This allows the flat areas associated with pre-bending to be small and consistent. The centerline of the forming roll is close to that of the pinch roll. This leads to a long service life, consistent parts, and low maintenance. There are no load-bearing wear points or torsional stresses affecting roll parallelism and accuracy. Our rectilinear guide system transmits the forming roll forces directly to the hydraulic cylinder, into the machine frame, and into the foundation. The position of the rolls is controlled by the hydraulic cylinder with no additional moving parts. The Rectilinear Guide concept consists of forming rolls that are guided in place by a machined surface, and bearing blocks mounted directly above the hydraulic cylinder.
