摘要

The method and appliance for rolling a workpiece involve roll bodies (13) in hydrostatic bearings and distributed over a surface. The surface is curved or bent in at least one direction. During rolling, only part of the roll body engages with the work-piece, while the roll bodies not engaging with the work-piece seal the hydrostatic bearing by means of a seal (32).
