Coupling between out-of-plane displacement and lateral stability of webs in air-support ovens
(Oklahoma State University, 1995-06)
In drying ovens where the web zig-zags over and under air-support bars, the web sometimes drifts to one side or the other until it runs into the oven wall. This divergence is shown to be coupled to out-of-plane displacements ...
Ground-effect theory and its application to air flotation devices
(Oklahoma State University, 1995-06)
The ground-effect theories, originally developed for air cushion vehicles (or ground-effect machines), are re-examined and compared with the air bar test results. The geometries of the tested air bars are different from ...
Resiliency of an air-floated web
(Oklahoma State University, 1999-06)
Air-flotation ovens are used for non-contact drying of coated web materials such as photographic film, magnetic media, and paper. In a typical air-flotation oven, the air bars are arranged in such a way that the path of ...
Web flutter at circular-tube air-turn bars
(Oklahoma State University, 1997-06)
Circular tubes having air-emitting holes are often used for non-contact handling of photographic and magnetic media and for printed paper webs. One of the problems of circular-tube air-turn bars is their tendency to cause ...
