Abstract

Cooling jets for moving webs such as continuously annealing steel strip can be deflected to aim at the edge of the web, and thereby stabilise it as it passes between. Flutter of the web is thereby reduced. The offset is between 2° and 15°, alternatively 25-75% of the divergence angle of gas leaving the jet.
