New Line

With integrated control box and motor they allow a easier transport and quick machine installation.

Step Motor

The cutting and lifting of the foot are controlled by a low-vibration, low-noise stepping motor that promises high production performance with great energy savings.

Quick Response, Low Noise

We have added a double check on the operation of the motor to make it faster and more precise: first it slows down and then stops, keeping the noise below 83 decibels at 3600 rpm.

For Knitwear (K)

The rounded plate is dedicated to stretch fabrics and knitwear, the arched foot reduces the possibility of thread breakage. Suitable for swimwear and stretch with ribbing.
