[origin: CA2970087A1] An apparatus for cleaning a felt (21, 21a, 21b) in a system for producing a paper web has a device (4, 4a) for introducing a cleaning liquid into the felt (21, 21a, 21b) and at least one following suction device (5) in the direction of movement of the felt (21, 21a, 21b) and having a vacuum duct (52), through which the cleaning liquid is suctioned out of the felt (21, 21a, 21b). The suction device (5) between the vacuum duct (52) and the felt (21, 21a, 21b) is formed with suction ducts (55, 56, 57), through which the cleaning liquid in the felt (21, 21a, 21b) is suctioned away. At least one of the suction ducts (56, 57) is assigned an inflatable valve element (58, 59). In the inflated state of the valve element the suction duct (56, 57) is closed and in its ventilated state the suction duct (56, 57) is opened.
