ABSTRACT:
A roll for a foil-drawing calender or the like which is substantially solid, has a central longitudinal bore hole and has journals supported in outer bearings in a roll stand. In the longitudinal bore hole is a stationary core which is supported, at axial locations corresponding to the ends of the working width, via inner bearings in the longitudinal bore hole and is braced via a hydraulic force-exerting arrangement acting in the working plane of the roll in a direction toward the roll gap and against the inside circumference of the longitudinal bore hole. In the vicinity of the inner bearings and in the region of the outer bearings, load-relieving hydraulic force-exerting arrangements are provided which brace the core against the inside circumference of the longitudinal bore hole and act in the action plane of the roll in the direction opposed to that of the other hydraulic force-exerting arrangement.
