Abstract (en)

A rolling apparatus applied with magnetic force established between a main roller (11) and a presser roller (13) such that a workpiece (17) undergoes a uniform and predetermined pressure throughout the rolling process, and the magnetic force is controllable by regulating the electric direct current to the magnet. Several ways of establishing magnetic force where the main roller is non-magnetic material and the presser roller is metallic magnetic and where both rollers (11, 13) are metallic magnetic materials are disclosed.
