This will make an additional one Heat input in the outer edge area of the godet casing and in the end face generated. This additional radiant heater thus brings heat energy in the area of the godet, which is the strongest Cooling is exposed.
  • one low surface temperature of the heating coil in the range of 500 to 800 ° C is sufficient to bring the godet jacket to a temperature of approx. To heat 250 °.
  • the design of a godet according to claim 10 or 11 is especially for godets with a relatively long occupancy length of approx. Can be used from 250 to 300 mm.
  • the different in the zones of the godet The thermal energy introduced is independent of each other adjustable radiant heater generated directly.
  • By heating the Galette jacket with several radiant heaters also has the advantage that a finely graduated surface temperature can be set and a sensitive control of the surface temperature with fast Standard times are possible.
  • the zones can be the same widths or have different widths, the turns in the Heating coil with the same or different distances from each other can be arranged within a zone.
  • the Invention according to claim 3 between the adjacent radiant heaters Arrays arranged, which are attached to the carrier and for Godet jacket has an air gap of a few millimeters. Thereby there are limited heat zones depending on the respective assigned radiant heater are heated.
  • each zone a temperature sensor is arranged on the godet jacket and the respective radiant heater in a control loop depending on the measured temperature can be regulated.
  • a temperature profile of the occupancy length by means of the control device can be specified.
  • the heating coils of the radiant heaters have different heating lengths, so that their specific load can be varied.
  • a specific load of approximately 5 watts per cm 2 is achieved.
  • the godet has a jacket 1, the front on free end of the godet is firmly connected to an end wall 25. In the In the middle, the end wall 25 is concentric with the jacket 1 aligned collar 9 on.
