摘要： 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 vibrations near the drier but to reduce the allowed vibration nearer the liquid application heads.

摘要： An extrusion-type fluid applicator having a front wall located in upstream from a rear wall relative to a moving support (substrate) on which the applicator coats a liquid through a slot between the two walls. The front wall is convexly curved toward the support. The rear wall is retreated away from the convex surface of the front wall in a direction opposite the support. The slot is tapered to decrease the width thereof toward the support.

摘要： A coating method and an extrusion-type coating head in which turbulence at the junction between two flows of coating materials is prevented to provide multi-layer simultaneous coating over a wide range of coating rates and with a good coating quality. An intermediate block is sandwiched between a rear block defining a back edge and a front block defining a doctor edge. Two coating flows pass through slits formed on either side of the intermediate block, joining at the top end of the intermediate block and flowing together into a short slot extending between the end of the intermediate block and the outlet of the head.

摘要： An application device for applying a coating liquid to a moving web which forms an applied layer of uniform thickness and with smooth surface properties. The sides of a slotted portion of an extrusion-type application head are provided with sloped or stepped portions in regions adjacent liquid-free areas of the web. This prevents scratching of the web and accumulation of extraneous matter at the edge portions of the application head.
