ABSTRACT:
Coating liquids are supplied to a coating hopper, and are extruded onto a slide surface of the coating hopper through slits. A pair of guide members are provided at both sides of the slide surface. Side faces of the guide members are positioned at both ends of a desired width of the coating liquids flowing of the slide surface to be applied on a traveling web. Consequently, the coating liquids that flow over the whole width of the slits are divided into the inside and the outside of the desired width by the guide members, and the divided coating liquids are extruded onto the slide surface. The coating liquids within the desired width flow down between the guide members and coat the web, whereas the coating liquids outside the desired width are collected through channels, which are formed in the guide members.
