ABSTRACT:
A method of and apparatus for the hot melt or other fluid coating and the web handling of lightweight low web-tension-supporting, non-woven and similar materials, having a novel nozzle region using entrance and exit web-supporting surfaces and positioning in order to compensate for web deflection caused by the fluid coating ejection forces that otherwise render the coatings non-uniform and destroy sharp leading and trailing edges of intermittent coatings.
