"Furthermore we could solve the problem of backwater in front of the nip of the couch rolls in board machines“, says Bader. Through the usage of skapaFORM-pur, a special, for this application optimized cover, the surface could be designed in such a way that the backwater could be eliminated. Because of the much higher stability of the material, a much better lifetime could be achieved as compared to rubber. The PU-covers work perfectly where normally rubber is used in the production.

In guide rolls (in the wet section), too, rubber covers could be replaced by skapaGUIDE-brilliant, respectively skapaGUIDE-release ceramic coatings.

Therefore, the cleaning of the surface and the lifetime can be improved significantly. Thus the lifetime of the wet screen is positively influenced as well, due to the considerably improved dimensional stability.
