It is possible to shrink the film by using the Tunnel. This series can be connected to the
conveyor belt at the outfeed of the sealing machines.
In order to achieve excellent packaging, the film is sealed at half the height of the product.
Raising (or lowering) the conveyor belts requires making adjustments to the tunnel blinds, as
it is essential to avoid losing heat during the shrinkage operation.
4.1 IDENTIFICATION DATA AND TECHNICAL DATA OF THE
MACHINE
Each machine is provided with a plate where it is easy to recover data which must be
communicated to the manufacturer in case of problems or when requesting spare parts etc.
(ref. 1-2-3-4). This plate also carries electrical technical data for installation of the machine (ref.a-b-c-d).
1 - Model
2 - Serial number
3 - Machine code
4 - Year of manufacture
a - Nominal voltage
b - Nominal frequency
c - Nominal power
d - Nominal current
ATTENTION! Before performing connections to the electrical mains, make sure that the power
supply voltage is compatible with that shown on the plate.
4.2 SHRINKING
Film shrinkage is achieved by the forced circulation of hot air around the package. The air is
heated by a heat-controlled resistor unit. If the sealing breaks during the shrinking it is possible
to increase the speed of the belt or to lower the temperature of the resistors by acting on the
tunnel's control panel.
4.3 REGULATION OF BAFFLES
The baffles A: reduce hot air flow below the product.
The baffles B: direct the hot air flow coming from the baffle A.
(Fig. 1) - The baffle A is closed and the air flow is conveyed below the product to be packed.If bubbles should form or the film tear at the bottom of the product in this situation, the air flow
coming from this direction must be reduced by opening the baffles A as shown in Fig. 2 and
Fig. 3.

4.4 ENABLING SWIVEL ROLL MODE
The rolls that carry the product normally turn in order to achieve uniform shrinkage and
therefore improved packaging. At times, however, some types of film may over-adhere to the
rolls and tear when the rolls turn. In order to always choose the best solution for each type of
film, the machine is set up to process the product in "swivel roll" mode and "fixed roll" mode.
In order to make this adjustment, it is necessary to act on lever A, as shown in the figure:
- Holding lever A in a horizontal position, the rolls stay in a fixed position.
- By turning the lever downwards, the rolls turn.
4.5 MACHINE OPERATION WITH OVEN IN HEAT SHRINKING
MODE
Once sealing is finished on the packaging machine, the machine belt carries the product along
the tunnel belt into the thermal chamber for the shrinking process and then out of it on the
designated roller conveyor.
The variables for the shrinking process (internal temperature and conveyor belt speed) are
managed from the tunnel operator panel.

6.3 NATURE AND FREQUENCY OF MAINTENANCE CHECKS AND
INTERVENTIONS
In the manual, the description of the various maintenance operations is often associated to the
symbols described below.
Notes on the general cleaning procedure for the shrinking tunnel
To optimise performance it is good practice to always keep the shrinking tunnel clean.
Accordingly, it is possible to prevent malfunctions and identify and repair any faults while
operating in safe conditions. Be careful during cleaning operations not to act on the set-up of
the safety systems.
ATTENTION! Wait for the shrinking tunnel to cool before removing any debris that may havedeposited on the hot parts.
The table below describes the controls, the checks and maintenance procedures required for
each device in the tunnel in order to keep up optimal performance over time.

6.5 LUBRICATION OF MECHANICAL PARTS
This paragraph provides information concerning lubricants which can be used to keep the
machine perfectly efficient. Should it be difficult to find these lubricants, you may use other
good quality lubricants with the same characteristics as those recommended. Do not mix
different types of lubricants.
List of mechanical parts which require lubrication:
1 - Oven conveyor belt chain
The specific lubricant recommended for the chains of the oven conveyor belt is Mobil
Pyrolube 830, a synthetic ester-based lubricant for parts operating at high temperatures (up
to 230°C). This oil can be applied with a brush, by drops or spraying (even with timers).
The fully synthetic base of Mobil Pyrolube 830 and the consequent low volatility
characteristics limit evaporation of the product at high temperatures and prevent the formation
of sludge and carbon residue. Using this oil instead of other mineral and synthetic oils has the
following advantages:
• Almost no carbon deposits
• No unpleasant odours
• Low consumption due to lubricating capacity of the product allowing you to limit the number
of applications.
• Longer duration of lubricated parts.
• Noise reduction
4 - Reduction gears
They require no oil change since they are the "long life" type.
6.6 REPLACING FLEXTRON MODULES
When replacing a FLEXTRON module, we recommend strictly following the indications
described below:
• Switch the machine off, disconnect power, interlock the general isolator and wait at least 5
minutes before operating.• Disassemble the casing of the electrical panel to access the modules of the FLEXTRON
boards.
• Press on the sides as shown in the figure to remove the connector 1.
• Take the connectors 2 off being careful to act on the body of the connector and not on the
cable.
• Remove the connectors 3 by loosening the screws 4.
• Act on the screws 5 to remove the FLEXTRON modules to be replaced.
After having replaced the damaged module, put all the connectors back on and, before
restoring the connection to the power supply, make sure that the protective casing of theelectrical panel has been put back in place.
