1.0 INTRODUCTION
Please take time to read carefully through this manual and then keep it in a safe place for reference when
required. With over 30 years of experience in the film wrapping business we may be able to help with any
difficulties you may encounter and would be very pleased to assist in any way we can.
The ROBIN sealing machine combined with Polyolefin/Polypropylene film offers the most efficient use of
space and gives the ultimate in protection and eye appeal to your products.
Film is supplied in various sizes and with different perforation patterns (different permeability rates) to suit your
entire product range.
The aim is always to have a neat and tidy pack with the minimum amount of trim waste off the sealing
machine.
Perforated film is suitable for all filled crusty bread/roll products.
Perforated films of a lesser permeability are used for packaging doughnuts, filled soft rolls, sausage rolls etc.
Anti-fog film which is ideally suited to the packing of plated salads and similar moist items, when these are to
be displayed in a chill cabinet, is also available.
Plain (non-perforated) film should be used for packing cake, scones, sandwiches, plated salads etc. except
where these are to be displayed in a chill cabinet.
For speedy and efficient operations it is essential to have simple flowing lines to permit the operator to work
within the area of the machine, always working from right to left. It pays to remember that a clean and tidy
machine should give a clean and tidy pack.
Whilst the ROBIN has been designed primarily for use in Catering operations with attention given to the ease
of hygienic cleaning, the unit can also be effectively used for the packaging of non-food items.

4.0 SAFETY
STATEMENT TO USERS OF
MONO PACKAGING MACHINE PRODUCTS.
(HEALTH & SAFETY AT WORK ACT 1974)
Under the terms of the above Act it is obligatory, rather than simply a matter of good
business practice, to advise our customers on the safe use of our products.
There are no significant known hazards in the use of our products provided they are
handled according to normal good safety practice and in accordance with the information in
this instruction manual. We would nevertheless draw your attention to the following
information which must be taken into account to ensure safe working.
MACHINES
1. The sealing and cutting wire is heated by electrical impulse each time the machine is
operated and therefore care should be taken to avoid touching any part of the wire when hot
or within one minute of operation (due to residual heat).
Cleanliness in the vicinity of the seal wire and the use of minimum heat setting, sufficient
only to seal and cut, is important to minimise any fuming that might occur.
2. Machine electrical compartments must not be opened, due to the danger of electrical
shock, except by a competent person and only then after first being isolated from the mains
electrical supply.
3. This machine is designed for use with Polypropylene (Polyolefin) films and is not suitable
for use with PVC or Polythene.
MATERIALS
1. FLAMMABILITY
Polyolefin films are combustible when exposed to ignition sources and should be stored in
an area equipped with fire control safeguards. This is particularly important if large
quantities of material are to be stored, in which case we recommend heat and smoke
detection perhaps coupled with a water sprinkler system. In common with other combustible
materials, polyolefin films burning freely in a fire will produce complex combustion products
dependent upon factors such as temperature, the degree of ventilation and the fire
dynamics of the situation. It is therefore not possible to specify the combustion products
precisely, but typically they would include carbon monoxide, carbon dioxide, trace levels of
organic compounds and water. For this reason it is recommended that all areas in the
proximity of a fire should be immediately evacuated of all personnel and fire-fighters should
be equipped with self-contained breathing apparatus.

Robin L sealer RevA19 17-01-19
2. HEAT SEALING & TRIMMING
The heat sealing and cutting of plastic films inevitably gives rise to some fumes. Analysis
of the fumes generated by this process and given off from Polyolefin/Polypropylene film
indicates that under typical operation conditions no organic compounds are present in
concentrations greater than 5% of the Occupational Exposure Limits determined by the
Health & Safety Executive, with concentrations generally less than 1% of OEL. However,
even low concentrations of fumes can be irritating to sensitive persons and it is
recommended that adequate ventilation should be provided to the working area to avoid a
build-up of fumes over a period of time. It is advisable to ensure that operatives and
personnel in the working area do not have a history of respiratory or pulmonary illness and
that the sealing equipment is maintained in good and clean condition.
Attention to the cleanliness of the trim sealing heads is important as an accumulation of dirt
or melted plastic can cause excessive fuming. Running the heat control at too high a setting
can also contribute to excessive fuming and it is usually found in these circumstances that a
reduction in the heat setting, combined with increased pressure on the sealing head, will
give a better seal performance.
3. STATIC ELECTRICITY
Build-up of static electricity in rolls of plastic film may cause problems when the charge
earths by sparking. Where work involves potential fire or explosion hazards, steps should be
taken to eliminate safely the static charge and to prevent subsequent recharging during
further processing. Because of the possibility of generating and or discharging an
electrostatic charge, protective wrappings should not be removed from film rolls in areas
where the atmosphere conditions are such as to present a fire or explosion hazard.
4. SLIP
Most plastic films are high slip materials and if allowed to lie on the floor, can present a
safety hazard to pedestrians. Care should therefore be exercised to ensure that scrap off-
trims of film, are tidied away in appropriate disposal containers and not be allowed to litter
the floor.
5. DISPOSAL
Disposal of scrap film should either be through the normal trade re-use outlets, burial or
incineration. Incineration can be used for disposal where the incinerator is designed to cope
with corrosive flue gasses.
NOTE!
The Materials information set out above is based on information supplied by a manufacturer
of Polyolefin Film and is correct to the best of our knowledge and belief. However, whatever
film you decide to use, since the chemical composition may vary from manufacturer to
manufacturer, you must satisfy yourself, by reference to the material supplier, that the
material is safe to use on a heat seal and cut machine such as the ROBIN and that any
fumes given off are not toxic or harmful.
Mono Equipment does not accept any liability whatsoever for any consequences arising
from your choice of wrapping film.

8.0 ADJUSTMENTS
It should be noted at this point that no two heat sealable materials will work the same at the
same machine settings.
WIRE TEMPERATURE CONTROLLER.
This component is used to control the level of impulse temperature. The desired setting is
controlled by altering the digital display by pressing the plus or minus buttons.
WIRE TEMPERATURE.
Controlled as set out above. For all gauges and types of film it is recommended that a low
setting is first tried, gradually increasing to find the lowest setting at which a satisfactory
clean cut-off is achieved. The number (on the controller) thus established should be noted
for future reference in relation to the particular type and gauge of film in use. On no account
should too high a setting be used as this will reduce the life of both sealing wire and sealing
pads and might give rise to unpleasant fumes.

OPERATING INSTRUCTIONS
1. Place the desired type and size of centrefolded film on the film cradle with
the open side of film facing to the front. To align the film relative to the front
seal pad and to suit the product to be packed, slide the cradle backwards or
forwards to the desired position.
2.
Place the loading platform/film separator between the film layers pulling the
free end of film under the seal arm. Ideally the platform should be
positioned so that it's tip comes to within half the pack height of the film fold
line.
3.
Switch power 'ON' and observe 'POWER ON' light is illuminated.
4.
Set 'WIRE TEMP.' to specified recommendation and with the film under the
right-hand sealing arm, lower arm onto the film and hold down under
moderate pressure. When the light, on the temperature simulator, goes out,
release the arm and observe welded film. There should be a clean cut-off
and weld with no gaps evident.
5.
Place product between the film layers, on the loading plate and move to the
left and into the sealing area. The product and film should always be pulled
into position rather than pushed to protect the leading seal.
6.
Close the seal arm and hold down firmly until the simulator light goes out, at
which point the arm can be released as the film will have been welded and
cut from the roll.
WASTE FILM IS GENERATED FROM THIS PROCESS
AND, SINCE IT IS SLIPPERY AND COULD CAUSE AN

11.0 MAINTENANCE
ALL CLEANING AND MAINTENANCE OPERATIONS MUST BE MADE WITH THE
MACHINE DISCONNECTED FROM THE POWER SUPPLY
Weekly
Check condition of sealing pads and top cover tape for excessive burn and replace tape if
necessary.
Check condition of and clean, seal wires and seal wire insulation strips. To clean wires,
operate machine two or three times to heat the wires, switch off machine, then with a wire
brush, clean the wires. Repeat if necessary. In the absence of a wire brush, a ball of
Crispywrap film or a cloth can be used.
Six Monthly (Mechanical)
Carry out weekly service.
Check condition of seal wire insulation strips and replace if badly burned showing deep
grooves. To replace, cut off old strip, clean metal surface and apply a suitable contact
adhesive. Apply new strip to prepared surface and press down into position. When replacing
insulation strips, always replace the sealing wires and ensure when so doing that the wire
tension springs are properly fitted.
Check condition of seal pads. If cover tape (PTFE) has been changed at regular weekly
service periods, these components should be serviceable. If however, the pads have been
badly burned, new pads should be fitted. Pads may NOT be turned over to extend their life,
due to a metal strip used in construction which could cause an electrical short.
Six Monthly (Electrical)
Disconnect machine from Mains Electrical Supply and remove the Console rear cover.
Inspect condition of wiring insulation and examine all terminals for security.

Robin L sealer RevA19 17-01-19
SERVICE REPAIRS (MECHANICAL).
SEAL PAD COVERING.
A length of adhesive backed, 13mm wide, P.T.F.E. glass tape, is fixed to the pads for
protection. This replaceable tape should be renewed when seals become sub-standard,if
the film sticks to the pad or pronounced burn marks are apparent.
SEALING WIRE INSULATION STRIPS.
These components may become damaged due to incorrect machine setting or heavy usage
and require replacement.
SEALING PADS.
These components may become damaged due to incorrect machine setting or failure to
replace the cover tape and require replacement.
CAUTION! Isolate machines from mains electrical supply before opening
electrical compartment
LEVELLING OF SEALING ARM & ADJUSTING 'HEAT ON' SWITCH.
The arm is levelled by adjusting the two bearings housed in the Control Console. After
isolating the machine from the Mains Electrical Supply and opening the Console rear door,
the procedure for adjustment is as follows:-
Pull the arm down onto the pad and look along the length of both pads to see if there are
any gaps.
If gaps are noted, adjust following the steps below:-
a. If the left-hand end of the front seal arm is not touching the seal pad,
raise the right-hand bearing.
b. If the right-hand end of the front seal arm is not touching the seal pad,
raise the left-hand bearing.
c. If the rear of the transverse seal arm is not touching the seal pad, lower both bearings.
d. If the transverse seal arm is touching the rear of the seal pad long before the front seal
arm reaches the front seal pad, raise both bearings.
ARM BEARINGS POSITION

Robin L sealer RevA19 17-01-19
If there are no visible gaps, check fine levelling using a 1" wide strip of paper. Place the
paper strip between the pad and seal arm, close the arm using one hand and with the other,
pull the paper across the pad, checking whether the paper is being gripped. This should be
tried along the length of both pads and if an area of poor grip is found, adjustment should be
carried out as detailed above.
A further test is to use strips or a sheet of Kraft paper over the full length of both pads and
operate the machine. When the seal frame releases, burn lines will be seen on the Kraft
paper which should be of even thickness, indicating even pressure over the full length of
both wires. If the burn is not even or there are gaps, the seal arm should be levelled.
ADJUSTING 'HEAT ON' SWITCH
After adjusting the bearings, check that the "Heat On" Switch actuating screw is set so that
the switch is actuated when the seal arm is within 3mm to 4mm of touching the front seal
pad.
