ABSTRACT:
The cylinder for guiding a web of textile material comprises at least one hollow space which is partly filled with a liquid heat carrier and can be evacuated. The pressure increase in the hollow space if the temperature is increased is to be limited to values below a multiple of calculated safety even though heat carriers with a steeply rising vapor pressure curve such as water are used. The solution consists in that only a quantity of heat carrier which can be evaporated completely in the volume of the hollow space already before a predetermined vapor pressure is reached, is contained in the hollow space.
