Apparatus is provided for the simultaneous application of a plurality of layers of liquid coating compounds to an article. The apparatus and method of use thereof is, in one aspect, intended for coating a film with photographic emulsions. The apparatus according to the invention comprises: a pair of slides that extend downwardly from spaced-apart locations to define a closely space slot between their lower ends; means for supplying a layer of liquid onto each slide at the upper and whereby each ?ayer may flow down its slide through the slot, the layers being combined at the slot; and means for conveying articles to be coated beneath the slot. More than two slides may be provided, on pair of slides supplying the layer for one slide of another pair, thus allowing a large number of layers to be applied simultaneously. |
