Способ изготовления симметричных профилей последовательной по переходам подгибкой элементов профиля в валках профилегибочного станка с дополнительной подгибкой полок в межклетьевом пространстве на 3-4°, отличающийся тем, что на первом переходе в средней части подгибаемой полки формуют устраняемый рифт выпуклостью наружу с постоянными радиусами сопряжения, на втором переходе производят подгибку полок со спрямлением рифта, а в межклетьевом пространстве между по крайней мере двумя из последующих переходов одновременно с дополнительной подгибкой полки производят ее поперечный изгиб выпуклостью наружу и последующее спрямление в очередном переходе в закрытом роликовом калибре, причем, высоту устраняемого рифта определяют по формулеA method of manufacturing symmetrical profiles by successive bending of profile elements in rolls of a roll forming machine with additional bending of shelves in the inter-stand space by 3-4 °, characterized in that at the first transition in the middle part of the foldable shelf, the removable rift is formed by convexity outward with constant mating radii, the second transition, the shelves are bent with straightening of the rift, and in the interstand space between at least two of the subsequent transitions simultaneously with additional podgibkoy shelves produce its transverse bending outwardly convex and subsequent straightening in the next transition in the closed roller caliber, and, Rift eliminates height determined by the formula
