encloses a chamber 22 that has a charging opening 24, which can be closed by a
roll-up door 23, and an unloading opening 26, which can also be closed off by a
roll-up door 25.
The atmosphere in the chamber 22 can be adjusted with respect to temperature
and humidity to specified values. A heater 27 is provided for adjusting the temperature.
The heater 27 uses the heating agent returned by the return pipe 10 from the heated
rollers 8, 9 and is formed as a bypass pipeline that extends through the chamber 22. A
valve 29 is provided for adjusting the amount of heating agent from return pipe 10
passing through the chamber 22. By means of control equipment, the valve 29 can be
controlled in a manner not shown as a function of the temperature existing in the
chamber 22. The heating equipment 27 also has a fan 30 which forcibly blows air over
the bypass pipeline to provide a uniform distribution of the heated air in the chamber 22
to essentially uniformly expose all sides of a roll to the heated air. Moreover, an air
humidifier 31 is provided through which the air coming from the fan 30 passes. The
relative humidity in the chamber 22 can be adjusted by means of the air humidifier 31.
The treatment station 5 is also provided with a housing 32, which is shown
diagrammatically. This housing 32 has an inlet opening 33 and an outlet 34 for the
sheet material 3. Diagrammatically-shown guide rollers are disposed so that the sheet
