Definitions
- the invention relates to a device and a method for producing and / or treating a fibrous web, in particular paper or board web.
- curl For influencing curl (curl) of paper webs, for example, water is applied evenly over the web width by means of nozzles. It is essential that the water is applied to one side or at least in different amounts on the two sides in a bidirectional admission. Thus, the swelling change of the fibers between the top and the bottom of the web during the drying process is specifically influenced and corrected accordingly the curl behavior.
- the water can be applied via nozzles or special roller applicators.
- nozzles or special roller applicators In the case of high-quality papers in particular, attention must be paid to the best possible moisture cross-section. This is achieved by sectionally controllable nozzle dampers.
