Over the surface of the backing element (2) there are a plurality of sockets (5) for receiving fibres (10) fixed to the backing element by a sewing thread (11). One or a plurality of strip-like zones inclined diagonally with respect to the rectangular shape of the backing element (2) is or are provided with fibres (10) of a greater length such that when the backing element (2) is curved into its cylindrical configuration the strip-like zones with longer fibres form a helix over the surface of the roller thus formed.

Abstract: The present invention is directed toward a controller for controlling the local diameters of a temperature sensitive calender roll by selectively heating sections of a sheet of calenderable material with infrared lamps while the sheet is in contact with the calender roll or before the sheet contacts the roll. The calender roll is made of a material having at least one dimension which responds to changes in temperature. Therefore, thermal expansion of the roll, resulting from contact of the heated sheet with the roll surface, corrects local non-uniformities in the calender roll diameters. If the calender rolls unexpectedly stop or slow down so that the sheet of calenderable material becomes overexposed to infrared radiation, a fire detecting device detects and extinguishes the fire by turning off the infrared heating lamps and flooding the area around the lamps with a fire-extinguishing fluid.
