Zusammenfassung:	FIELD: rolled stock production, possibly straightening rolled sheets in roller-type straightening machines. SUBSTANCE: method comprises steps of subjecting sheet to multiple sign-variable bending; creating common single-side curvature on sheet portion at least between second or more bending and at least between (N-2) or less bending (N - total bending number); selecting value of said curvature according to given condition. In the result sheet is oriented correctly at guiding it to straightening zone and at outlet of said zone. EFFECT: possibility of creating rational straightening mode. 2 dwg, 1 exp
