A method of curtain coating that applies a free falling curtain of liquid coating composition onto a running support is disclosed. In the method, the sides of the support parallel to the running direction of the support are bent downwardly before the curtain is applied, and thus are not coated, and are subsequently unbent.

Coating method

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.

Coating apparatus

A slide bead coating method and apparatus wherein a first coating liquid is supplied from a center portion of a slide surface and a second coating liquid is supplied along edge portions thereof contiguous to the flow of the first coating liquid. The second coating liquid has a viscosity lower than that of the first coating liquid and a flow rate which is also lower than that of the first coating liquid. In this manner, breakage of both end portions of the bead is prevented without coating both end portions thicker than the center portion while yet a high coating speed operation is attained.
