Abstract
A press roller exhibits an external interchangeable sleeve and an internal sleeve, which holds the external sleeve and which is provided with boreholes, which can be loaded with pressurized air, in order to facilitate the pulling on and off of the external sleeve. To feed the compressed air directly to the boreholes while avoiding buffer spaces that impede the pressure buildup, the boreholes are connected to compressed air lines, which are led through the interior of the internal sleeve.
