mm, automatic stitch closure to prevent thread loosening, no need to cut the remaining thread, saving time and cost. (Optional)

Electronic Tension

The tension disc openers are regulated electronically and no longer mechanically by means of a steel cable, this allows you to adjust the times and any delays. (Optional)

Voice Guide
