Abstract
A method and device for washing a drying wire in a dryer group in a dryer section of a paper or board machine in which the drying wire is guided by drying cylinders, reversing rolls and guide rolls. A liquid jet is directed at the drying wire at a location after a first one of the drying cylinders in the dryer group and before a last one of the drying cylinders in the dryer group and/or a location on a downward run of the drying wire from one of the drying cylinders. The washing device includes a spray device for providing the liquid jet and possibly an air blow device for blowing air at the drying wire after the liquid jet in order to dry the drying wire.
