Obtained by means of 3 punches controlled by 3 slides. Combined feeding obtained by means of a combination of 3 runners with the following functions:

• the 1st slide, called the separator, separates the screw to be fed from the screw column
• the 2nd slide, called the positioner, brings the screw to the starting position
• the 3rd slide, called the feeder, feeds the screw parallel to the dies

This system prevents overlapping of long screw shanks.

Approximate values. The machine speed can change according to the material used and the type of item to be rolled. Measures in mm.
