Atomozing air is supplied to each gun by a 3/8” O.D. polyethylen hose @, while the adhesive is delivered to the gun by a l/4” 0. D. polyethylene hose E . The AD-29 gun has a single high pressure orifice to deliver the adhesive to the subs6 rate. Atomizing air is directed to the adhesive through five air ports located in the air cap. Figure A multi-gun installation supply air and adhesive 2 - Nordson Pnu-Bond System (1 Gun) uses two manifolds (one on the air line and one on the fluid to each gun from a single suppl y source. line) to A solid-state Stitch Control will permit the spray pattern to be interrupted into a spray-gap-spray The solid-state timer is signalled by a customerpattern to keep glue consumption at a minimum. supplied triggering device (limit switch, photocell). An air control valve F permits adjustment of the atomization Cl adjusting knob is color coded to aid specific adjustment. from coarse to fine. The valve’s Adhesive flow rate is directly related to the air pressure applied to the pressure pot. The flow rate can be further refined by adjusting the needle ift. This adjustment can be’made using the screw G at the top of the gun. 0 /SSUED 1 l/2 l/75 LITHO SUPERSEDES @o/75 U.S.A. 0 Nordson CORPORATION /Amherst.
