Abstract:
A roll for smoothing a web comprising:a roll core having an outer surface; and a covering layer disposed on the outer surface of the roll core, the covering layer having an inner surface, an outer surface, and a radial thickness; the covering layer comprising a resilient matrix material and fillers embedded in the resilient matrix material, wherein the fillers comprise a plurality of elongated particles which have a length which is less than the radial thickness of the covering layer, wherein the plurality of elongated particles have a stiffness which is higher than a stiffness of the resilient matrix material, wherein the plurality of elongated particles are substantially radially oriented so as to provide a large number of points of increased stiffness in the covering layer, and wherein at least some of the plurality of elongated particles comprise a thermally conductive material whose thermal conductivity is higher than a thermal conductivity of the resilient matrix material.
