Levelling device

A device for levelling a strip of material, the device comprising:

• a plurality of extenders being motor torque transmission extenders outputting a plurality of motor torque transmission outputs;
• a first cassette frame unit having a plurality of first levelling rollers with juxtaposed axes of rotation spaced by a first pitch substantially greater than a first diameter of said first levelling rollers, each of said first levelling rollers having one extremity coupled and driven individually by one of said motor torque transmission extenders;
• at least one second cassette frame unit being interchangeable with said first cassette frame unit and having a plurality of second levelling rollers with juxtaposed axes of rotation spaced by a second pitch substantially greater than a second diameter of said second levelling rollers;
• a motor drive driving the plurality of motor torque transmission outputs for each of said extenders;
• said first diameter being greater than said second diameter;
• and
• said second cassette frame unit having at least one torque distribution module disposed and coupled between one extremity of at least one of said extenders and at least two juxtaposed extremities of said second rollers.
