| 20090188643 | Creping blade - A blade for creping a paper web from a dryer surface is provided, said blade having a sliding surface facing the dryer surface during use of the blade, a web impact surface upon which the paper web impacts during creping, and a working apex formed between the sliding surface and the web impact surface, wherein the working apex is located no more than 30 percent of the total blade thickness away from a neutral fiber of the blade. Preferably, the working apex of the inventive creping blade is located at or close to the neutral fiber of the blade. A method for manufacturing the blade is also disclosed. | 07-30-2009 |
| 20090053423 | Coating Blade - Improved coating blades are disclosed, as well as processes for manufacturing such blades. The inventive blades have an intermediate edge deposit effective to reduce heat transfer from a wear resistant top deposit to the blade substrate. In one embodiment, the intermediate layer is comprised of NiCr, possibly with embedded oxide particles. Suitably, the intermediate layer and the top deposit are applied by an HVOF process. It is also envisaged that the intermediate layer may be deposited by plasma spraying. The intermediate layer may comprise stabilized zirconia. | 02-26-2009 |
