Device for treating paper webs or plies, comprising a couple of overlapped rolls (2,3) for compressing a paper web or ply passing between them. Each of said rolls (2,3) features a fixed central shaft (20,300) supported by a corresponding holder (10,83) at its ends, on which shaft a tubular jacket is fitted, with the interposition of low-friction connecting members (21,310) which are positioned on opposite sides with respect to the center line of the fixed central shaft axis, so that said tubular jacket, which is destined to come into contact with the paper webs or plies to be treated, is free to rotate about its longitudinal axis. |
