The above-described conventional coating apparatus has the following technical problems.
Looking at the flow of the paint and the like in the dam 4, as shown by P in FIG. 5, mainly the flow of the paint and the like occurs in the upper part of the rotating roll 2 and almost no flow occurs in the upper part of the fixed roll 1. Therefore, the paint or the like staying on the upper portion of the fixed roll 1 in which no flow occurs remains for a long time, and when the residual paint or the like is replenished with the paint or the like from the discharge port 9 of the supply passage 8, For example, there is a possibility that the liquid may be mixed in the fluidized portion due to fluctuations in the liquid level, which may cause uneven coating on the support 7. The flow state of the paint or the like in the dam 4 as described above is not limited to the structure having the fixed roll 1, and occurs even in a dam type coating apparatus using a rotating roll instead of the fixed roll 1. Have been confirmed.

Further, in the dam type coating apparatus, since the viscosity of the paint or the like is relatively high, when the paint or the like is replenished from the supply passage 8, the liquid level is not immediately averaged, and as shown in FIG. ,
The liquid level Q in the axial direction of the roll varies. That is, when paint or the like is being supplied from the supply passage 8,
The liquid level near the discharge port 9 of the supply passage 8 is high, and the liquid level at a position apart from the discharge port 9 of the supply passage 8 is low. Therefore, the coating film thickness of the coating material or the like on the support 7 is thick at the high liquid level, and the coating film thickness at the low liquid level is small,
Coating streaks are generated on the support 7.

As described above, according to the present invention, the dam is divided into two by the partition plate so that the flow is generated over the entire dam, and the supply passage for the paint or the like is reciprocated to average the liquid level of the paint or the like. However, it does not matter how the support is transported or the paint or other structure is transferred to the support. Therefore, the structure for transferring the support and the structure for transferring the paint to the support are not limited to those in the above-described embodiments.

Further, according to the present invention, the dam is divided into two by a partition plate so that the flow of the paint or the like is generated over the entire dam, and the supply passage of the paint or the like is reciprocated to average the liquid level of the paint or the like. Since each of them has its own characteristics, it is not a requirement to establish the invention to provide both of them at the same time as in the illustrated embodiment, but it is possible to provide only with a structure in which only a partition plate is provided, or a paint or the like is used. It can be established only by reciprocating the supply passage.

Further, even if the paint or the like has a relatively high viscosity, there is no variation in the liquid level when the paint or the like is replenished from the supply passage, and the support is based on the variation in the liquid level in the axial direction of the roll. No coating unevenness.
