とによって解決しようとするものである。However, in the conventional roll coater type coating apparatus, when a foaming treatment liquid is used, the treatment liquid is supplied from the supply hose (2) to the coater pan (1) as shown in FIG. Causes turbulence in the coater pan (1), foams, and the accumulated bubbles adhere to the pickup roll (5) and are transferred to the steel strip (7) via the applicator roll (6). For this reason, there is a problem in that unevenness of processing occurs in the steel strip (7) as a product, and a chromate-treated steel sheet having a beautiful surface skin cannot be manufactured. In addition, there was a problem of precipitation of liquid components and precipitation. Accordingly, the present invention has been made in view of the above-mentioned problems, and is intended to solve the problem by improving a processing liquid supply port in order to prevent the processing liquid from foaming.

A specific description will be given together with the operation. In FIG. 1, the coating liquid passes through a supply hose (2) and passes through a nozzle header (4).
Is supplied into the coater pan (1) from a plurality of nozzles (3) attached to the pan. At that time, the flow is divided into a plurality of flows along the discharge direction of the nozzle (3) in the same direction and is rectified, so that the coating liquid does not stagnate, and even when foaming, bubbles are sequentially broken and accumulated. There is no.
