In the article results of the roll pressure dependence of the roll forming mill on the basic profile parameters are given. The pressure roll forming mill has different values with different conditions of curved profile production. It depends on the thickness of the original billet, the bend's radius and also it depends on other parameters: the width of the bendable elements, rolls' diameters, the hem's angles, the settings of the mill, the material properties, etc. It is difficult to solve such a complicated problem - taking into account the influence all factors with using the general theory of plasticity. The issue is complicated due to the influence of these factors, most of which are statistical in nature, different in magnitude and direction. It determines the pressure on the rolls as a stochastic variable.
