    Rolling Circles. The circle rolling is the main process of product forming which is divided into one feed and multi-feed process. The number of feed times depends on the process (such as the cold roll is not allowed to exceed the allowable maximum deformation rate) and the equipment constraints (such as non-slip conditions and power conditions).
