3 Product description
3.1 Components and proper usage
Heating presses are electrical heating devices for use in fabricating (splicing) belting material that
can withstand maximum temperatures of 200°C. Heating presses are used to splice belting material
using pressure and temperature. Depending on the requirement we differentiate between different
designs and type.
The heating press consists of the following components and functional groups:
Functional group
Components
Top part
Pressure beam
Pressure hose
Heating plate with edge cooling bar
Plug-in contact / cable
Bottom part
Pressure beam
Heating plate with edge cooling bar
Plug-in contact / cable
Eye bolts with nuts
Mechanical hold-down bars
3.2 How it works
In the closed heating press pressure and temperature are generated between the top and bottom
part and the electrically heated heating plates when compressed air is supplied; this caused the
melting of the inserted belting material as well as the splicing after a prescribed period (hold-down-
time). Once cooled down, the finished splice has got the physical features required.
For further information on how the heating press functions, see chapter "5 Handling".

4 Preparing the product for usage
Before starting the operation of the tool, the following steps must be carried out each time to ensure
that the tool works properly. Check the following points:
4.1 Transport
The transport / the relocation / the use of the device should be carried out by an appropriate lifting
appliance (regarding the minimum lifting force, please look at chapter “3.3 Technical data“). Prior to
this relocation, the device should be disconnected from the energy supply (electrical current and
compressed air).
The tool may only be transported in cooled-down condition and under observation of the generally
valid safety regulations.
Note:
When transporting, make sure that the heating presses are only transported or stored when they are
closed (This protects the heating surfaces best from damage). The filling of the pressure hose (0,5
bar is sufficient) avoids any unintentional opening of the press during the transport.
Warning
Make sure that the heating press is firmly locked in lifting.
In lifting and transporting the device, please handle particularly with care!
During the transport please do not keep staying under the floating load!
Lift the heating press only at the provided lifting points.
Attention
Do not lift the heating press at the hold-down bars!
Higher tilting danger owing to the irregular weight repartition!
4.2 Position
Heating presses and their components, in particular heating plates, must be only placed on surfaces
that can withstand maximum temperatures of 240°C. Otherwise damage can occur to materials that
are not heat resistant or they will present a fire risk. The surfaces must also be able to withstand the
static load from the weight of the heating presses.
Attention
Risk of burns! Make sure the heating press is always freely accessible and is not covered
up. Should the heating press be covered up, this will present a fire risk.

Operating instruction: I001.1 Edition: 01/2016 14 Subject to alterations.
4.3 Electric installations
The existing mains voltage must be suitable for the tools' operating voltage. The heating plates must
have their own electricity supply according to the information on the type plate.
The connection cables are delivered partial in plug-in form.
4.4 Utilities
Pressure equalizing metal sheets
Shim bars
Textured fabric standard
Silicone fabric no.1
Separating paper
Soft pad 1 mm
Thermometer
All utilities must be cleaned.

Operating instruction: I001.1 Edition: 01/2016 15 Subject to alterations.
4.5 Connection points for the compressed air
The pressing power does not depend on the width of the inserted belt. The required pressing power
should not be exceed or below this value.
The Press is carefully to be closed.
Fill presses equipped with pressure hose only with cleaned and dry compressed air.
Fill pressure hose only, when the press is firmly closed and the hose is properly fitting.
Fill the pressure hose only by means of filling devices provided for this purpose; this makes also
possible the later emptying.
Maximum air pressure: 5 bar
The function in-feed of compressed air is not controlled automatically and must be done from a
stationary compressed air network or a compressor system. The maximum press inlet pressure is not
displayed or monitored on the heating press.
The pressure may only be reduced through the bleeder screw.
For this purpose turn the bleeder screw by half a rotation only!
The safety valve is factory-set to the correct pressing power and may not be modified!
Caution
Risk of injury! Connect the pressure hoses carefully!
Check that compressed air connections work and do not leak.

4.6 Control and limitation of temperature
Several parts of the heating device get extremely hot during operation; therefore touch the press
only at the points intended for.
The temperature must be measured always at the bore of the heating plate.
Other measuring points would falsify the reading.
Only gauged and operative measuring devices may be used!
Attention
The temperature of the heating plates may not exceed 200°C!
In case this temperature is exceeded, the temperature safety fuse would be destroyed
that is built-in for protecting the heating elements. The current supply is then
interrupted.

5 Handling
5.1 General
Heating presses are electrical heating devices for use in fabricating (splicing) belting material that
can withstand maximum temperatures of 200°C.
There are two basic methods of controlling the heating procedure,
a.) An automatic one using a control unit that carries out the heating and cooling phases on special
heating presses automatically after the operator has programmed in and
b.) A manual one where the operator supervises and carries out independently all the cycles.
Note:
When making melting splices always observe the splicing instructions for the belt type to be spliced.
5.2 Inserting the belt into the heating press
1. Prepare the two belt ends according to the required connection (Z-splice, wedged splice etc.).
2. Place the pressure equalizing metal sheet on the bottom part of the press and cover them by
silicone fabric No. 1.
3. The both belt ends must be centrically placed on the pressure equalizing metal sheet (with the
operating side reversed).
4. Place the shim bars (or material of the same thickness) to the left and right next to the ends of
the belt (refer to the following figure).
Note:
Always fold out the areas to be pressed to the full width. If the belting
material is a) narrower than the area to be pressed, (so that the press
do not flexing) extra pieces in the same thickness or several shim bars
of the corresponding width must also be inserted
5. Please entirely push together and mark the Z-splice (Fig. 1).
6. Place the hold-down bars and slightly tighten them.
7. Centre and align the belt (Fig. 2), adjust the distance between the
two belt ends according to the instructions for the respective belt type
(belts mostly about 5 mm).
8. Evenly tighten the hold-down bars.

Operating instruction: I001.1 Edition: 01/2016 18 Subject to alterations.
9. If necessary etc., cover the splice with additional material (PVC-Z-foil,
PU-Z-foil) (Fig. 3).
10. Depending on the belt type, place the prescribed cover material
(silicone embossing mat, separating paper, textured fabric fine etc.)
(Fig. 4).
11. Cover the splice with the top pressure equalizing metal sheet.
12. Place the top heating plate.
13. Place the top pressure beam with pressure hose.
5.3 Closing the heating press
The centering pin must slide into the centering bore.
1. Slightly tighten nut by hand.
2. Only then fill the pressure hose with air.
(max. 5 bar)
Note:
The feeding of compressed air is not automatically
controlled and must be done in form of a stationary
compressed air network or a compressor system.
A pressure display does not exist!
Warning
Risk of injury! The permitted maximum air pressure for generating the pressing force is 5
bars. If you exceed this maximum figure, the device can burst!

5.5 Connecting the heating press to the mains and heating the splice
1. Connect the heating press to the mains.
Attention
Risk of fire or damage because of overload to the electricity supply. The electricity supply
for the heating plate must be separated from the mains according to the indications
mentioned on the type plate! If necessary, make sure the heating press has a separate
electricity supply.
2. Observe the heating temperature using the thermometer included and put it in the
measurement drill holes provided.
3. As soon as the heating temperature required has been reached, disconnect the heating press
from the mains by pulling out the plug on the heating plates. The data sheet for the belt
provides information on the heating temperature and hold-down time.
Make sure the heating plates are not heated above 200°C as this will destroy the in-built melt fuse
or the heating resistance. You can automatically regulate the temperature using a control unit.
Warning
Risk of injury from burns. The heating plates can get very hot during heating (up to
200°C) Touching them without any protection will mean burns.
5.6 Cooling the splice
1. Only let in cooling water after the heating procedure has been completed. Only use clean
water.
2. Cool the heating press till the heating plates has reached a temperature of approx. 40°C.
5.7 Removing the belt from the heating press
1. Please empty the pressure hose.
Note:
Empty the pressure hose only after the heating press has cooled down!
2. Please open the heating press and take off the belt.
3. If necessary, clean the edges and the surface of the belt from excess material.
The belt is prepared.
4. After use, clean the heating press.
