Abstract
The invention concerns an apparatus for mechanically treating paper and includes two engraved cylinders each mounted between two support plates of the apparatus in a mutually tangential manner by means of cylindrical bearings affixed in corresponding housings fitted into the support plates, a first roller of the engraved rollers being mounted on a cradle pivoting relative to a stationary base plate on which is mounted the second engraved roller, the invention being characterized in that the cylindrical bearings are affixed in housings bounded at least in part by a detachable bracket which, when detached, frees a radial aperture through which the cylindrical bearing can be removed along a radial direction.
