摘要： 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.

摘要： A roll for smoothing a web, a process for making the roll and a process of repairing the roll. The roll includes a roll core having an outer surface. A covering layer is disposed on the outer surface of the roll core. The covering layer has an inner surface and an outer surface. The covering layer includes an elastic matrix material. The elastic matrix material includes a mixture of at least one thermosetting plastic and at least one thermoplastic. The process of making includes providing a roll core having an outer surface, forming an elastic covering layer including at least one thermosetting plastic and at least one thermoplastic, and applying the covering layer to the outer surface of the roll core. The process of repairing includes heating an elastic covering layer made from an elastic matrix material which comprises at least one thermosetting plastic and at least one thermoplastic, and allowing any markings in a surface of the covering layer to be filled.
