> Principle of Seam Sealing
When seam tape is heated up, the adhesive on the tape is activated. This activated tape is applied on
the water proof coating or lamination of the fabric seam under pressure. When cooled, a strong bond
is formed between the tape and the seam. This bond is so strong that it will prevent pressurized water
from penetrating the sewn seam. As a result, a water proof seam is produced.
A hot air machine, like AI-007, produces hot air with precisely controlled temperature to directly heat
up the adhesive of seam tape. The heated tape and the fabric are feeding into two oppositely rotating
rollers under pressure called nip rollers. The linear speed of the nip rollers is called sealing speed.
During sealing, hot air is being blown out from the nozzle. The hot air that actually reaches the surface
of the tape is a mixture of hot air from the nozzle and surrounding air, hence the actual temperature
that appeared on the tape is somewhat lower than the nozzle temperature. The farther the distance
between the nozzle and the tape, the higher the percentage of surrounding air becomes. On the other
hand, a higher hot air flow rate will reduce the percentage of surrounding air causing the hot air
temperature appeared on the tape to be higher. So both the nozzle position and hot air flow rate are
very important factors.
So, the major factors that can affect the seam sealing are as follows:
Hot air temperature
Sealing speed
Nozzle air pressure
Air flow rate
Nozzle position
When a consistent product is required, the combination of the above factors have to be set precisely
since their effects towards a proper sealing are all interconnecting.

> Preparation for Installation
Installation must be carried out by authorized personnel. Follow the steps below:
1. Position the machine on a flat surface and allow at least 50cm clearance on both sides as well as
the back side, this is essential for the hot air deflector to work properly and also to allow enough
room for carrying out necessary service and maintenance
2. Adjust the foot stand so that the machine is level and stable.
3. Cut loose all packing cable ties and materials in order to free up all machine movements.
4. Connect the power plug to a suitable outlet with at lease 15A capacity.
5. Locate the air hose supplied with the machine. Connect one end to the inlet of the water filter at
the back side of the machine; connect the other end to a compressed air supply such as air
compressor or central air supply. Make sure the compressed air supply has at least 0.6 Mpa (6 bar)
of pressure and a flow rate of no less than 100L/min.
6. Install the tape dispenser assembly at the top of the machine and align the tape spool at right
angle to the width of the machine. (see diagram below)
7. Install a roll of seam tape with the adhesive side facing the operator (refer to the section on tape
loading).
8. The machine is now ready for operation.
Install tape dispenser assembly

> Control Method
>> Touch Screen Control Panel
Almost all settings and timing control of the machines can be input from the touch screen control
panel. Use you finger tip to touch the parameter to be modified. Switch to different pages to
modify other parameters (refer to section on control menu navigation). The screen has a protective
cover to prevent the surface from damage and scratch, however, avoid using excessive force when
touching the panel.
>> Foot Switch
There are 2 foot pedals for the machine. The design of these pedals is such that they can be
operated either individually or in combination to achieve a number of preset tasks by the operator’s
feet alone. As a result, the operator’s hands are free to manipulate the processing fabric.
Left foot pedal
The left pedal is a multi function pedal. You can use it to raise the upper roller and start sealing
To raise the upper roller - heel back the left foot pedal.
To start sealing - press forward.
Right foot pedal
The right pedal is a simple ON/OFF switch. It performs different function according to the timing
of activation
During idle –jog function that makes the rollers rotate forward without the nozzle coming in.
During sealing –cut function that cuts the tape
While left foot pedal is heel back –perform tape cutting function

The followings are typical menu pages, all of them have names at the top left corner for easy
identification. Right arrow buttons are for navigating in the operation menu group. Down arrow
buttons are for navigating in the support menu group. Please note that page ‘main’is the hub of the
menu network so only this page has navigation buttons for both operation and support menu groups.
