Abstract:
1. An elastic roller comprising: a hard roller core; an elastic coating layer at an outer side of said hard roller core; said elastic coating layer comprising an elastic matrix material and fillers imbedded in said matrix material, wherein a thermal conductivity of said fillers is considerably higher than a thermal conductivity of said matrix material; and at least a portion of said fillers comprising metallic fillers arranged to improve thermal conductivity of said elastic coating layer such that heat is dissipated toward the hard roller core and dissipated axially by the hard roller core, wherein the elastic coating layer has a smooth surface structured and arranged for smoothing paper webs; wherein said elastic roller is formed with a length within a range of 3 to 12 m and a diameter within a range of 450 to 1500 mm and is structured to withstand compressive forces of up to 130 N/mm
