ABSTRACT:
A novel heater roller system capable of reaching temperatures in excess of 400 degrees Centigrade is used in situ to prepare highly weather resistant polymeric covering materials by compressing and fusing a layer of fibers and fiber particles by heating the layer through an overlayer of an air-impermeable, heat tolerant material such as aluminum. The fiber layer may contain reinforcing fibers, heat conductive metal flakes, and/or other additives. Such a layer is particularly useful as a roof covering material made in situ.
