(4) Purpose of Machine and Installation
1) Most waterproof textiles are made of performance fabric which passes through
air but blocks water. However, water may pass through needle holes which are
created during sewing as shown in <Figure B> below.
[Figure A] [Figure B]
[Figure C]
Properly Sealed No Air Allowed
6
2) In order to prevent water leak through the seam, this machine seals the seam
using hot wind as shown in <Figure A> above.
3) If the seam is properly sealed, there should be no air on the tape sealing space
as shown in <Figure C> below. Air could be created due to machine speed,
temperature, or pressure. The fabric and tape should be checked as well.

4) Installation
- Place machine keeping 50cm distance from walls and lock the wheels with locking
lever on the left wheel.
5) Air and Power Connection
ⓐ Air pressure: 5kg/cm2 - 6kg/cm2 / Compressor capacity for 1 set: 3HP
(NOTICE) Under low pressure, warning alarm may not go off and machine
won’t be operated.
ⓑ Power Connection
Power is connected by 1P 220V.
For both 50Hz and 60Hz
If the voltage is lower than 210V
or higher than 240V,
stop the operation.
7

(5) Preliminary Check before Operation
1) Check if air filter gauge pressure exceeds 5kg/cm2 (FT1 in Figure 1 below)
Adjust the pressure to over 5kg/cm2 with adjusting lever
If lower than 4kg/cm2, warning alert goes off and machine stops.
2) Check filter air tank and remove moisture if any
. (FT2 in Figure 1)
3) Check if nozzle air pressure exceeds 1kg/cm2.
If it doesn’t, do the adjustment (RG 1)
If the pressure is lower than 0.8kg/cm2,
nozzle temperature doesn’t go up any more.
4) Set the tape.
(See Tape Setting in page 14)
5) Switch on the power.
(Power SW1)
6) Switch on the nozzle temperature.
(See Temperature Input Method in page 25)
7) Switch on upper roller heater.
(See Temperature Input Method in page 25)
For temperature rise in upper roller,
it takes about 10 minutes.
8) Set proper speed
Type of TapeSpeedTemperature* Adjust the speed depending on the type of tape and fabric.
* Under over 4m/min, 3-layer tape becomes the cause of water penetration

* Adjust the speed depending on the type
of tape and fabric.
* Under over 4m/min, 3-layer tape
becomes the cause of water penetration
1) In order to get high-quality products, the selection of type and width
of nozzle is important (See Type of Nozzle in page 13)
2) For this machine, compressor capacity should be 3HP and 1KW
of electricity (220V) is needed.(compressor capacity excluded)
m{Z

(6) Pedal S/W Operation
ⓐ UP / DOWN of Upper Roller (S/W “B”)
1) Whenever Pedal S/W B in [Figure 1] is stepped on, the upper roller moves
up and down.
S/W “B” (Upper rollr part)
[Figure 1]
ⓑ Start Operation (S/W “A”)
1) If Pedal S/W A in [Figure 1] is slightly stepped on,
roller revolves and a nozzle moves.
2) If it’s hit on hard, the tape is cut off and a nozzle stays in a roller for some time
and returns to an original place. Then, the upper roller goes up after revolving
for some time. Then, tape keeps going down up to the next work position.
S/W “A” (Nozzle part)
ⓒ Finishing Up (Switch Off)
1) Switch off nozzle temperature and roller temperature
2) If the nozzle temperature is lower than 70℃, remove air. Switch off power.
3) If air is removed before nozzle temperature falls, a heater may break down.

(7) Adjusting UP / DOWN Speed of Upper Roller
Before adjusting the speed,
① check if air supply pressure in foot board filter exceeds 5kg/cm2. If it doesn’t,
the adjusting job may not be done properly. (Gauge pressure of FT1 in Figure 3)
② fully turn pressure adjusting lever in upper roller pressure press (RG2 in Figure 3)
to the right. After checking the description above, slowly turn J1 and J2 in [Figure 1]
and set proper speed (to the level that no tremble is detected in machine).
J1 is adjusted during UP while J2 is adjusted during DOWN.

(8) Nozzle Speed Control
Adjust the speed by turning H2 and H1 in [Figure 1] above. H1 adjusts the speed
when a nozzle moves toward roller while H2 adjusts the speed when a nozzles moves
from roller to the outsides.
If a nozzle moves too fast, a heater could break down.
* Speed Adjusting Lever
After adjusting the speed by turning A2 bolt in [Figure 2],
A2 movement should be prevented by A1 nut.

(9) Upper Roller Stroke Control (Figure 5)
Stroke needs to be adjusted depending on type of fabric and tape.
* In an adjustment of stroke, the upper roller should face upward for easy adjustment.
① In case of thin fabric or tape, be careful not to damage the tape.
② In case of thick fabric or tape, it should be adjusted
until a roller is slightly crushed for water penetration effect.
③ If a roller is crushed too much, it could be easily damaged. Therefore, it should be
adjusted enough for the fabric not to be slipped out even if it’s strongly pulled out.
At the same time, the upper roller pressure should be adjusted. (3~5kg/cm2)
(10) Upper Roller Pressure Control
For the upper roller pressure, there are upper roller pressure gauge on the panel
and adjusting regulator.
Adjust the pressure by turning RG1 in Figure 4 and checking RG2 gauge.

(12) Nozzle Angle Control (Figure 6)
In order to adjust nozzle angle, make sure that the temperature is low.
In case fabric is severely crushed (2-layer) or burnt (3-layer) when sealed with
seam sealing tape, the nozzle angle should be adjusted.
1) Once the heat cools off, slightly loosen bolt F and tightly fasten bolt with
(+) screw driver holding nozzle with spanner.
2) After nozzle is heated, bolt F can be loosened. Then, nozzle angle can change.
Then, screw bolt F again holding the nozzle with spanner (Keep watching out HEAT)
[Figure 6] [Figure 7] [Figure 8]
* Nozzle Cleaning
If nut G is turned to the left once a nozzle is cooled off, the nozzle is separated
from heater housing. Mildly stir nozzle upside down and remove foreign substance
(glass powder) in a nozzle. If nozzle is blocked, the sealing would not be properly done.
Then, a heater problem may be followed.
If nut G in Figure 7 is turned while a nozzle is heated, G thread could be spoiled.
(13) Type of Nozzle (Figure 8)
As shown in Figure 8, a type of nozzle is as follows:
2 Layer – PU, PVC tape used
3 Layer – In order to prevent fabric burning, it’s designed for heat to be dispersed.
Used in 3-layer fabric
Width of nozzle: A nozzle should be 1-2mm wider than tape.
