Patent ID: 7096704

Claim:
A cold rolling system comprising: a first rolling mill providing a first rolling reduction and comprising first non-powered turks-head rolls and first powered turks-head rolls; a second rolling mill providing a second rolling reduction which is larger than said first rolling reduction, and comprising second non-powered turks-head rolls and second powered turks-head rolls, said second rolling mill being disposed opposite said first rolling mill; means for applying a first tensile force to that part of a workpiece which passes through said first rolling mill; means for applying a first tensile force to that part of said workpiece which passes through said second rolling mill; means for applying a second tensile force to that part of said workpiece which has passed through said first rolling mill and which is to be fed to said second-rolling mill; means for applying a third tensile force to that part of said workpiece which has passed through said second rolling mill; a first straightening device disposed upstream of said first rolling mill for straightening said workpiece; means for applying a fourth tensile force to that part of said workpiece which passes through said first straightening device; a second straightening device disposed downstream of said second rolling mill for straightening said workpiece; means for applying a fourth tensile force to that part of said workpiece which passes through said second straightening device; means for applying a fifth tensile force to that part of said workpiece which is positioned between said first rolling mill and said first straightening device; a cutting device, positioned downstream of said second straightening device and running at a speed which is the same as a line speed of said workpiece, for cutting said workpiece into a desired length; and means for applying a sixth tensile force to that part of said workpiece which passes through said cutting device.
