Abstract
The disclosure relates to a continuous cleaning method for cleaning a moving fabric in a paper machine. The method uses one or more cleaning stages. In one embodiment, one cleaning stage applies steam to heat and soften contaminants on the fabric followed by the application of water, preferably superheated water, to remove the contaminants. Another cleaning stage may apply hot water, steam and/or superheated water via an encapsulated shower and evacuation chamber making it possible to clean the width of the fabric without substantial rewet.
