Abstract:
An applicator for applying a fluid material to a traveling substrate, said applicator comprising:an applicator body positionable adjacent and transversely of the traveling substrate; said applicator body having an inlet port for receiving said fluid material, an applicator nozzle having a discharge slot facing the substrate and extending transversely with respect thereto, and a fluid distribution chamber communicating between said inlet port and said discharge slot; said fluid distribution chamber having: a first portion substantially centered at said inlet port for receipt of said fluid material therefrom and extending universally outwardly therefrom for passage of said fluid material therethrough; a peripheral fluid passage communicating with said first portion and extending therearound, said peripheral fluid passage being formed of two generally symmetrically contoured halves each having spaced ends substantially aligned with said slot and extending oppositely away from said slot alignment between said spaced ends; a second portion having a contour similar to said first portion and disposed at a spacing toward said nozzle from said first portion and communicating with said peripheral fluid passage and said slot for flow of said fluid material therethrough transversely of said slot from said peripheral fluid passage to said slot; the contour of said peripheral fluid passage providing substantially equidistant flow of said fluid material from said inlet port through said first portion and said second portion to said slot uniformly along said slot between said ends of said peripheral fluid passage halves.
