3 Product Description
3.1 Components and proper usage
Heating presses are electrical heating units for use in fabricating (splicing) belting material that can
withstand maximum temperatures of 110°C. Heating presses are used to splice belting material
endless using pressure and temperature. Depending on the requirement we differentiate between
different designs and types.
The heating press consists of the following components and functional groups:
3.2 How it works
Pressure and temperature is generated in the closed heating press between the top part with the
electrically heating plate and the bottom part with the pressure equalizing plate under pressure and
temperature, this causes the belting material inserted to heat up a prescribed period (hold down
time) and after adding splicing accessories to bond. Once it is finished and cooled down the splice
has the physical features required.
You can find more information on how the heating press works in the chapter „5 Handling“.

5 Handling
5.1 General; proper usage
Heating presses are electrical heating units for use in fabricating (splicing) belting material that can
withstand maximum temperatures of 110°C.
In this section we will deal with the heating procedure where the operators monitor and carry out all
the steps themselves.
With heating presses of the HPS … series you can only make bonded splices. When making bonded
splices, always observe the splicing instructions for the belt type to be spliced.
Note:
You can ask the manufacturer to send you splicing instructions for the belt types you require.
5.2 Heating up the top part of the press (heating plate)
Before each heating procedure take off the top part of the press first and heat it to its target
temperature. The thermostat must switch off at a target temperature of 110°C. Check the
thermostat works properly using a thermometer as follows:
1. Put the thermometer in the appropriate drill hole.
The thermometer must then display 110°C.
After using the heating press several times (about 10 times) check that the thermometer shows the
correct temperature.
2. If the thermometer is working properly and the target temperature is not shown, you must
adjust the thermostat so that the red control light switches off at 110°C.
Note:
For adjusting the thermostat use an insulated screwdriver and put this in the marked drill hole on
the top of the body (see chapter “4.5 Thermostat”).

Operating instruction: C032 / 0842 / 0844 Edition: 01/2015 16 Subject to alterations.
5.3 Inserting the ends of the splice in the heating press
When making bonding splices always observe the splicing instructions for the belt type to be spliced.
A successful heating procedure depends on the heating plate at the top part of the press reaching
the target temperature of 110°C. It is also important that you observe the correct order of the
intermediate layers when inserting the ends of the splice in the heating press (specific to belt type).
1. Line the bottom part of the press with heat-resistant foil.
2. Centre the prepared ends of the splice and exactly on top of one another.
3. Align the ends of the splice and fix them with the clamping rails by tighten the star grips.
4. Loosen the both knurled screws of the removable hold-
down bar.
5. Take out the prepared end of the splice with the removable hold-down bar and the clamping
rail and put it next to the heating press.
5.4 Coating the ends of the splice
Before you can heat the splice, the ends of the splice, depending on the belt type, must be coated
with a splicing accessory (adhesive). The end of the splice to be coated should now be tensioned in
the hold-down bar and next to the bottom part of the press.
1. Coat the end of the splice with adhesive (see splicing instructions).
2. Put the hold-down bar with the prepared end of the splice in the bottom part of the press
again.
3. Screw on the hold-down bar with the prepared end of the splice into the bottom part of the
press (tighten the knurled screw).
4. Place the prepared ends of the splice according to the splicing instructions exactly on top of one
another.
5. Cover the splice with a intermediate layer or heat resistant foil.
6. Now put a piece of soft pad 2 mm on the splice and cover everything with the pressure
equalizing metal sheet.
7. Put the pre-heated top of the press with the heating plate on.

Operating instruction: C032 / 0842 / 0844 Edition: 01/2015 17 Subject to alterations.
5.5 Closing the heating press
Close the heating press very carefully.
The torque required depends on the width of the heating plate and the belting material.
1. Tighten the nuts on the tensioning bolts with a torque wrench evenly.
Torque by SB-HP-180/750: approx. 350 NM (254 ftlb)
Torque by SB-HP-180/1000: approx. 500 NM (362 ftlb)
2. Make sure the pressure and the heating plate are parallel to one another.
Note:
If the belting material is (a) narrower than the area to be pressed, extra pieces of belting
material in the same thickness (b) must also be inserted to stop the heating press buckling (see
figure on the right).
5.6 Heating the splice
The target temperature of 110°C must now be held for a prescribed period.
Warning
Risk of injury from burns. The heating plates can get very hot during heating. Touching
them without any protection will mean burns.
1. Observe the heating temperature as stated in the splicing instructions with a suitable
thermometer that you must stick in the drill hole provided.
2. Heat the splice according to the instructions on hold-down time as outlined in the splicing
instructions.
3. Control the hold-down time by using a timer.
4. Switch off the heating press after the hold down time has elapsed by disconnecting from the
mains (pull the plug).

Operating instruction: C032 / 0842 / 0844 Edition: 01/2015 18 Subject to alterations.
5.7 Connecting the water cooling system and cooling the splice
The splice can now be cooled The cooling procedure is always carried out for both the heating press
and the splice inserted. If possible (depending on the type of heating press), the cooling procedure
can be accelerated by a water cooling system.
Warning
Risk of injury! Connect the cooling hoses carefully to the tool. Leaking water or steam
can be leading to burns.
Check connection points for the cooling system work and do not leak.
1. Make sure no more water is in the cooling system.
2. Connect the cooling hoses on the rapid action couplings for the water cooling system at the top
part of the press.
Note:
Do not let in the cooling water until the heating procedure has been completed. Only use clean
water.
The cooling water is conducted using a submerged pump from a mobile cooling water container.
If the water in the cooling container has heated up to such an extent that the pre-set cooling
temperature cannot be reached, the water must be exchanged. This is only necessary in larger
presses or several successive heating procedures.
The cooling procedure can be continued directly after the cooling water has been exchanged.
3. Cool the heating press with the inserted splice till the temperature has reached approx. 40°C.
4. Open the heating press and take out the belt.
5. Straighten up the splice's edges by cutting off belting material that pokes out.

6 Maintenance work
Before operating the tool, the following maintenance work must be carried out each time to ensure
that the tool works properly. If damage is established during maintenance that cannot be put right
on site, the tool must no longer be used and must be sent for repair to the manufacturer.
Check the following each time before use:
Mains plug, leads and body for damage
Heating plates for residues (if necessary remove these)
Check star grip screws and nuts on the tensioning bolts sit properly, lubricate as needed (the
threads must be easy to use)
That the tool is generally clean
That drill holes for the thermometer and thermostat are clean
Pressure equalizing metal sheet / plate for smoothness and cleanliness
Screws for properly sit
That water connections points (cooling systems) do not leak
Check after using several times:
Surfaces of heating plates have not deflected.
Test the heating plates for bowing in cold and in warm condition by means of a straight edge. If
the plates are bowing by more than 0,3 mm, the plates must be returned to our factory for
overhaul.
Warning
Risk of injury! The heating plates get very hot during the heating procedure, the
operator risks burns.
Check every twelve months:
According to VDE-guideline 0701/0702 or the appropriate electrical engineering norms in the
individual country, electrical tools must be checked every twelve months in each company.
