[發明所欲解決之課題]
根據現有的連續塗佈裝置，在連續處理板寬不同的鋼板時，起因於鋼板的板寬減少，飛散塗佈液捕捉板與鋼板的寬度方向端部（邊緣部）之間的距離會增大，藉此存在使鋼板穿過的通板開口部未被完全覆蓋的情況。結果，來自鋼板或附帶輥的邊緣部的飛散塗佈液會滲入至通板開口部，藉此有可能在鋼板上產生表面缺陷，而使得成品率降低。[Problems to be Solved by the Invention]
According to the conventional continuous coating apparatus, when the steel plates having different plate widths are continuously processed, the distance between the scattered coating liquid capture plate and the widthwise end portion (edge portion) of the steel plate increases due to the decrease in the plate width of the steel plate. Thereby, there may be a case where the opening portion of the through plate through which the steel plate passes is not completely covered. As a result, the scattered coating liquid from the edge portion of the steel plate or the attached roller penetrates into the opening portion of the through plate, thereby causing surface defects in the steel plate and reducing the yield.
本發明是鑒於所述問題而完成的，其目的在於提供一種即使在鋼板的板寬發生變化的情況下，亦可抑制在鋼板上產生表面缺陷的連續塗佈裝置。

Accordingly, even when the plate width of the steel plate S is changed, it is possible to suppress the scattering of the coating liquid from the edge portion of the steel plate S or the roller with the penetration into the through-plate opening 2a, and thus it is possible to suppress the occurrence of a surface on the steel plate S defect.
再者，如圖2所示，理想的是在飛散塗佈液回收板11a、飛散塗佈液回收板11b的端部設置缺口部14a、缺口部14b，鋼板S的寬度方向兩端部穿過缺口部14a、缺口部14b內部。根據如上所述的構成，可增大飛散塗佈液回收板11a、飛散塗佈液回收板11b覆蓋通板開口部2a的面積，因此可進一步抑制來自鋼板S或附帶輥的邊緣部的飛散塗佈液滲入至通板開口部2a，從而進一步抑制在鋼板S上產生表面缺陷。Further, as shown in FIG. 2, it is desirable that notch portions 14 a and 14 b are provided at the ends of the scattered coating liquid recovery plate 11 a and the scattered coating liquid recovery plate 11 b, and both ends in the width direction of the steel plate S pass through. Inside the notch portion 14a and the notch portion 14b. According to the configuration described above, since the area of the scattered coating liquid recovery plate 11a and the scattered coating liquid recovery plate 11b covering the through-plate opening portion 2a can be increased, the scattering coating from the steel plate S or the edge portion with the roller can be further suppressed. The cloth liquid penetrates into the through-plate opening 2a, thereby further suppressing the occurrence of surface defects in the steel sheet S.
