Abstract (en)

The unit (1) to clean a web carrier belt (3), at a papermaking or cardboard production machine, has a rotating cleaning jet (7) and a suction shell (13) to spray the belt with a heated cleaning fluid and extract it with detached dirt from the belt. At least one additional jet (23,29) sprays a cleaning medium into the suction zone (19) and/or the suction channel (15). The jet stream from the additional jet is parallel to the inner wall of the suction shell, and is operated at intervals. The additional jets are connected to a low pressure pump, to put their cleaning medium under a pressure of 5-100 bar.
