Controlled by two slides. These are defined as dual feeding machines obtained by means of a combination of 2 slides and 1 separator unit with the following functions:

• the separator unit, which closes and supports the screw column
• the 1st slide, called the positioner, brings the screw to the starting position
• the 2nd slide, called the feeder, feeds the screw parallel to the rolling dies

This system prevents overlapping of rivet shanks.

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