Description
The OLIVER Model 1808-D Tray Sealer has been designed and manufactured to
provide a machine of very high quality, yet with a cost-effective approach to producing
film lidded trays. The Model 1808-D Tray Sealer is designed to heat seal film to
paperboard and thermoplastic trays at speeds of up to 25 trays per minute. The
machine can be operated wherever an adequate power outlet is available (see power
requirements). The machine consists of a continuous motion conveyor system, a film
feed station, a heated sealing roll and a film cutter unit. The machine is supplied with
casters for ease of relocating. Its design will provide years of efficient, trouble-free
operation requiring a minimum of maintenance.
The Model1808-D Tray Sealer is of stainless, plated, and painted steel construction for
easy cleaning and maintenance.
Oliver Products Company, who has a reputation of serving the Food Industry for over 70
years, backs this equipment.

INSTALLATION INSTRUCTIONS
INSPECTION
Upon receipt and prior to uncrating, inspect the exterior of the crate for damage. If
damage is noted, indicate damage on the Freight Bill and immediately contact the
Freight Carrier and notify them of the damage. Have a freight claim filed.
This must be done at the Recipients location and not at the Shipper’s location.
UNCRATING
Remove the tie-downs and any other materials used in attaching the machine to the
skid. Lift the machine off the skid in a safe manner. Remove any tape and plastic tie
bands that were used to secure parts for shipment.

OPERATING INSTRUCTIONS
NOTE: Conveyor motion can be stopped at any time by lowering the operating
handle or pushing the E-Stop Pushbutton (Emergency only). The E-Stop button
will also turn off power to heaters. Under normal operating conditions, conveyor
is stopped by Lowering Operating Handle.
Before operating the machine make sure it is plugged into a grounded 208-240V.A.C.
outlet rated for 10 AMPS. Once the machine is plugged in, the conveyor can be run
using the “Operating Handle” along with the “Start” pushbutton.

The speed control knob is used to adjust the machine speed by turning clockwise to a
higher number for higher speed and counter clockwise to a lower number for lower
speed.
Before you are ready to run production, turn the Heated Roll “ON/OFF” ( I/O) switch to
the “ON” ( I ) position. This will supply power to the heater elements in the heat seal roll
to bring it up to temperature. You should turn the power on approximately 20 minutes
prior to the time you want to begin production. This will give the heat seal roll ample
time to heat up. At the end of the day, turn the “ON/OFF” ( I/O ) switch to the “OFF” ( O )
position. Be sure infeed gate is in place, discharge cover is closed, and E-stop is
released for heat seal roll to be energized. Otherwise heat seal roll temperature
will not rise and therefore will not seal properly.

(“OPERATINTING THE MACHINE “ CONTINUED)
The conveyor can be run while the heated roll “ON/OFF” switch is in the “OFF” position.
This allows for cleaning the conveyor without having the heat seal on. It is also a good
idea to unplug the machine when it will not be used for a lengthy period of time.
The machine will stop if the infeed gate interlock switch has been tripped, the discharge
cover is opened or the E-Stop button is pressed. When this situation occurs, set the
infeed gate back to its proper position, close the discharge cover and make sure E-Stop
button is released (turn anti-clockwise). If the infeed gate has been repositioned
properly, the discharge cover is closed and E-Stop button is released (turn anti-
clockwise), then the temperature controller display should be active and machine will be
able to operate.
The infeed gate can be removed by pushing forward on the handle and lifting up and
out. To replace the guard, drop the guard fingers into the notches and pull the handle so
the interlock engages. See the photo below for the location of the guard and interlock
switch.

(“OPERATING THE MACHINE” CONTINUED)
Filled trays are manually placed in the conveyor of the machine. Film is fed from the film
supply roll which must be threaded onto the machine as illustrated on the “Film
Threading Diagram” which is shown in the photo below. Pull enough film so the film can
be pushed down in the gap between the tray carriers. The film should hang down
through the carriers about 4 to 5 inches.

The machine is started by lifting the operating handle and pressing the START “I”
pushbutton. This should be done in a swift manner which allows the heat seal roll to
come into contact with the tray and film quickly, as the conveyor starts moving. This
procedure prevents voids in the seal area during and stopping. Also, when lowering the
handle to stop the machine, it should be done in swift manner as well.
CAUTION
Avoid leaving the heater roll in the lowered position with the conveyor not
moving. This will cause damage to the machine and any trays that are under the
heated roll.

After a few sealed trays have come off the end of the machine, check to see if the film is
centered from side to side on the trays. If it is not, the film roll needs to be moved to one
side or the other on the film mandrel. There are thumb screws in the stainless steel
collars on each side of the film mandrel. First loosen the thumb screw on the side which
the film roll needs to move toward and move that collar about one half as far as you think
the film is off center and tighten the thumb screw. Then loosen the thumb screw on the
other collar and move the film roll holder up against the film roll core and tighten the
screw. After getting the film centered on the trays, check to see if the film is sealing to
the trays without excessive wrinkles. If there are excessive wrinkles, it might be that
there is not enough tension on the film roll. This can be adjusted with the three thumb
screws on the plastic film roll holder. Turning the screws clockwise will increase the film
tension. If the film tension is too tight and the film comes off of the roll too hard, back the
screws off by turning anti-clockwise.

As the trays come off the end of the machine, they are fed out of the tray carriers onto
the discharge table. This table can be adjusted in and out and, up and down. These
adjustments are shown in the photo below.
CAUTION
When making either of these adjustments, care must be taken to ensure that the
discharge table does not get adjusted too close to the tray carriers. Doing so can cause
damage to the machine.
The purpose of this adjustment is to get the trays to smoothly exit the machine as they
make the transition from the tray carriers onto the table. After the trays are on the table,
each tray will be pushed off the table by the next tray.

CLEANING PROCEDURES
WARNING
DISCONNECT FROM POWER BEFORE CLEANING OR SERVICING.
CAUTION
This is not a wash-down machine! Do not directly spray any area of this machine.
Clean machine areas by using only a damp rag or damp plastic scouring pad.
Clean the Heat Seal Assembly before cleaning the Conveyor because the debris that will
be removed from the Heat Seal Assembly will fall onto the Conveyor.
Inspect the Heat Seal Roll for accumulation of debris (food Product). Clean off the
debris with a damp plastic scouring pad such as “Scotch Brite” brand pads.
CAUTION
Always allow heated roller to cool before cleaning Heat Seal Assembly.
Do not use metallic instruments such as screwdrivers or knives to clean the Heat
Seal Roll, this will cause damage to the sealing surface. Also, do not spray the
Heat Seal Roll. Use only damp rags or towels to remove the loosened debris from
the rolls.
Tray carriers, if heavily soiled, can be removed for cleaning.
CAUTION
Only remove approximately one infeed section of the tray carriers at one time.
Removing all the tray carriers and advancing the conveyor can cause severe
damage to the machine.
Remove the infeed section of tray carriers, wash, replace, advance conveyor, and repeat
until all tray carriers have been cleaned.
Check the corner areas of the frame for accumulation of debris that may have
accumulated due to spills.
NOTE
These cleaning recommendations are not meant to replace or supercede plant
standard manufacturing procedures or regulatory requirements.
If Plant procedures call for the use of sanitizing solutions, use a rag dampened
with the sanitizing solution after cleaning is completed.
