The space between the working rollers is adjusted such that it is less than the thickness of the input material. When the workpiece is fed into the rollers as shown in Fig. 1, the deformation of the material, as the reduction in thickness, happens due to the friction generated at the interface of the material and the working rolls. Further ...
