The resistance wire is wound around a very thin fibreglass core. It is then laid out on a sheet of fibreglass-rein-forced silicone cloth and usually arranged in a symmetrical pattern. If desired, the spaces between the wire runs can be made smaller in some sections of the element in order to achieve a higher output in those areas. Next, a silicone cloth is put on top and the complete element is placed in a vacuum chamber, where all air is removed from it. Lastly, the element is vulcanized under pressure and a high temperature.
