Abstract: Roll and process of manufacturing roll for the smoothing of paper webs, which has a hard roll core including in particular metal. The roll core is provided at its outside with an elastic covering layer which includes an elastic matrix material and fibers embedded into the matrix material. The diameter of the fibers is less than about 800 nm so that the surface of the elastic covering layer has an extremely high smoothness, in particular an Ra value of less than around about 0.6 mm. The thickness of the elastic covering layer amounts to between about 3 and about 20 mm. In addition to the fibers, powdery fillers are embedded in the matrix material whose outer dimensions are each less than about 1 nullm at least in one direction.
