A coating material supply nozzle has a coating material reservoir where a coating material fed from the outside into a nozzle body, and an elongated nozzle port, from which the coating material passed through a nozzle passage is discharged. A coating material feed pipe for feeding the coating material is mounted in the coating material supply nozzle to extend in said coating material reservoir over the entire length. The coating material feed pipe is provided with at least one coating material feed bore for guiding the coating material within the coating material feed pipe into the coating material reservoir uniformly in a lengthwise direction of the coating material reservoir.

1. Field of the Invention
The present invention relates to a coating material supply nozzle capable of appropriately supplying a coating material to a traveling substrate.
1. Description of the Related Art
FIG. 1 is a partially cutaway perspective view of an embodiment of a coating material supply nozzle according to the present invention;
FIG. 2a is a sectional view taken along a line 2-2 in FIG. 1, and FIG. 2b is an enlarged sectional view of a coating material reservoir;
FIG. 3 is a partially cut away front view of the coating material supply nozzle shown in FIG. 1;
The present invention will now be described by way of an embodiment with reference to FIGS. 1 to 11.
Referring to FIG. 1, an embodiment of a coating material supply nozzle 1 according to the present invention is shown. The supply nozzle 1 includes a nozzle body 2 comprising a longer nozzle half 3 on a front side and a nozzle half 4 on a back side, which are integrally coupled to each other by a bolt 5. A side enclosure 6 is secured by bolts 7 to each of the front-side nozzle half 3 and the back-side nozzle half 4 coupled to each other. A joint surface of the front-side nozzle half 3 is formed into a flat shape, and a coating material reservoir 8 semicircular in section is defined in a joint surface of the back-side nozzle half 4 at a location intermediate in a direction of the height thereof to extend in a lengthwise direction.
In the present embodiment, the back-side nozzle half 4 is formed, so that the thickness (lateral distance) of an upper portion above the coating material reservoir 8 is slightly smaller than the thickness of a lower portion below the coating material reservoir 8. In a state in which the front-side nozzle half 3 and the back-side nozzle half 4 have been coupled to each other, a slight gap. is provided between the upper portion of the back-side nozzle half 4 and the joint surface of the front-side nozzle half 3. A longitudinally extending nozzle passage 9 is defined by the gap between the joint surface of the front-side nozzle half 3 and the upper portion of the back-side nozzle half 4 above the coating material reservoir 8, so that its lower end communicates with the coating material reservoir 8, and its upper end opens to the outside. The upper end of the nozzle passage 9 is an elongated nozzle port 10 which opens into an upper surface of the nozzle body 2.
