10 Heat sealing
The machine may only be operated by properly instructed personnel. The opera-
ting personnel must make sure that only authorised persons are in the danger
zone of the machine.
In particular for production, in addition to the input menu (see Chapter 11 Input), the „heat
sealing“ mode is available, in which, irrespective of the program selected and the machine
status, all functions and settings relevant for the sealing operation are shown on the display.
With the program selection function, following production types can be selected in the "heat
sealing" mode, see Chapter 9.02 Selecting the production type:
Manual heat sealing, see Chapter 10.02
Programmed heat sealing with individual programs, see Chapter 10.04
Programmed heat sealing with sequences, see Chapter 10.06
10.01 Heat sealing principle
To achieve optimum sealing results, certain conditions must be fulfi lled with regard to mate-
rial and machine setting.
The material must:
- be heat-sealable, and
- suitable for being processed by the machine with regard to thickness and structure.
In the seam area, the material to be heat sealed must be clean and free from separating
agents, such as e.g. oil or silicone.
The basic conditions depending on the sealing device are:
- correct working temperature of the hot wedge or hot air temperature (sealing temperature);
- correct contact pressure of the hot wedge and the correct position of the hot air nozzle;
- correct setting for the hot air volume;
- correct choice of feed rollers (silicone or steel);
- optimum pressure of the feed rollers on the material being sealed (roller pressure);
- correct distance between the feed rollers and
- correct sealing speed (feed stroke).
All the settings of the heat-sealing device are principally dependent on the ma-
terial being sealed and the ambient temperature. Due to the infl uence of the in-
dividual operating parameter on each other, it is only possible to determine the
optimum setting values by carrying out test sealing operations.

Standard pedal functions (see chapter 7.04)
+2
It may become necessary to reduce the welding speed for a short time during the welding
process (e.g. when passing transverse seams). For this purpose, a reduced welding speed is
-1
assigned to pedal setting +1 by way of parameter "POS1speed".
Call up parameter "POS1speed" (see chapter 13.14 "Parameter Settings")
The input value determines the reduced speed of pedal level +1 as a percentage value of
the current welding speed.

Input
11 .05.02 Function "HEATOUTDELAY"
The tilt out time of the heating element is set within the braking phase by way of parameter
"HEATOUTDELAY".
This will ensure that the welding seam will be securely closed within the braking range.
Call up parameter "HEATOUTDELAY" (see chapter 13.14 "Parameter Settings")
The input value determines the tilt out time of the heating element as a percentage value of
the current braking range.
In the following diagram, the welding speed is displayed in blue, the tilt-out signal (Y4) in turquoise, and the response signal (E4) in magenta.
The parameter "HEATOUTDELAY" is set to 80 %.
Welding speed is 10 m/min and the deceleration is 0.35 m/s2 .
This results in a braking range of 476 ms.
The tilt-out signal (Y4) is triggered after 380 ms (= 80% of 476 ms), and the mechanical tilt-
out movement is completed at the end of the braking range.
476ms
80
Page 81
Input
Using a percentage value for the parameter "HEATOUTSELAY" ensures that the conditions
are virtually independent of the welding speed, as the following diagram documents
(welding speed 5 m/men).

.01 Notes on adjustment
All following adjustments are based on a fully assembled machine and may only be carried
out by expert staff trained for this purpose.
Machine covers, which have to be removed and replaced to carry out checks and adjust-
ments, are not mentioned in the text.
The order of the following chapters corresponds to the most logical work sequence for ma-
chines which have to be completely adjusted. If only specifi c individual work steps are
carried out, both the preceding and following chapters must be observed.
Screws, nuts indicated in brackets ( ) are fastenings for machine parts, which must be loo-
sened before adjustment and tightened again afterwards.
Unless stated otherwise, during all adjustment work the machine
must be disconnected from the electric and pneumatic power supply!
Danger of injury if the machine is started accidentally!
Before all adjustment work switch the machine off and let it cool down!
Danger of burns if the hot-air nozzle is touched!
