Mills with three rolls for bending sheets are widely used in the manufacture of large diameter welded pipes, tanks and other long cylindrical products. Flat edges remain on the product after bending. The edges bending to the curvature product radius can be done with longitudinal rolling on special machines. For these machines designing a methodology for calculating process power parameters the must exists. The proposed technique is based on the bending model in dies with taking into account the influence of the non-contact deformation zone during sheet rolling. As a result, simple analytical dependencies for the vertical force engineering calculation, the rolling moment and the non-contact deformation zone were obtained. The possibility verification of their application showed good convergence of the calculated and experimental data.
