Claims

[Scope of utility model registration request]

A base body having a circular cross section, a metal plate matrix fixed to the outer surface of the base body, and a large number of uniform and fine protrusions integrally formed on the outer surface of the plate base and having a top surface and side surfaces. A metal roller characterized in that the angle between the top surface and the side surface of the projection is an acute angle, and the top surface of the projection is a flat surface along a tangent.
