Paper web handling apparatus having improved air bar with fine scale turbulence generators

摘要

An air bar for apparatus for drying a running paper web and floatingly suspending it without contact during the drying process, which air bars are spaced along both the upper and lower surface of the web. The air bars provided by the present invention have small holes in the inclined walls which form part of the nozzle slots. These holes provide fine scale turbulence generators for air passing through the holes to the slot nozzles.
