Abstract
A roller for compressing of webs of material comprises a rotating hollow roller traversed lengthwise by a stationary crosshead. Hydraulic loading devices in the form of sealing members act on the inside circumference of the hollow roller and delimit hydrostatic bearing pockets to which hydraulic pressure fluid can be supplied. The extension of the sealing members is limited by head bolts, which make it possible to position the hollow roller relative to the crosshead during operation.
