ABSTRACT:
A vibration damper for use with an apparatus for applying liquid to both sides of a running web and then drying the web with an air drier. Vibrations induced by the air drier are damped by uniformly blowing air on both sides of the running web between the drier and the liquid application heads. Preferably, the gas ejection surfaces are stepped or tapered so allow larger vibration near the drier but to reduce the allowed vibration nearer the liquid application heads.
