Abstract
Pressure roller with a non-rotatably mounted axial support about which a roller shell can rotate which is supported in a supporting plane on the support by hydrostatic supporting elements and is mounted to be rotatable and is guided axially and also radially at both ends by means of a guide ring arranged at each roller shell edge, the said guide ring being non-rotatable relatively to the support but capable of displacement axially and along the supporting plane; for holding the guide rings in a desired axial position relatively to the support there is situated at each end of the roller shell a device, at the side of the guide ring, the said device elastically pressing the guide ring in the axial direction towards the respective adjacent edge of the roller shell.
