Claims
- 1. An apparatus for smoothing a layer of liquid coated on a support, the layer of liquid including areas of irregular thickness, the apparatus comprising:
- unifying means;
- smoothing means, said unifying means and said smoothing means being surfaces on a single bar;
- transport means for transporting the support in a first direction past said unifying means and said smoothing means;
- said unifying means for unifying the areas of irregular thickness by moving the areas of irregular thickness of the layer of liquid in a direction transverse to the first direction when the transport means transport the support past the unifying means; and
- said smoothing means for smoothing the unified coated layer when the transport means transports the support past the smoothing means.
- 2. An apparatus as claimed in claim 1 wherein the unifying means include a surface provided with recessed groove means for making the coated liquid flow generally in a direction other than the first direction.
- 3. An apparatus as claimed in claim 1, wherein the unifying means is positioned proximate to and upstream from the smoothing means.
- 4. An apparatus as claimed in claim 1, wherein the unifying means includes at least one groove means which extends in a direction lateral to the first direction for unifying the coated layer along a direction lateral to the first direction by flowing the coated layer across the support in a direction lateral to the first direction.
- 5. An apparatus as claimed in claim 4, wherein the groove means has a zig-zag configuration.
- 6. An apparatus as claimed in claim 4, wherein the groove means longitudinally extends uniformly at a right angle to the first direction.
- 7. An apparatus as claimed in claim 4, wherein said at least one groove means includes a plurality of edges forming a series of rows.
- 8. An apparatus as claimed in claim 1, wherein the bar longitudinally extends in a direction lateral to the first direction.
- 9. An apparatus as claimed in claim 1, including means for reciprocating the bar in the direction of its longitudinal extent and relative to the layer of liquid.
- 10. An apparatus for smoothing a layer of liquid coated on a support, the layer of liquid including areas of irregular thickness, the apparatus comprising:
- unifying means;
- smoothing means, said unifying means and said smoothing means being adjacent curved surfaces on a single bar;
- transport means for transporting the support in a first direction past said unifying means and said smoothing means;
- said unifying means for unifying the areas of irregular thickness by moving the areas of irregular thickness of the layer of liquid in a direction transverse to the first direction when the transport means transport the support past the unifying means; and
- said smoothing means for smoothing the unified coated layer when the transport means transports the support past the smoothing means.
- 11. An apparatus as claimed in claim 10, wherein the curved surfaces form a circular arc.
- 12. An apparatus as claimed in claim 10, including a plurality of said bars arranged in series.
