INSTALLATION DESCRIPTION

ELECTRICAL REQUIREMENTS

CAUTION! Follow local electrical and safety
codes as well as the National Electrical Code
(NEC) and the Occupational Health and Safety
Act (OSHA).

The machine is rated at 110 to 125 volts AC, 50/60

Hz with a ground. At this voltage the unit draws
about 5 amperes. The use of extension cords is not
recommended.

Locate the unit at or near an appropriate electrical
supply. Be certain that the power source conforms to
the machine’s requirements and that the proper gauge
and type of wire is used. Make connections using the
shortest possible runs of wire. Long runs of wire can result

in reduced voltage.

CAUTION! ALWAYS check the specifications
listed on the back of the machine. It shows the
correct operating voltage and amp draw for
this machine.

GROUNDING

For your SAFETY and machine protection, DO NOT
operate without a proper and secure electrical ground.

If a grounded receptacle is not available, use a proper
grounding adapter.

NOTE: All warranties are VOID if the machine
is used with an ungrounded electrical
connection. Never connect a machine to any
power source that exceeds the specified rating.

LOCATION

CAUTION! DO NOT operate this machine in
explosive atmospheres. Do not subject the
machine to wet or corrosive environments.
Keep all flammable and caustic substances
away from the machine at all times.

This self-contained bag-packaging machine dispenses,
opens and seals pre-made, pre-opened bags from
a roll. The chassis is 300 series stainless steel and

is designed as a tabletop unit to be used in the
vertical position. The machine works with pre-made,
pre-opened bags on a roll up to a maximum 12” (30.5
cm) wide and up to 12” (30.5 cm) long. Running longer
than maximum bags may require factory modifications.

Heavy products may also require factory modifications.

NOTE: Continuous pre-made bags-on-a-roll
that are not pre-opened will not work on this
machine.

The Bag On A Roll Machine is extremely safe and easy
to use even by inexperienced operators. There is no
guesswork, and the machine is designed for the SAFETY
of both your operator and your products. If the sealing

jaws encounter anything significantly thicker than the

bag to be sealed, no heat or pressure is applied –
protects operator’s hands and fingers.

The electromagnetic jaw pressure system exerts pressure
only after the sealing jaws close. The adjustable sealing
system provides heating and cooling time to make
consistently strong heat seals. Once the heat-sealing
cycle is complete, the sealing jaws reopen.

HOW THE MACHINE WORKS

1. Install the pre-made, pre-opened bags on a roll in
the machine.

2. Close the pinch rollers.

3. Set the bag length control for the proper time
duration.

4. Set the sealer control for the material to be sealed.

5. Dispense the first bag to the filling position and air
stream blows it open.

Unit is for indoor use only. Select a location close
to where the products being packaged are stored
or manufactured for best workflow. Also consider
whether the operator will sit or stand while using this
machine. Place the unit on a level, sturdy table that can
support the weight of the machine, the products to be

packaged and those already packaged.

PAGE 3 OF 7 0621 IH-1459

6. Place the product(s) into the open bag.

7. Tear off the filled bag at the perforations.

8. Hold the bag flat and place the open mouth of the
bag between the open sealing jaws near the base
of the machine.

9. Depress the electric foot switch.

CAUTION! DO NOT use the electric foot switch

when liquids are on the floor. A dangerous

electric shock might result.

10. The sealing jaws automatically close on the
mouth of the filled bag.

11. The automatic sealing cycle begins when the sealer
jaws close fully and the next bag automatically
dispenses into the air stream and opens, ready for
filling.

LOADING BAGS

NOTE: If the brake springs are over-tightened,
the perforations between the bags may
separate while the bags are being dispensed.
If the perforations break, it will require
re-threading the bags through the pinch rollers.
If the brake springs are too loose, the bags
may unwind prematurely.

The front access door is located under the pinch rollers.

Pull handle to open door.

1. If loading for the first time: Locate the core-roll shaft
packed for shipment at the factory in the top foam
end cap.) Proceed to Step 3.

2. To change rolls (See Figure 2): Remove core-

roll shaft from the holding brackets by pulling
it toward you and slightly upward in one fluid
motion. Note that one end of the core-roll shaft has
a non-rotation pin.

7. With the roll of bags properly placed and centered
in the machine, raise the lever on the right side of
the machine. This releases pressure on the pinch
rollers and allows easy bag threading.

8. Insert the end of the first bag from the roll between
the pinch rollers. Make sure bag is centered with no
wrinkles. (See Figure 3)

9. Pull the bag between the rollers to approximately
the filling position, then lower the lever on the left
side of the machine to close and lock the pinch
rollers on the bag.

NOTE: A blower system opens the bags for filling.

This system will not work with some products

such as powders, shredded paper and other
very light products. Very light products get

caught in the airflow and will not go into the

bag properly. Some powders may also stick to
the inner surfaces of the bag in the heat seal

area. This may prevent the bag from sealing

properly during the heat sealing process.SET

SET THE HEAT CONTROLS

The machine includes one heating element mounted to
the lower jaw of the heat sealer and one spare, taped

inside the front access door. The heating elements

make a Ribbon Seal approximately 12" (30.5 cm) long

by 1/8” (3 mm)
The heat sealer has an adjustable heat-time control that
may be set from 0% to 100%.

1. Set the HEAT SEALING control to indicate
approximately 30%. (See Figure 4)

2. Flip the BAG ADJUST switch to dispense a bag. (See
Figure 5)

3. Tear the bag off along perforation, then position the
mouth of the bag between the seal jaws.

CAUTION! NEVER attempt to heat seal through
the printed area on a bag, as it will cause
sticking and gumming.

NOTE: Use as little heat time as possible to

obtain the necessary results. Overheating

weakens the seal area on the bag and causes

higher maintenance. The heating element
expands and contracts during each sealing
cycle, eventually causing the element to wear
out. When replacing the element, it may be

timer.

RESIDUAL HEAT – HEAT BUILD UP

The machine is designed to allow sufficient time for
the heating element and sealing compression pad to
cool during the bag dispensing and filling period. It

is not intended for use as a high-speed heat sealer.

Attempting to operate the sealer at speeds beyond its

intended use causes residual heat build-up resulting

in bag seal stretch and melt-through and require early
replacement of the heating element, Teflon® covers
and compression pad.

BAG STOP POSITION ADJUSTMENTS

If the bag in the staging area opens properly, fill it,
tear it off and heat seal it. The next bag dispenses
during the heat-sealing cycle. If the bag does not stop

in the correct position, follow the instructions below. This

is trial-and-error; when using bags of different lengths,
write down the proper settings as you determine them.
The settings will vary slightly from one machine to
another. Initial set-ups may take a few minutes.

4. Depress the foot switch until the sealing cycle starts,
then release. When the sealing cycle is complete,
remove the bag from the Teflon® covered lower
sealer jaw using a left to right or right to left peeling
motion.

INSPECTING THE HEAT SEAL

An acceptable ribbon seal shows the grain of the Teflon®

jaw covers and have a slightly milky appearance. An
acceptable trim seal leaves a fine raised bead at the
end of the bag – no fringe or angel hair.

IF HEAT SEAL IS TOO WEAK

Increase the heat-time setting slightly (clockwise): If the

heat seal does not look complete or if the bag will not
stay closed, repeat the process using another bag until
you are satisfied with the results. Be sure that the seal
area is not coated with a contaminant.

IF HEAT SEAL MELTS THROUGH

Decrease the heat-time setting slightly
(counterclockwise): If the seal melts through, too much
of the bag material extrudes away during sealing, the
top of the bag flops back on itself or if the sealed ends

look shrunken. Repeat testing using another bag until
you are satisfied.

IF BAG STOPS TOO LOW ON THE MACHINE

1. Decrease the BAG LENGTH setting slightly
(counterclockwise). Use the coarse or fine adjusting
control as needed.

2. Flip the BAG ADJUSTMENT switch up or down until the
next bag is in position for filling.

3. Fill, tear off and heat-seal the bag.

4. Repeat until the next bag stops in the proper
position each time.

IF BAG STOPS TOO HIGH ON THE MACHINE

1. Increase the BAG LENGTH setting slightly (clockwise).
Use the coarse or fine adjusting control as needed.

2. Flip the BAG ADJUSTMENT switch up or down until the
next bag is in position for filling.

3. Fill, tear off and heat-seal the bag.

4. Repeat until the next bag stops in the proper
position each time.

MAINTENANCE

If you encounter any problems with the Uline
Bag on a Roll System, contact Uline Customer
Service at 1-800-295-5510.

CAUTION! Never attempt to make heat seals

without the lower Teflon® cover over the
heating element and lower sealing jaw.

REPLACING THE LOWER TEFLON® COVER

To replace the lower Teflon® cover roll:
(See Figure 7)

TEFLON®JAW COVERS

Both the upper and lower jaws of the heat sealer are
covered with a Teflon® glass cloth to aid heat sealing
and prevent sticking. Since the heat source is in the

lower jaw it is exposed to greater abuse and is therefore

larger and easily repositioned.

REPLACE UPPER JAW COVER

Replace the upper Teflon® cover if it becomes torn,

burned or the sealed bag sticks to it. It is held in place

by a spring and is easily replaceable.

REPOSITION LOWER JAW COVER

The lower Teflon® cover provides an easily
repositionable sealing surface. The cover is anchored
at one end to a roller held in place by two screws; the
other end passes through a clamp-type retainer on the

face of the machine.

To reposition the lower Teflon® cover:

1. Loosen the two plastic screws holding the clamp.

2. Using either one or both of the knobs located on

the sides of the machine, rotate the roller slightly so
that a new seal area is positioned over the heating
element. (See Figure 6)

1. Loosen the two plastic clamp screws and rotate the
roller knob with one hand while pulling the trailing
end of the Teflon® up with the other until the two
roller mounting screws are visible.

Figure 7: Replacing lower Teflon® cover

2. Remove the two screws (use either a magnetic or
starter screwdriver). Keep the screws for reuse in
mounting the new Teflon® cover roll.

3. Install the new Teflon® cover roll by passing the
mounting screws through the two eyelets and into
the roller. The screws should be snug. Do not over­tighten as damage could result.

4. Rotate the roller knob, winding the Teflon® cover
onto the roller. Insert the free end behind the clamp.
To reduce waste, put as little Teflon® beyond the

end of the clamp as possible.

REPLACING COMPRESSION PAD

Over time the silicone rubber compression pad

becomes brittle and pitted and needs to be replaced.

1. Remove the upper Teflon® cover by first removing

Figure 6: Repositioning lower Teflon® cover

3. After repositioning, retighten the clamp using the
same two plastic screws.

4. Tear off the used Teflon® material below the clamp.
Replace the roll when there is no more usable

The heating element expands and contracts during
each sealing cycle and will eventually break over time.

Replace using only Uline heating elements.

Make sure that the machine is turned off and
the power cord is secured before working on
the machine.

Any attempt to use elements designed for use
on another machine or in another application
may not work properly and may cause
damage and/or create a dangerous situation.
Use of non Uline parts will void all warranties.

1. Loosen the two clamp mounting screws and rotate
the roller knobs to rewind the Teflon® onto the roller
to expose the heating element. (See Figure 9)

2. Remove the heating element retaining nuts at each
end of the element (keep for reuse).

3. Remove the old heating element and discard.

4. Inspect the insulator on the lower jaw for signs of
cracks, pits, burn marks, etc.

5. If the insulation material is worn replace it before
installing the new heating element. Remove the
old insulator when necessary, clean the area,
apply a smooth coating of RTV adhesive, install the
replacement insulation and allow it to dry for several
hours before installing the new heating element.
