2013-5-30  Basic concept of the rolling. Rolling is a process used to shape metal into a thin long layer by passing it through a gap of two rollers rotating in different directions (clockwise and anti-clockwise). The gap between the two rollers is supposed to be smaller than the thickness of the work piece of the material

a machine for the pressure shaping of metal and other materials between rotating rolls (rolling). In a broader sense, a rolling mill is an automatic system or line of machines that performs both rolling and auxiliary operations: transport of the original billet from the stock to the heating furnaces and the mill rolls, transfer of the rolled material from one groove to another, turning

Rolling Resistance an overview ScienceDirect Topics

As the tread becomes worn, tire rolling resistance decreases as the, main function of the tread is traction. Thicker and deeper treads generally have better traction on wet, snowy, or otherwise difficult road surfaces although a large amount of hysteretic material in the tread can also be a primary source of rolling resistance.
