Abstract: Two coating supply tubes extend parallel to one another and run the full width of a moving substrate in the cross machine direction. Coating is supplied separately to each supply tube from opposite ends. The supply tubes discharge coating through spaced metering holes into an application chamber defined between a sidewall mounted to each supply tube. The counterflow arrangement of the coating supply tubes results in the fall off of coating pressure in one tube being canceled out by the increased pressure in the other tube. The fall off may be further counteracted by varying the spacing between metering holes the greater the distance from the coating inlet, by varying the diameter of the metering holes, or both. The tendency of the heated coating to cause a temperature gradient may be counteracted by cantilevering the applicator head on arms from a support beam through which a temperature-controlling fluid is circulated.
