Glossary 10-1Part 237478_03 2012 Nordson CorporationSection 10GlossaryAny material that can be used to adhere or “stick” one surface to another.Fine threads of adhesive caused by incomplete transfer of the adhesivemass from applicator to substrate, followed by elongation of the connectingbridges. May be caused by improper nozzle shutoff with a high viscosityadhesive.That part of the hot melt system that is used to heat adhesive to its requiredapplication temperature and pump it to the hose(s) and gun(s). It consists ofa tank or reservoir, pump, filter, distribution manifold and temperaturecontrolled heating system.An automatically actuated valve which is opened by fluid flow in one directionand closed by flow in the opposite direction.The width of an adhesive bead which has been deposited on a substrate.The measurement is taken before the bead has been flattened by adhering itto another surface.See Heater Cartridge.A non‐replaceable heating element specifically shaped to provide a uniformthermal profile in the heated object.The degradation of a fluid that occurs as a result of time and exposure toatmospheric air and/or heat.An electronic device that acts to shut down a powered AC circuit whencurrent draw (amps) exceeds some preselected value or when certain faultconditions exist.A temperature control device that closes, completing an electronic circuitupon reaching a specific temperature.The tube that connects the outlet port of a pump to the distribution manifoldof a hot melt applicator.AdhesiveAngel HairApplicatorBall Check ValveBead ThicknessCartridge HeaterCast‐in Resistive HeatingElementCharring in TankCircuit BreakerClose‐on‐rise ThermostatCrossover Tube
