Claims28
A cleaning device to clean a roll in a paper machine comprising:
- a roll;
- a spray unit comprising a high-pressure spray device having an operational pressure of at least approximately 10 bar to spray a Surface of the roll to be cleaned with a cleaning agent;
- a rinsing unit arranged downstream of the high-pressure spray device in a rotational direction of the roll;
- and
- a scraper device located downstream of the spray unit and the rinsing unit, relative to a rotational direction of the roll, to remove the cleaning agent from the roll surface.
