Creping blade
摘要:
Creping blade for the detachment of a travelling paper web from a dryer cylinder, said blade having an edge or tip section engaging said cylinder and being constantly hit by the traveling web during its detachment from the cylinder. The invention resides in the improvement of said edge or tip section being provided with a wear-resistant coating on a first part of said edge section hit by the web, the other part of said edge section engaging the cylinder being uncoated or coated with a non-wear-resistant material so that said other part is subjected to sliding wear. A recess is located in the side surface so that the wear land surface that contacts the cylinder remains essentially constant throughout the operative cycle of the blade.
