TIRELLI rotary capping machines are suitable for high production speeds. The bottles are directed by a star wheel to the capping station where the capping heads close the bottles. The caps are usually fed in by a mechanical sorter.

Two technologies are used to adjust the torque:

Magnetic: via two magnetic discs;
Brushless: with a servomotor which controls the speed and torque applied.

The format changeovers are fast and do not require the use of tools.
