4.1 Function
The All-In Sealer is a band sealer for packaging a wide variety of products in large
quantities. The products are packaged in ready-to-use bags and then sealed. The
sealer can be used for sealing ready-made bags made of polyethylene (PE),
polypropylene (PP), thin PVC and various laminates with thicknesses of between
20µm and 150µm.
[*****]
Never use the All-In Sealer for any other purpose.
[*****]
The sealer is not suitable for the following applications:
• use in cleanroom environments
• use in medical or sterile environments
• use in explosive environments
• use with toxic, suffocating or irritant gases
• use in dusty environments

3. Conveyor belt
4. Setting the distance and height of the sealing unit with respect to the
conveyor belt.
5. Frame with wheels
The sealer consists of a wheeled frame on which there is a conveyor belt and a
housing. The housing comprises the electrical and drive components; the
operating panel is mounted on top of the housing. During maintenance work, the
housing can be tilted to make the interior easily accessible.
The conveyor belt transports the bags that are to be sealed past the heating
blocks, the press rollers, the cooling plates and the after-press rollers that are
located inside the housing.
The height of the conveyor belt can be adjusted to let it line up seamlessly with
the infeed and outfeed belts. The vertical distance between the conveyor belt and
the housing can also be adjusted so that bags of various different heights can be
sealed. The horizontal position of the conveyor belt with respect to the sealing
unit can be adjusted to position the bags as centrally as possible on the conveyor
belt.

7.3 Replacing the PTFE Belts
[*****]
Warning! The heating blocks may still be hot, even if the sealer has
been switched off for a while.
[******]
Replace the PTFE belts as follows:
[*****]
1.
Move the cooling plate, the after
-
press
roller and the heating block to their
uppermost position.
[*****]
Pull the lifting pin up and turn the lifting plate in such a way that it
protrudes above the edge of the protective cover.
[******]
2.
Push the two tension rollers inwards until
they lock in place.
[*****]
When a tension roller is pushed inwards, the locking pin falls into a
recess, which prevents the tension roller from springing back.
[******]
3.
Remov
e the V
-
belts by pushing them off
the pulleys with a rotating motion.
Page 29
Maintenance 29
4.
Remove the old PTFE belts and put the
new ones in place.
[*****]
Make sure there are no creases or folds in the PTFE belts. This can
make them break during use.
[*****]
5.
Pull the
tension roller locking pins
upwards and let the tension rollers spring
back gently.
[*****]
Make sure that the PTFE belts run smoothly over the rollers.
[******]
6.
Place the V
-
belts back over the pulleys.
[*****]
Make sure that the V-belts run smoothly over the rollers, with the
serrated side facing outwards.
[******]
7.
Move the cooling plates, the after
-
press
roller and the heating block back to their
lowest position.
[*****]
Pull the lifting pin up and turn the lifting plate so that the lifting pin
can go back down all the way again.

Replace the V-belts as follows:
[*****]
1.
Remove the V
-
belts by pushing them off
the pulleys.
2. Put the new V-belts back over the pulleys.

1.
Loosen the nut at the back of the shaft by
one full turn.
[*****]
Do not undo the nut completely, or else the tension roller will not stay
suspended.
[*****]
2.
Slide the tension roller to the left or right
to increase or decrease the V-belt tension
respectively.
3. Tighten the bolt at the back of the shaft
again.
[*****]
The long belts must be able to move up and down about 1 cm in the
middle; for the short belts, the play must be 0.5 cm.
[*****]
A V-belt that has to be tensioned frequently is worn and should be
replaced.

[*****]
1.
Turn the adjuster
nut to
alter the contact
force.
[*****]
T
ry to keep the contact force as low as possible in order to minimise
wear and tear on the PTFE belts.

difficult to seal. Always check that the bag does not get blocked or
stuck during sealing.
[*****]
Turn anticlockwise to increase the contact force and clockwise to
reduce it
[*****]
Note that the adjustment depends on the position (horizontal or
vertical) of the housing.
[*****]
Adjust both nuts equally.

7.12 Motor Set-up
The machine has an automatic motor set-up function. This motor set-up function
must be carried out when a motor is replaced. During this set-up the motor will
run at full speed for a few seconds. Be aware that the machine can run safely for
a few seconds.
To perform a motor set-up follow the next steps:
• Select the ‘SPEED’ mode with the ‘PROG’ button.
• Press the ‘PROG’ button for 5 seconds till ‘SP1’ appears in the display.
• Start the set-up routine by pressing the ‘PROG’ button. The motor will run at
maximum speed for a few seconds.
• End the function by pressing the ‘PROG’ button for 5 seconds till the SPEED
settings appear on the display.
7.13 Correction factor
The machine has correction factors to adjust the motor if necessary. This factor
(%) will affect the motor output. If set at e.g. 90 the motor will run slower and set
at e.g. 110 the motor will run faster.
To perform a motor set-up follow the next steps:
• Select the ‘SPEED’ mode with the ‘PROG’ button.
• Press the ‘MOTOR’ and ‘PROG’ button simultaneous for 5 seconds till ‘CF1’
appears in the display.
• Press the ‘PROG’ button.
• Set the CF1 setting with the ‘UP’ or ‘DOWN’ button. (Minimum 85 and
maximum 115).
• Press the ‘PROG’ button to return to ‘CF1’.
• End the function by pressing the ‘PROG’ button for 5 seconds till the SPEED
settings appear on the display.
7.14 Reset to factory settings
The machine has a function to reset all settings to the original factory settings.
Note that if you reset the machine all settings prior made will be lost.
To perform a reset follow the next steps:
• Switch the main power OFF.
• Keep the ‘START/STOP’- and the ‘PROG’ button pressed, while the main power
is switched ON, until ‘rES’ appears in the display.
• Perform a motor set-up.
• Adjust the correction factor if necessary.
