Abstract

An apparatus for the continuous polishing of a pressure roller in a coiling machine, comprising at least one abrasive rubbing element which extends parallel to the axis of rotation of and over the entire length of the face of the roller, the abrasive rubbing element being mounted on a longitudinal support displaceable with respect to the roller parallel to the axis of rotation of the latter, the longitudinal support being mounted to pivot about two coaxial pivots under the action of at least one pneumatic control jack to which it is pivotably connected, the jack being itself articulated on another pivot which is parallel to the two coaxial pivots, thereby to elastically apply the abrasive rubbing element against the face of the roller as the latter rotates in the coiling machine, so as to smooth the roller face and remove any asperities adhering thereto during the winding of a coil, and the longitudinal support being hollow and supplied with cooling water, the support having a pluality of orifices for projecting jets of water onto the face of the roller near the rubbing element and at least upstream of the rubbing element relative to the direction of rotation of the roller.
