Abstract
A slide-type bead coating apparatus in which a semi-circular groove is formed in the groove surface adjacent a moving web. The speed of the coating liquids is rapidly increased as the liquid flows drop abruptly along the falling part of the groove after which the liquids are smoothly delivered from the rising part of the groove. The maximum possible coating speed is significantly increased especially for low liquid flow rates.
