Summary:In order to improve the prediction precision of the coating weight for the squeeze rolls with diminutive V-shaped grooves, the influence of line speed on coating weight and a model for a liquid amount transferred to strip are discussed. The influence of line speed is attributable to the viscous force occurring in the groove, and the force is estimated to be equal to that for the equivalent positive-gap in the forward roll coating with rigid rolls. The film thickness is also estimated from the published result for the forward roll coating. Our model is confirmed to be reasonable, compared with the experimental results.
