The RN series is designed to produce double-sheet ravioli with a stable, repeatable process. Independent lamination units allow dough sheet thickness to be adjusted, while the piston dosing system ensures accurate filling distribution. Stainless steel construction and magnetic safety interlocks provide hygiene, safety and fast cleaning.
The machine is complete with a lobe pump filling PLB loading unit on wheels, with independent drive; filling loading speed is controlled by inverter.

Moulds for double-sheet ravioli machine — RN 540
The forming, cutting and counter-roller cylinders are manufactured in large dimensions. The mould support (mould backplate) is made of stainless steel and fitted with wheels; the mould side plates are made of aluminium.
The forming and cutting cylinders are adjustable, manufactured in aluminium and bronze, and supported by bearings positioned on the mould side plates.
The filling distribution assembly is made of stainless steel or Brall, complete with pistons and adjustment screws to set the filling quantity for each piston, where this system can be applied.
Scrap cutting unit
Comprises the cutting unit and a modular plastic conveyor belt. It is driven by inverter and controlled via the operator panel. The unit performs both transverse and longitudinal cutting, optimising scrap recycling back to the sheeter or continuous mixer.
