Abstract
Method for eliminating vibration of strip travelling continuously through zones of a heat treatment or coating line in which gas is blown onto a strip travelling continuously, particularly through devices which effect cooling by blowing gas in jets with which the lines for the continuous heat treatment or coating of metal strip are equipped, characterized in that this method consists in adjusting the pressure and/or the flow rate of the cooling gas to a value lower than the nominal value in a zone located at one edge of the strip, on one side thereof, and to a value lower than the nominal value on the opposite edge, located on the other side of the strip.
