Roll leveller

A roll leveller comprising:

• a frame having a first and a second end;
• a plurality of parallel lower rolls rotatably mounted on said frame and positioned side by side in the direction in which a material to be levelled is fed by said roll leveller, said lower rolls being adapted to be driven;
• a plurality of parallel upper rolls;
• a bracket means having third and fourth ends respectively corresponding to said first and second ends of said frame, said plurality of parallel upper rolls being rotatably mounted thereon in spaced opposed relationship to said lower rolls;
• a stop means mounted on said first end of said frame for movement toward and away from said bracket means and engaged by said third end of said bracket means;
• a connecting shaft means pivotally connected to said fourth end of said bracket means and mounted on said second end of said frame for movement toward and away from said frame so as to effect changes in spacing between said upper rolls and said lower rolls;
• a rod means connected to said bracket means adjacent said stop means and extending away from said stop means;
• and
• a piston-cylinder means, mounted on said frame and connected to said rod means, for moving said rod means and said bracket means away from said stop means by pivoting movement around the pivotal connection of said fourth end of said bracket means to said connecting shaft means.
