摘要：

Bead coating geometry is used in the continuous, high‐speed coating of photographic and other films. However, bead coating suffers from instabilities occurring at maximum and minimum speeds which result in non‐uniform films and unsatisfactory coating. This article describes an experimental study of these speeds for a range of flowrates, gaps, and viscosities. Results are compared with theory.
