Abstract
Apparatus for calendering continuously produced articles includes a at least one calender roll and a drive having a driveshaft which is constructed in the form of a cardan shaft and operatively connected to the at least one calender roll for rotating the at least one calender roll. In order to maintain the at least one calender roll at a desired temperature, a fluid passageway means is provided for circulation of a temperature control medium. The temperature control medium is hereby introduced into the driveshaft via a rotary hollow-shaft feedthrough which is constructed for distribution of the temperature control medium. The rotary hollow-shaft feedthrough has a first fluid passageway for providing a passageway to the driveshaft, and a second fluid passageway for providing a passageway for discharge of the temperature control medium.
