Part 1063110A E2006 Nordson Corporation
Description
The PatternJet gun accurately applies adhesives on high-speed labeling applications.
Available nozzles include Universal Controlled Fiberization (CF), Universal Summit,
MiniBead and slot. Figure 2 shows the key components of the PatternJet module parts
family.
Theory of Operation
Adhesive is heated to application temperature, which is typically about 177 °C (350 °F), in a
melter. The melter pumps the adhesive through a heated hose to the gun. The gun then
dispenses the adhesive through dispensing modules onto a product. The type of nozzle
used on the modules determines the type of adhesive pattern produced.
The gun requires two air supplies: one to actuate the modules (module-actuating air) and
one to supply the air that shapes or fiberizes the adhesive exiting the modules (pattern air).
The module-actuating air is controlled through solenoid valves that are installed on the gun
and connected to a module-actuating air supply line with an air pressure regulator. The
pattern air is usually controlled through an air pressure regulator installed in a pattern air
supply line.
The adhesive manifold and heated air manifold are heated by cartridge-type heaters. Power
is supplied to the heaters through a cordset, which is connected electrically to the hose or to
some combination of splitter and extension cables. Resistance temperature detectors
(RTDs) sense the temperature of the adhesive or air in the manifolds and relay the
temperature through the cordsets and hoses to a melter control system or to a standalone
temperature controller.
The pattern in which adhesive is dispensed onto the product is determined by:
Sthe number and spacing of the modules
Sthe choice of nozzle
Sthe distance at which the nozzle is placed above the product
Sthe production line speed
Sthe adhesive add-on weight (melter pump speed and pressure)
Sthe pattern air pressure
Sthe pattern air temperature
Sthe adhesive application temperature
Sthe type of adhesive used
Sthe viscosity of the adhesive used

Module Overview
The PatternJet gun is air-actuated (or air-open), meaning that an air supply controlled by a
solenoid valve is required to open the module. The actuating air lifts the needle-and-piston
assembly inside the module, thus opening the module and allowing adhesive to flow
through the nozzle onto the product. Modules are also air-closed. In air-open, air-close
(AOAC) modules, the actuating air (rather than a spring) returns the needle-and-piston
assembly to the closed position.
A separate air supply is used to supply pattern air to the module; this air enters the pattern
air inlet and is directed onto the adhesive exiting the nozzle, creating the desired spray
pattern.
Figure 3 shows the flow of adhesive and air through a PatternJet module.

CAUTION: Risk of equipment damage. Do not use nonconductive pipe
compound or tape on hose fittings.
CAUTION: Improper routing and venting of hoses could result in overheating,
damage, and poor adhesive flow. To ensure proper operation, do not bundle or
tie-wrap hoses, do not bend hoses at sharp angles, and do not allow hoses to lay
on concrete floors or other cool surfaces that could conduct heat away from the
hoses.
3. Route the hose to the melter and connect it to the melter hydraulically and electrically as
directed in the melter manual.
