    • PROBLEM TO BE SOLVED: To provide an extrusion coating device which can control a coating shape of the edge regardless of a coating thickness and can suppress generation of a high edge.
      SOLUTION: The extrusion coating device has coating width regulating plates 24 inserted into both edges of a slit 16, a slit die 10 for discharging a coating liquid from a discharge port 16A of the slit 16, and a chamber 26 for depressurizing the upstream side in a web running direction. The coating width regulating plate 24 is provided with a projection 24A bent toward the web downstream side and facing a web. The coating liquid is applied to the web in a state where the coating liquid is oozed on a web facing surface of the projection 24 of the coating width regulating plate 24 by the depressurization by the chamber 26.

    • 要解决的问题:提供一种可以控制边缘的涂层形状而与涂层厚度无关的挤出涂布装置,并且可以抑制高边缘的产生。 解决方案:挤出涂布装置具有插入狭缝16的两个边缘中的涂布宽度调节板24,用于从狭缝16的排出口16A排放涂布液的狭缝模10和用于将狭缝16减压的室26 上游侧处于纸幅运行方向。 涂布宽度调节板24设置有朝向幅材下游侧弯曲并面向幅材的突起24A。 通过室26的减压,将涂布液以涂布液在涂布宽度调节板24的突起24的面向卷筒纸表面上渗出的状态施加到卷材上。(C)2011 ,JPO&INPIT
