Abstract
A method is disclosed for reducing the formation of wrinkles on metal strip subject to cooling in continuous heat treatment lines in which the strip passes through cooling zones through which cooling gas flows. The method includes the step of gradually modifying the cooling intensity at each change in the slope of the cooling cycle.
