Installing the BEL 290
1. Remove the through-bolts that secure the machine to the shipping base.
2. If possible, use a forklift to move machine off its base, with wooden blocks between the forks
and the frame.
3. While machine is elevated, install the footpad extensions or castor extensions to the bottom
of each leg and adjust them for the desired operating height.
4. Position the machine where it is to be used.
LEVELING THE MACHINE
The machine should be installed in a level position to avoid frame stress and ensure optimum
performance. An adjustable height footpad kit is included as standard equipment and can be
used to level the machine on an uneven floor.
The machine should be anchored to adjoining equipment or the floor to prevent any movement
of the machine by reactive forces that may occur as sealed cases are being driven through the
machine outfeed.

INSTALLING THE TAPE HEADS
Tape dispensing heads are mounted using the pins on their sides. These pins fit into
corresponding slots in the upper and lower tape head mounting brackets. Machines are usually
shipped with the tape heads secured in their brackets. To reinstall the tape heads, lower them into the
brackets to align the pins on their sides with the slots in the brackets. Follow these steps:
1. On the bottom tape head, slide the rear pins on the head down and back into the ‘key’-
shaped slots. The front pins will then drop into vertical slots of the bracket. The head is
held in place by its own weight.
2. On the top tape head, both the front and rear pin heads engage the key-shaped slots in the
tape head mount. Push the top head back in its holder to secure it between spring-loaded
retainers so that it will not move out of position.
Please consult the tape head manual for instructions on the mounting of tape rolls and the
proper threading of tape through the applicator head.
POWER CONNECTIONS
Electric
The BEL 290 is equipped with single phase 110-120 VAC electrics to and manufactured NEMA
12 specifications. A 1/2 horsepower TEFC motor that draws eight amps powers the drive
system. A minimum AWG 14 gauge power extension cord with standard three-pin connection
must be used to connect the machine to the power source.
If any electrical connections are needed to install the machine, they must be handled by a
qualified electrician in your jurisdiction.
Compressed Air
The BEL 290 requires an air supply, which must be clean and dry, with a PSI between 80 and
120 and an optimal pressure of 90 PSI. The kicker regulator must always be set at 70 PSI. The
volume of air required for the BEL 290 is rated at 0.1 C.F./cycle at 90 PSI. (6 Bar). The
incoming air supply line must be of sufficient diameter to provide an adequate amount of air
without pressure drops when the machine is cycling. A 1/2” air line size is recommended.
One of the most common causes of inconsistent machine performance is inadequate air supply.
Therefore, meeting machine air requirements is important to assure satisfactory operation.
The BEL 290 is equipped with an electric air ‘ON/OFF’ valve, an air filter/regulator and second
coalescing filter which should be checked periodically to ensure that the air pressure is
regulated to the proper setting, and that the filters are not contaminated.
PLEASE NOTE:
Best performance with BEL machines will occur when the machine is adjusted, operated and
maintained in accordance with the instructions in this manual. We cannot be responsible for
unauthorized changes to the machine or methods of its operation.
The following information is a reference guide for our standard machines. We strive to provide
up-to-date manuals with machines but we are continually improving our products, and the details
in the manual provided might not exactly match the machine at the time it is shipped. Many
machines are modified in response to customer requests or as required by the case samples
supplied at the time the machine is built, so the manual may not provide a complete reference to
the changes or modifications. If there are any questions about your machine not covered by the
manual, please contact us and we will do our best to provide the additional information you
need.

Machine Adjustments
Safety:Disconnect machine electrics and compressed
air before making any machine adjustments.
There are only two main, quick adjustments required in setting up the BEL 290 to run a
particular case size:
1. Case width adjustment ‘D’- Use the hand crank on the side of the bottom frame
to move side-belt conveyors in and out to fit the width of the case.
2. Case height adjustment ‘H’- Use the side hand crank on the top guarding frame
to vertically adjust the machine head with the top flap folders and tape head to match
the height of the closed case.

H
In practice, it is best to first open up the adjustments first to fully clear the height and width of
case.

CASE HEIGHT ADJUSTMENT
Case Dimension ‘H’ Adjustment
Use the case height crank and scale on the side of the arch to adjust the case height to
Dimension ‘H’.

CASE WIDTH ADJUSTMENT
Case Dimension ‘D1’ (Conveyor Adjustment)
Use the case width crank and the scale at the front of the conveyor to set Dimension ‘D1’. The
case width crank can be connected to the case width leadscrew on either side of the machine
frame.
An alternative method to using the width scale is first to move the conveyor belts apart until they
are wider than the case to be run. Then, adjust the conveyor belts back in until they lightly
contact the case sides. Remove the case through the machine infeed and wind the belts in by a
further one-half turn. This usually moves the conveyor to the correct position for a good grip on
the case.

SCALE
Note: Depending on case fill, weight, dimensional variations, and conveyor belt wear, it may be
necessary to make minor adjustments to the settings to ensure best performance.

Case Dimension ‘D2’ (Major Flap-folding Rods)
If necessary, loosen the bolts that lock the top major flap folding rods in position and adjust their
position so that they capture the top case flaps and fold them down ahead of the top tape head
as the case passes under them. The rods will need to be moved inward toward each other for
narrow cases and outward for wide ones.

BEL 290 FULLY AUTOMATIC CASE TAPE SEALER 10
Case Dimension ‘D3’ (Case Side Compression)
Adjust the side-compression rollers to control the tendency of the upper sides of the case to
expand due to incorrect top flap folding and perhaps case overfilling. The side-compression
rollers should minimize the gap between the top major flaps while they are being taped.
