In particular, in the production of photosensitive printing plates for photographic light-sensitive materials such as photographic film and photographic paper, recording materials such as magnetic recording materials such as magnetic recording tape, and pressure-sensitive copying materials, continuously running long strip-shaped supports (hereinafter referred to as (referred to as the "web").
The present invention relates to an apparatus for applying a coating liquid such as a photographic emulsion or a magnetic agent to a surface. More specifically, the present invention relates to an apparatus that applies a thin film of coating liquid by colliding it with a traveling belt-shaped support.

The curtain coating method is a method in which a free-falling curtain made of one or more coating liquids is formed, and the curtain is collided with the object to be coated to form a coating film on the object. However, due to the demand for improved coating quality, high-precision coating is gradually required, and in recent years, it has been disclosed in Japanese Patent Publication Nos. 49-24133 and 49-35447. Attempts have also been made to apply curtain coating methods to fields that require particularly high precision, such as the production of photographic materials.

A fixed amount of the coating liquid S is fed into the cavity 4 in the slide hopper 1 via the metering pump P. The coating liquid S flows out through the slot 3 whose width is narrower than the cavity 4, flows down the sliding inclined surface 6 of the slide hopper 1 as a flowing layer 8, and flows down the tip lip of the inclined plate (hereinafter referred to as (referred to as a "rip"). In the lip 7, a free falling curtain of the coating liquid S, that is, a thin coating liquid film 9 is formed. On the other hand, a belt-shaped support 11 is running from the original roll through a pass roller 2, and a thin film-like coating liquid 9 is running.

The support guide mechanism of the present invention includes a track 12, a running body 13,
13', and these traveling bodies can be moved in the width direction of the support body by a drive mechanism (not shown) composed of, for example, an electric motor, a speed reducer, and a feed screw. That is, the edge guide 2 is moved from the traveling bodies 13, 13' which can slide on the track 12 fixedly suspended from the frame (not shown) of the coating machine.
0 and 20' are attached so as to be movable in the width direction of the web 11. That is, when the web end detector detects a change in the width of the web 11, the electric motor rotates the feed screw in the forward and reverse directions via the reducer, so that the running bodies 13 and 13' slide in the width direction on the track 12. The edge guides 20, 20' move and the coating width follows.
