The stepper motor controls bartack making it quieter and faster.

Step Motors

In addition to the main shaft motor, the machine has 3 other stepper motors: one on the needle bar for the needle feeding and the other two independent on the rollers to which the differential can be set. All this allows a more accurate, quick and silent sewing.

Quickly and precisely adjust the pressure of the roller using a screw located in the upper part of the machine.

Programmable Key

A button has been inserted to quickly change the stitch length.

Extendable Bartack Lever

The bartack lever is made of a double layer, so that the second part can be extracted by extending it and making it easy to use with the arm while sewing.

The large 5-inch touch screen is easy to use and allows you to change the speed, stitch length, sewing modes and other parameters in Italian.

Sewing Patterns

Thanks to the step-by-step motors it is possible to create ornamental stitches by programming different stitch lengths and stitch repetition as desired

Self-Cooling Handwheel

The structure of the handwheel works as a fan capable of keeping the internal components at about 4 degrees less than other machines, extending the life of the machine.

Folding Guide

Ensures the same distance from seams, also prevents the thread from loosening during the tight stitch, when the thickness of the fabric changes or in corner seams.

High Perforation Capacity

It can penetrate more than 110 layers of A4 paper, and the ultra-heavy fabrics of work shoes can be easily sewn.

Ultraviolet Light

In addition to the dimmable light with multiple shades and intensities, we have added ultraviolet light to increase the visibility of the drawn line of the seam.

Short Thread (X)

Precise and clean thread trimmer, thanks to its new design the thread is cut to just 3mm so you don't have to trim it by hand, saving time and money.

Bobbin End Detection

Automatic detection of the thread less than 30cm remaining in the bobbin, automatic stop for bobbin replacement, it maintains the quality of the fabric without punching it empty. (optional)
