Floating doctoring apparatus |
摘要 |
A device for doctoring and/or metering a liquid or viscous medium on a moving operating surface includes a doctoring assembly having a doctoring surface extending transversely across the entire operating surface and pressing thereagainst. A doctoring support beam movably supports the doctoring assembly in a direction transverse to the operating surface. A pressure unit produces a force which is exerted on the doctoring assembly in order to produce a contact pressure between the doctoring surface and the operating surface. Undesired temperature-based movements of the doctoring support beam relative to the operating surface can be compensated for by a compensation device located in the pressure flow path between the doctoring support beam and the doctoring assembly. This ensures that the contact pressure between the doctoring surface and the operating surface is substantially unaffected by such movements or deformations of the doctoring support beam. Thus, a compensation system for targeted counter-deformation of the doctoring support beam is not necessary.
