UNIVERSAL automatic belling machines, able to realize a 4th system, over the threetraditional mnes:

• INSIDE CALIBRATION for smoothed socket.
• BLOWING for shaped socket (sewerage type).
• “ME” MECHANICAL CALIBRATION by mandrel at expanding segments (sewerage and pressure type).
• “RS” RIEBER SYSTEM able to realize SIMULTANEOUSLY SOCKET + rubber GASKET FITTING IN (for PVC sewerage and pressure pipes).

COMPLETELY AUTOMATIC and  WITHOUT INCREASES IN COSTS, the finished product provides SEALING WARRANTY of the duct where it will be used (thus eliminating possible leakage, due to the joint absence).
A high autonomy of working is assured by the presence of a large JOINTS STOCK.
A sophisticated DIAGNOSTIC SYSTEM can reveal and signal possible working defects, including the non fitting in of the gasket, with following discharge of the pipe.
The heating is effected both inside and outside the pipe, in doublechamber oven at thermo - regulated infrared irradiation units.
A particular cooling system speeds up the working cycle.

• VERY HIGH OUTPUT.
• Safety, efficiency and functionality.
