Estimating the term…
A coating apparatus having a first slot between its front and center edges and a second slot between its center and back edges, wherein a coating solution is extruded continuously from each of the slots onto the surface of a flexible support running continuously along the edge surfaces of the front, center, and back edges in that order. The front edge surface has a straight-line portion on at least the terminal end portion of the front edge so that the straight-line portion extends along the direction of movement of the support and is not longer than one mm, and at least one portion of the center and back edge surfaces protrudes from the extension line of the straight-line toward the support. The coating apparatus is suitable for preparing magnetic recording media.
An apparatus for coating a flexible support moving in a downstream direction, said apparatus comprising a first slot between a front edge and a center edge downstream thereof, a second slot between said center edge and a back edge downstream thereof, a coating solution extruded continuously from each said slot onto said flexible support which passes continuously along a front edge surface on said front edge, a center edge surface on said center edge, and a back edge surface on said back edge in that order, a straight line portion on said front edge surface extending to a downstream terminal end of said front edge, said straight line portion not exceeding 1 mm in length in said downstream direction, a portion of at least one of said center surface and said back surface protruding toward said support beyond an extension line from said straight line portion, a portion of said back edge protruding toward said support beyond a tangent line to a downstream end of said center edge surface.
