FLUTTER SUPPRESSION AIR FOILS |
摘要 |
FLUTTER SUPPRESSION AIR FOILS Apparatus and methods for reducing the amplitude and frequency of web-edge flutter associated with drawing web materials are provided. The apparatus includes a pair of air foils disposed proximate to a pair of opposing planar surfaces of the web. Each of the air foils includes a first convex surface facing the web and disposed in contact with air flowing on the web for producing a venturi effect which reduces at least the flutter amplitude in the open draw.
