摘要：

In the literature pre-metered coating devices are described as being governed by viscous and capillary forces only, the radius of curvature of the upper meniscus being the main parameter in their operation. In this paper experimental as well as theoretical evidence is given, indicating that in the conditions prevailing in industrial applications, the liquid flow in a pre-metered coating device is mainly governed by viscous and inertial forces. The most important parameter is the contact length occurring between the liquid and support.
