Abstract

A novel preferably poppet-valve-controlled fluid appli­ cator for extruding hot melt and other coating fluids and the like as fibers or filaments and/or droplets upon moving webs and other surfaces wherein the valve stem tip (T) blocks or per­ mits the flow of the fluid into a hollow nozzle insert (4) com­ municating with, preferably, a needle-like nozzle tube spray extruder (15), with provision for adjustment to produce controlled fiber and/or droplet spray coatings, and preferably though optionally with air-shaping control of the coatings.
