Installing the BEL150
Transportation and Storage
The BEL 150 should not be stored or transported in extreme temperatures. Transport and store
in a covered environment not directly exposed to the natural elements, such as rain, snow or
wind. When transporting the machine it should be safely secured to prevent movement.
Remove the through-bolts that secure the machine to the shipping base. Use wooden dunnage
blocks under the frame when using a forklift to lift the machine off its shipping base and to position it. If
the machine is equipped with casters use the caster brakes when the machine is in the desired
location to prevent movement.
Leveling the Machine
The machine should be installed in a level position to avoid frame stress and ensure optimum
performance. The machine is equipped with adjustable leg-height and leveling pads as standard
equipment and adjustable casters are available as an option. Once the infeed / outfeed height has
been set, use a spirit level both along and across the frame side-rail members to level the
machine.
Power Connection
The BEL 150 is equipped with single-phase 115 VAC / 60 HZ electrics and manufactured to
NEMA 12 specifications. The drive system is powered by a 1/2 horsepower TEFC motor that
draws eight amps. A 14 gauge (AWG) power extension cord with standard three pin connection
must be used to connect the machine to the power source.
A dedicated electrical circuit is recommended for this machine. If any electrical connections are
needed to install the machine, these must be handled by an electrician qualified in your
jurisdiction.

Installing the Tape Heads
Tape heads are mounted with pins on the sides of the heads that fit into corresponding slots in
the tape head mounting bracket. Lower the tape head into the bracket aligning the pins with the
slots. The upper tape head, when pushed firmly toward the rear of the machine in its mounting
slots, is held in position by a thumb screw. Please consult the tape head manual for instructions
on the mounting of tape rolls and the proper threading of tape through the applicator head.

Starting the Machine
To start the machine, press the green START button on the switch. BEL machines are fitted with
magnetic starter switches for added safety protection from accidental start- up in the event of a power
outage or disconnection. The switch is positioned at the center of the frame arch for easy access from
either side of the machine.
Use the red STOP button to stop the machine.
FEEDING CASES
First fold down the top flaps of the case by hand. Holding the top flaps closed, direct the case between
the infeed guides until it contacts the side-belts. The belts grip the case and transport it through the tape
heads that apply tape to the top and/or bottom flaps. Because of the BEL Uni-drive feature, cases
presented squarely to the machine will retain this squareness throughout the sealing cycle, providing a
stronger seal and better appearance.
Note: If the case sides are bulged by the product inside, the use of an optional side compression roller
(Kit # 70-007 for the BEL 150, 70-185 for the BEL 150X) is recommended to draw the top major flaps
together to effect a tighter seal. This option is also recommended when the case being sealed has a sealed
length that is less than half of the case height.

Belt Tensioning and Tracking Adjustment
Tension the belt by tightening the top and bottom tensioning bolts. The tension of the belt should be just
enough to prevent belt slippage or so that approximately one inch of play is available when the belt is
pulled sideways by hand in the center of the machine. With the conveyor running, tighten the upper and
lower bolts to position the belt so that it is running true and not trying to ride up or down on the idler
pulley.
Uni-Drive Conveyor Chain Drive Tension
The Uni-Drive side-belt conveyor is designed to keep the case square during sealing, which results in a
technically stronger seal and a better-finished appearance. This is achieved by linking the drives of both
conveyor belts to a single motor and gear-reducer that inherently synchronizes belt speeds better than
other belt drive systems on the market. Uniform chain tension is maintained automatically during case
width adjustments through a self-compensating serpentine configuration.

Chain tension is preset at the factory but if the drive becomes noisy or needs adjustment then adjust as
shown below. Proper tension is achieved when the horizontal sag in the chain measures between 1/8 inch
and 1/4 inch with drive belts in a fully opened position.
1. At the conveyor drive motor corner of the machine, loosen the idle sprocket mounting bolt
enough to allow it move in its slot.
2. Unfasten the flexible plastic bellows on top of the stainless steel safety cover and remove the
cover.

SAFETY: The safety covers must be replaced before operating the machine.
The optional BEL 150 Spare Parts Maintenance Kit contains all of the parts necessary for maintaining the
Uni-Drive conveyor. See the Technical Reference manual 66- for details, and contact the factory or your
local Belcor distributor for the kit’s price and availability.
Replace the stainless steel safety covers before operating the machine.

ARCH CROSS-MEMBER VERTICAL SLIDE ADJUSTMENT
The machine arch cross-member supports the upper tape head holder on the BEL 150. It mounts to the
arch assembly with vertical slide bar bearings that ride inside the arch columns, allowing the cross
member to move smoothly up and down for case height adjustment.
The bearings are made of a special hardwearing plastic material but may need periodic adjustment to
compensate for wear or for loosening due to frequent adjustment or operating vibration. If worn or loose,
the bearings allow excessive movement of the upper tape head holder and may affect taping performance.
There are wedge-shaped spacers between the bearing bars at the top and bottom with a threaded rod
adjustment between them. Tightening the nuts on the rod will reduce the bearing clearance.

Troubleshooting Guide
Section 1 - Corrugated Case Quality & Specifications
Corrugated case quality is a major factor in smooth running and quality sealing. The following points
will help determine if you have a case size or quality problem:
1. Case dimensions: Ensure that the products fill the case efficiently and do not bulge, over-fill, or
under-fill the case. Re-sizing of cases can often result in cost savings by using the correct case size
and material weight. Consult your corrugated case supplier, for help to achieve this. A correctly
filled case will help the automatic process by supporting the case body during flap folding and the top
flap sealing.
2. Score (fold) Lines: Ensure that the scores in the cases are as well defined as possible to help with the
automatic folding process. Your corrugated case supplier can help with this by making sure that
correct scoring pressure is used for your case specification. This is one of the most common causes of
poor case- closing performance
3. Corrugated case weakness: The case manufacturing process can damage the fluted construction of
corrugated board. Points to watch for:
a. Crushed corrugate: Ensure that the flutes have not been crushed overall, causing the case to
have a soft and limp feeling. This causes poor case rigidity during machining and also does
not give your product the protection it deserves.
b. Bands of crushed corrugate flutes: Selective bands of crushing, usually parallel to the case
flutes, can cause failure lines down the case and result in poor machine-handling
performance.
c. Case storage: Flat cases should be stored in dry conditions and on a flat surface. Be careful
not to stack excessive weight on to the cases, as crushing can result.
4. Case squareness: The glue joint where the manufacturer glues the flat case together often can
present a quality problem if they are misaligned. This causes the case to be wider at one end than the
other or to be twisted from end to end. Both conditions can cause case jams and poor sealing quality.
5. Flap corner slots: If the corner slots are wide, cases can be automatically folded with a minimum of
interference between major and minor flaps.
6. Overlapped or gapped case flaps: These conditions can be caused by incorrect flap lengths. Fold
the case by hand to see that flaps meet neatly in the case center.
Use your corrugated case supplier’s expertise to help you achieve the correct specifications for your
automatic sealing line.

Section 2 - Conveyor Belt System
The Uni-drive side-belt conveyor system is designed to keep the case square during sealing to produce a
technically stronger seal and a better looking appearance.
Problem: Case Is Not Sealing Squarely.
Despite the parallel drive nature of the Uni-Drive conveyor, the cases exit the machine not square after
sealing. Be sure that:
•the case is square before it engages in the side-belt conveyor belts.
•the side belts are correctly adjusted to case width by the following method:
1. Adjust the belts in until they lightly contact case sides, but so that the case can still slide
through belts if pushed firmly.
2. Remove the case and adjust the belts inwards one-half turn.
•neither of the conveyor belts is slipping on its drive pulley. See the section on belt tensioning
procedure in the Service and Maintenance Procedures section.
•in the case of round can or bottle products, check that belts are set to grip lightly but firmly on case
sides. Excessive side pressure can cause round objects to roll ‘over-center’ and push the case out of
square.
Problem: Depressed or Crushed Band on Lower Case.
If the cases exit the machine with a band of crushed corrugation at the level of the conveyor belts, it is
likely that the case is gripped too tightly in the belts.
Problem: Rubber ‘Dust’ Being Shed by Belt.
A dark gray or almost black dust appears beneath the conveyor belts, particularly at the case exit end of
the machine
•Ensure that the case is clearing the belts as it exits the machine and that outfeed conditions do not
cause cases to back up into the machine.
•Ensure that belt tensioning and tracking adjustments are correct, as described under Service and
Maintenance Procedures. Incorrect settings can cause premature belt wear and possible belt
breakage. (See section on Uni-drive in machine manual.)
Problem: Rattling Noise from the Conveyor Drive.
Although pre-stretched chain is used in the machine drive, the chain over time may loosen and rattle on
the drive cover. Tighten the idler sprocket, as described in the Service and Maintenance Procedures
section.

BEL 150 V.02 Series of Semi-Automatic Uniform Case Tape Sealers 19
65-43-2 12/20/11
Problem: Frequent Belt Breakage.
Belt life will depend on the conditions of machine use, but frequent breakage may be due to one or more
of the following conditions:
•Belt tracking. Ensure that the idler pulley has its camber set so that the belt does not try to ride up or
down on the pulleys. See belt tensioning and tracking adjustment under Service and Maintenance
Procedures
•Belt Tension. The belts may be over-tensioned. The correct setting allows approximately one inch of
slack at center point of conveyor.
•Idler and drive pulley rotation. Ensure that pulleys rotate freely and that bearings are not seized or
excessively worn.
Problem: Machine Jams Frequently.
Turn OFF the machine as soon as the jam occurs and before clearing the jam. Open the belts and raise
the top tape head. Remove the jammed case and debris. Check for the following causes of case jams:
•The top tape head is adjusted too low.
•The product is overfilled or inconsistent, causing intermittent jams.
•The belts are set too tight, causing machine overloading.
•Check the position of the top ski.

65-43-2 12/20/11
Section 3 - General Taping Conditions
Problem: Tape Does Not Stick To Case Surface.
The tape is not bonding to the corrugated board of the flaps or ends of the case to provide a secure seal.
Look for the following conditions:
•Under-filled Case. Ensure that the product provides support under the top flaps so that they are not
simply pushed down or away from the tape head rather than having the tape rolled onto the surface.
•Overlapping flaps. If the outside (major) flaps are allowed to overlap, the ‘step’ created results in an
uneven taping surface, causing poor tape adhesion that can release during shipping and handling. See
comments on flaps (Troubleshooting Section 1, Corrugated Case Quality & Specifications)
•Tape-head roller contact. Ensure that the tape-head contact or wipe-down rollers are making good
contact with the case and that the roller spring tension is correct.
•Dust or dirt. Large amounts of dust or dirt gathering on the casees or in the air will impair adhesive
effectiveness.
•Temperature. Extremely hot or cold temperature may require tapes with appropriate adhesive
formulations for good initial bond and permanent sealing performance.
•Tape adhesive. Ensure the presence and quality of tape adhesive. We recommend the ‘hot melt’
type of adhesive over Acrylic adhesive.
Problem: Tape is not cut uniformly.
The tape is not cut properly every time. In the worst situations, several cases may be taped together.
Check the following conditions:
•Tape head position. If the top tape head is set too high, the cut-off knife will not be fully activated
resulting in poor cut off. The tape-head side plates should be within 1/16 to 1/8” of the case. Ensure
also that cases ride fully down between the conveyor belts to provide proper contact with the bottom
head cut off knife.
•Knife extension. Ensure that the knife extends enough to fully contact the tape during the cutting
stroke.
•Tape tension. Unroll tension should be smooth and not too tight, as a ‘snap back’ caused by
stretched tape can cause a jagged cut-off and cause tape pieces to be stuck to the blade.
•Clean knife. Clean the blade and apply a little silicon or oil to avoid adhesive build-up on the sharp
points.
•Knife blade wear or damage. Blades must be very sharp to work well. The points are easily
damaged if contacted by any hard material. Replace the blade if it seems dull.
•Cut-off spring tension. Ensure that the spring that provides power to cut-off arm has enough tension
to cut through the tape. Replace the spring if it is too weak.
SAFETY CAUTION – Tape head knife is very sharp
