from the rear trailing edge of housing 64 side ports 72 are provided for air adhesive conduits shown in fig4 which supply nozzles 62 0057 fig4 shows an array of 12 nozzles 62 spaced about 8 75 inches center to center generally the number of nozzles is selected to provide 200 coverage u2014 i e any given point on the web generally receives output from two nozzles as described in greater detail below each nozzle is connected to a liquid adhesive supply 63 and atomizing air supply 65 and a control air supply 67 a representative nozzle 62 is shown in fig5 the nozzle comprises a control chamber 74 which drives a shut off and clean out pin 76 to shut off or open orifice 78 adhesive is supplied from one side port 80 and air is supplied from an atomizing air port 82 on the other side of the nozzle the pressure in chamber 74 overcomes the spring bias driving pin 76 rearwardly and opening orifice 78 generally the nozzle produces a fine flat fan spray with a fairly wide spray angle thus reducing the number of nozzles needed the wider the spray angle the fewer nozzles that are required thus reducing costs and generally stabilizing and maximizing adhesive flow in any single nozzle 0059 fig6 is a diagrammatic representation of the systems that supply and control the equipment described above shower assembly 60 and supply conduit 63 are connected to adhesive reservoir 102 and supply pump 103 via supply conduit 104 which includes filter 105 and valve.
