OUR WIDE RANGE OF ACCESSORIES FOR PLASTIC TREATMENT MACHINE ALSO INCLUDES HIGHLY RELIABLE AND LONG-LIFE EXPANDING SHAFTS.

THE MANUFACTURING PROCESS ADOPTED FOR THESE SHAFTS IS EXECUTED WITH THE GREATEST CARE AND IT CAN BE CONSIDERED AS A CRAFT WORK.

THE SHAFT INSIDE IS FINISHED WITH SPECIAL CARE SO THAT THE EXPANDING TUBULAR BODY WILL NOT BE DAMAGED BY EDGES OR BURRS AND THIS MAKES OUR SHAFTS PARTICULARLY RELIABLE & DURABLE IN THE LONG RUN WITH MINIMUM MAINTENANCE.

WE HAVE DESIGNED A SPECIAL EXPANDING SYSTEM ENSURING A PERFECTLY CONSTANT INTERNAL PRESSURE WHICH AVOIDS THE PROBLEM OF ROLLS MOVING DURING TREATMENT. OUR SHAFTS ARE MANUFACTURED WITH TERMINALS ACCORDING TO CUSTOMER'S NEEDS AND THEREFORE THEY CAN BE ADAPTED TO ANY PULLING OR UNWINDING SYSTEM.

OUR SHAFTS ARE AVAILABLE IN CHROME PLATED STEEL CONSTRUCTION FOR CRITICAL APPLICATIONS REQUIRING HIGH RESISTANCE TO BENDING, OR THEY CAN BE MADE OF ALUMINIUM FOR NORMAL OPERATIONS REQUIRING GREATER HANDLING.

NORMALLY, THEY ARE EQUIPPED WITH 5 EXPANDING GRIPS WHICH CAN TRAVEL ALONG THE SHAFT ENTIRE FACE TO PERMIT WINDING OF SINGLE OR MULTIPLE ROLLS.

THE EXPANDING EFFECT IS ENSURED BY A MAIN TUBULAR BODY WHICH IS RESISTANT TO HIGH PRESSURE, VERY STOUT AND DURABLE AND WHICH BY EXPANDING AGAINST THE SHAFT SMOOTH POLISHED INTERNAL FLATS CAUSES THE EXPANDING GRIPS TO COME OUT. THE AIR INFLATION VALVE CAN BE PLACED ON ONE OF THE TWO ENDS OF THE ROLLER HOLDING THE CORES OR ON TOP OF THE TERMINALS, IT ALLOWS A QUICK DEFLATION AND IT CAN BE EASILY REPLACED, SHOULD DAMAGE OCCUR.
