Abstract
An object of the present invention is to provide a coating device of the roller type which reduces a waste of coating material and distributes the coating material uniformly to the roller brush.
The coating device includes a sold cylindrical body (11) being solid except an axial center hole (13), and radial holes (14) radially extended from a plurality of positions of the axial center hole (11), a roller brush (12) applied to the outer periphery of the solid cylindrical body (11), coating-material press feeding pipes (24) connected to both ends of the axial center hole (13) of the solid cylindrical body (11), and an arm part (31) for supporting the solid cylindrical body (11) at both ends of the solid cylindrical body (11). Those components are entirely supported by a turnable support mechanism (40) and a vertically movable support mechanism (50).

5. A curved-surface operable roller coating device comprising:
-
a coating pressure feed roller;
coating-material press feeding pipes for pressure feeding the interior of said coating pressure feed roller from both ends of said coating pressure feed roller;
an arm part for supporting said coating pressure feed roller at both ends of said coating pressure feed roller;
a turnable support mechanism for supporting said arm part such that said arm is rotatable in a plane parallel to a vertical surface including the axis of said coating pressure feed roller; and
a vertically movable support mechanism for supporting said arm part such that said arm part is vertically movable. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A coating method for coating an object to be coated in a manner that a roller is rolled while a coating material is pressure fed from the interior of said roller to the outer periphery thereof, in which a predetermined long area is coated from one end to the other end by said coating pressure feed roller, said coating pressure feed roller is stopped at said other end, to coat a long area adjacent to said long area, said coating pressure feed roller is moved to one of the ends of said adjacent long area, and said long area is coated again toward said other end, and said coating operations are sequentially repeated to finally coat a broad area,
wherein as a first step, an area of said broad area except an area as a maximum corresponding to a width of said coating pressure feed roller, which is located inside from said both ends of said broad area is entirely coated by said coating method, and as a second step, said coating pressure feed roller is rolled from a first long area to a final long area in said uncoated area, while discharging no coating material or a small amount of coating material.
