Felt Tip/Flow Brush automated primer system
dispenses single-part and two-part primers onto
multiple substrates to clean and prime components
prior to adhesive application.
Felt Tip/Flow Brush Dispensing System
The Nordson Felt Tip/Flow Brush primer system robotically applies
solvents, cleaners and primers to a variety of substrates. The
system can be configured for single stage applications or two
stage applications involving clear and black primers for glass
bonding. Other applications include dispensing cleaning agents
onto plastic and metal components to clean the substrate prior
to application of the adhesive, for optimal adhesion and long-term
durability.
The standard Felt Tip/Flow Brush system consists of a bulk
delivery system, one or two applicator tool with a pneumatic
valve pack and system controller.
How It Works
Either a felt tip or a brush is attached to the outlet of a fluid valve.
The felt or brush acts like an ink marker and applies the primer
or cleaner to the substrate in the specified width and thickness.
Different tips are available to change the width of the path. The
tips are manually slipped onto the outlet of the valve that has an
o-ring to ensure a leak free fit.
During down time, the tip can be stored in a fume which prevents
shop air and moisture from reacting with the primer or cleaner on
the tips to cure and harden the felt or brush.
Applicator
The applicator consists of a positive displacement metering
pump mated to a pneumatically actuated dispense valve. The
outlet of the valve is designed to accept a variety of felt tips and
brush tips using an o-ring to ensure a fluid tight seal. Positive-
displacement metering pumps mounted on the applicator, provide
accurate point of dispense control of material flow. A proximity
switch provides volume monitoring and confirms pump to air
motor integrity by monitoring pump rotation. Pump inlet
transducers monitor primer supplies, confirming sufficient
material delivery to the applicator tool. Outlet transducers prove
unobstructed material flow from metering pumps to the felt.
Metering pump solvent flush valve eliminates risk of material
curing in pump.
Features and Benefits
• Automated process removes operator interaction
with primer materials.
• Automated primer system delivers consistent
film builds and reduces primer waste, improving
quality and reducing costs.
• Bulk material supply monitors and circulates primer,
as appropriate, to ensure consistent application and
material integrity.
• A variety of felt and brush tips are available,
providing the end user flexibility to meet multiple
applications and part geometry requirements.
• Available PLC controls provide the user with
complete control over set-up, operation, adjusts
and system diagnostics.

Delivery System
Diaphragm pumps are used to deliver an uninterrupted flow
of material to the metering pumps. For material that contains
solids in suspension, like black primer, a return line can be
added to keep the material in circulation which prevents
sedimentation.
Material can be dispensed from the 5 gallon (20 liter) pail
that they are delivered in using a T-handle siphon assembly.
Pressure pumps are also available to pour the material in and
then siphon out.
Bulk material supplies are monitored with either a level sensor
or a load cell. Desiccant air dryers are used to dry the makeup
air to prevent moisture from curing sensitive materials.
Regenerative air dries are also available.
System Controller
The Felt Tip/Flow Brush primer system controller provides
operators and plant personnel with a user-friendly PLC
interface. Controller monitors and controls the function of
both the applicator tool and delivery system. Touch-screen
display provides for system set-up and adjustments, system
status and diagnostic information. Multiple part IDs can be
used to establish dispensed volume set points for a variety
of part styles.
