ABSTRACT:
A heated cylindrical roll for handling and treating a running web of material has a laminated construction in which a series of thin circular rings, each in turn formed from a plurality of flat ring segments, are joined face-to-face to form a hollow cylindrical roll. The segments from which the circular rings are formed may comprise identical stampings and may be machined or otherwise formed prior to assembly to include an outer tooth pattern to provide a fluted roll surface for corrugating, apertures extending between the faces of the segments to define axial fluid supply passages in the assembled roll, radial slots to define vacuum passages in the assembled roll, and/or outer peripheral slots to define vacuum distribution slots in the surface of the assembled roll. The laminated roll is particularly adapted to utilize a novel steam supply and condensate return system.
