2.1 LOADING THE SHRINK FILM
When the fi lm is properly loaded the motorized fi lm unwind assembly provides fi lm as required
by the packing process.
2.1.1 Film Loading Micro-switch and Contact Wheel
The micro switch located above the left side of the dancer assembly controls the operation of the
fi lm delivery motor. When the actuator wheel on the side of the arm touches the micro-switch,
the fi lm delivery motor starts running. When the fi lm pressure relaxes, the arm lowers, the
actuator wheel no longer touches the micro-switch, and the motor stops. The actuator should just
slightly touch the micro-switch.

Section 2. General Information
SLCT-FAL5645 Sealing Machine
2.1.3.1 Film Sealing
Before operating the system, check to ensure that the seal wires and upper jaws are clean.
Any residual fi lm caught on or between the wires and the ceramic beads can cause poor seals.
The lower beds should also be kept in good condition. Over time the Tefl on tapes may show
impressions from the wire and some discoloration, this is normal, but burned or blackened tapes
should be replaced. This could be an indication of too much pressure or uneven pressure.
Contact between the sealing blade and the sealing base can be checked as follows:
1. Put a white paper between the sealing blade and base.
2. Manually operate the sealing and cutting process once to see if the force of the sealing and
cutting action is even on the white paper.
3. If it is uneven, loosen the lock nuts and turn the adjusting screws. (Caution this adjustment
must be made with the machine power off and the assembly cooled down.)
To prevent injury, product crushing or machine damage the jaw is equipped with several safeties
that will stop the machine operation if a product or other object is inside the sealing area when
the sealing blade lowers.
The operation of the jaw safety circuit should be verifi ed at least once per day. The jaw safety
circuit is designed to reopen the jaws immediately whenever the jaws contact an object upon
closing. The test requires attempting to make a seal with a rubber test object between the jaws.
When functioning properly, the jaw safety circuit will force the machine into an Emergency Stop
state upon contact with the test object.
2.2.1 Jaw safety Verifi cation Test
1. Ensure that all guards are in place. All doors and hoods must be closed.
2. Connect the compressed air supply for the machine.
3. Power up the machine.
4. Press the E-STOP button.
5. Test object should be resilient. Preferably a spare piece seal bed material (3/8” thick silicone
rubber). Place the test object on the conveyor belt between the seal jaws.
6. Release the E-STOP button by twisting clockwise.
7. Put the machine into a READY state by pressing the READY button (Blue).
8. Perform the test by pressing the manual seal button. The button must be held down until the
jaws close completely.
• PASS INDICATION: Jaws close and then immediately reopen; the READY light Flashes.
• FAIL INDICATION: Jaws do not reopen immediately and/or READY light remains on.
9. Repeat Steps 4-8 several times with the rubber object at different points along the entire length
of each seal jaw to ensure the integrity of the Jaw Safety Circuit.

Adjust Actuator
Figure 2–6 Safety Actuator
If the jaw safety does not work properly: Loosen the top actuator screw and raise or lower it
to allow the sensor to detect the packing product quickly. The distance between the two touch
screws should not be too long, otherwise, the sealing blade will alarm and stop operation before
completing the sealing and cutting action.
2.3 REMOVING THE WASTE FILM (SELVAGE)
The fi lm trimmed from the side during the packing process is called selvage. Selvage is collected
on a wheel located in a compartment at the front of the machine. Refer to Figure 2-7 and follow
the next procedure to remove the waste fi lm that has accumulated on the selvage winder.
1. Open the door to access the selvage winder.
2. Loosen the wheel lock on the front of the wheel, and remove the guide plate.
3. Remove the waste fi lm,
4. Replace the guide plate and tighten the locking cap.
5. Run out some fi lm and re feed the selvage to the wheel. If the wheel slips during the
receiving process, tighten the locking nut a little bit to increase the friction of the selvage
receiving reel
This section details information about installing and adjusting the sealing machine.
Before machine delivery, the machine has already been precisely checked and tuned. “Do
not” change the setting unless it is necessary. However, trained operators are allowed to make
adjustments to some of the necessary settings in order to pack different dimensions of the
packing products.

1. Start the conveyor.
2. Check that the belt is tracking at the center of the bed. If not, follow the adjustment procedure
on Page 2-5 to adjust the belt.
3. Select the appropriate shrink fi lm:
Width of shrink fi lm = W (Product Width) + H (Product Height) + 5” ~ 7” (depends on the
height of the packing product).
4. Adjust the infeed conveyor Height (see Figure 3–4): Rotate the conveyor adjusting wheel to
adjust the height of the triangular plate. The correct position is about 1/2 H (Product Height)
+ 5~10mm.
5. Adjust of the infeed conveyor relative to the product guide (Figure 3-4)by placing a product
on the belt and then squeezing the handle on the front of conveyor unit. This will enable
movement of the conveyor unit to the appropriate width which is W (Product Width) plus
one-third of the product height.

9. After the sealer reaches the set temperature, press the Manual operation button once, the
Sealer will move once, and jaws will remain open.
10. Turn on the conveyor, and place a product on the infeed conveyor. The machine should
advance fi lm and cycle the sealer once. The wrapped product will exit the machine.
11. Continue to run the fi lm feed, while pulling the selvage end of the fi lm until the selvage can
be wound 2~3 times on the receiving reel (Figure
process automatically.
15. The best rear extra fi lm length (B of Figure 3–9), is 1/2 H between the product and the rear
seal. Adjust the
conveyor time setting on switch #13 in Figure 3-1 to increase the fi lm length
at the rear of the package.
16. Different shrink fi lms have different sealing time (Typically 0.3~0.6 seconds). The fi lm
must be sealed and cut completely and steadily without holes. Poor fi lm cutting may be
caused by overheating on the sealing process. Adjusting the sealing dwell time or the sealing
temperature should eliminate this issue.
17. When the sealing and cutting line is good, the adjustment process is fi nished.
3.4 FUNCTIONS
• The machine includes a warning system, and a safety function.
• The sealing and cutting process can operate continuously.
• Simple machine operation can match various sizes of packing products.
• PLC and optical sensor control are applied on this machine.
• Two types of optical sensors (Horizontal type and Vertical type): Horizontal type optical
sensors (as shown in
Figure 3–10) are applied on packing square or rectangular product.
It includes a wait function. The Vertical optical sensor is mostly used for packing thinner
products, but there is no wait function on this sensor.
• According the characteristics of the product, there are two types of the sensor mode selection:
Standard type and point-to-point compensation type (as shown on
• When the products are in rectangular or square shape, Standard sensor mode should be
applied.
• If the packing products are an irregular shape or transparent, then the Point-to-point
Compensation sensor mode should be applied and the Conveying Time switch adjusted to
control the fi lm length.

18. The sealing blade of this machine can be used on the POF and PE Shrink Film. When using
on the PE Shrink Film, the sealing blade must be covered by heat-resisted adhesive tape to
prevent the blade from directly contacting the PE fi lm.
The machine employs an infeed conveyor and a discharge conveyor mounted at the same
elevation to convey product through the machine. The upper seal jaws and lower seal beds
both pivot such that they meet at the center line of the package when a seal is being made. The
infeed conveyor carries product through the fi lm inverting head where it is surrounded with
plastic shrink fi lm supplied by a powered fi lm unwind assembly. When the product reaches
the proper position in the sealing area, the conveyors stop and the Sealer cycles, making a seal
and cutting fi lm on two edges of the package. After sealing is completed, the seal jaws open
and the discharge conveyor carries the product out of the machine while the infeed conveyor
simultaneously delivers the next product to the sealing area.
