Abstract
Abstract A roller-type press including rollers having a roller core on which segments are secured to form a complete annulus. Each of the segments are provided at their longitudinal edges with supporting projections and recesses arranged therebetween to receive the supporting projections of adjacent segments. The segments may be fixed to the roller core by means of bolts, screws or cooled shrunk rings overlapping projections on each of the segments.
