Abstract: The invention relates to a method and apparatus for washing a roll particularly in a paper-coating station, in which the roll (11) is washed with a wash sponge (12) by moving it transversely across the roll (11) as the roll (11) rotates. The movement of the wash sponge (12) takes place mechanically. The washing apparatus includes a carrier beam (15) the width of and fitted close to the roll (11) being washed, a moving cradle (21) set on this to carry the washing device (16) and to transport it once or several times from one end of the roll (11) to the other.
