The roll drives in press sections consume remarkable amounts of energy, and also the soft roll covers on roll bodies greatly influence energy consumption. The rolling resistance of a roll cover is what affects the drive power consumption. In the PressPolar roll cover, due to the new polyurethane material, the rolling resistance is remarkably lower than that in conventional rubber and polyurethane roll covers. In addition, a roll with a PressPolar cover needs no internal water cooling. These features provide significantly reduced energy consumption.
