Zusammenfassung:	rolled stock production, namely hot bar rolling, possibly manufacture of fluted strip with rounded thickened portions on edges such as blanks of moving link of door hinges of automobiles. SUBSTANCE: method comprises multiple reduction of strip by thickness in horizontal grooved rolls; in last and last but one passes reducing strip with elongation degree 1.10-1.20 and 1.12- 1.25 respectively; before such procedure bending strip by angle 120-140 degrees and simultaneously reducing it by width at percentage reduction value (0.5-2.5)% in vertical rolls having grooves with reciprocal bending. EFFECT: elimination of defect formation along strip edges, enhanced operational strength of rolls, improved quality of rolled fluted strip. 4 dwg, 3 ex, 1 tbl
