3. SAFETY
Your vulcanizer has been designed to provide safe, efficient, trouble-free service for many years. Component
design and material selection have been carefully considered to ensure operator safety and our manufacturing
procedures provide a consistent, high-quality product.
The material that is presented in this operating manual has been compiled to provide direction for operating
personnel so that the maximum effectiveness of the vulcanizer can be achieved and so that there is a complete
understanding of correct operating procedures.
PLEASE READ CAREFULLY
The following safety precautions should be read carefully and understood thoroughly before you set-up or
operate your vulcanizer. Failure to follow these precautions may result in personal injury and/or equipment
damage. All operating personnel should be trained in the proper method of handling and operating the
vulcanizer.
The risks associated with operating the vulcanizer are identified throughout this manual with pictograms.
3.1. Definition of Pictograms
Safety Alert
Crushing Hazard
Burning Hazard
Electrical Hazard
3.1.1. Safety Alert
1. Never leave the vulcanizer operating while unattended.
2. Ensure that all components are correctly assembled before pressurizing the vulcanizer.
3. Ensure correct traverse bar layout is made using the templates supplied with the press.
4. Ensure entire platen surface is filled so that traverse bars and tie bolts are loaded evenly and to prevent
platen damage.
5. Always use the restraining equipment supplied. The restraining bars and safety pins must be in use to
reduce the hazards that might result in the event of a bolt failure.
6. Visually inspect all load-bearing components for cracking or deformation before each use. Replace any
damaged components.
7. The tie bolts must be tightened evenly, HAND TIGHT ONLY.
8. Do not lean against or over top of the vulcanizer during operation. Since high stress levels are resident in
the frame and assembly members during operation, component failure can result in a sudden movement of
components. The restraining system, when properly installed, will prevent parts from being projected
upward or outward.
9. Always use an ALMEX pressure controller. Do not exceed the maximum operating pressure of the
vulcanizer. Do not connect the vulcanizer to a continuous pressure supply. In the event of component
failure, it is important for the pressure to drop to a safe level. Do not tamper with the pressure relief valve.
It is factory preset to prevent the vulcanizer from operating at unsafe pressures.
3.1.2. Crushing Hazard
1. There is a crushing hazard when assembling the vulcanizer components.

SVP INSTRUCTION MANUAL Page 6
SHAW-ALMEX INDUSTRIES LIMITED 49909-010
Jun 2017
3.1.3. Hot Surface, Burning Hazard
1. The platen surfaces typically operate at or above 300F (150C). Touching these surfaces will result in a
burn.
2. The cooling water will discharge from the platen initially as steam creating a burning hazard. Ensure the
cooling water discharge is not directed at any person or injury could result.
3. Always use an Almex temperature controller when operating the vulcanizer and never leave the vulcanizer
operating while unattended. Improper use or component failure could result in the vulcanizer overheating.
3.1.4. Electrical Hazard
1. A qualified electrician should perform all maintenance of the electrical components of the vulcanizer.
2. All of the electrical components contain live circuits. Do not open or service any of the electrical equipment
without disconnecting the main power supply.
3. Incorrect voltage and phase may result in component damage and create a fire hazard.
4. Equipment power supplies must be properly grounded or a severe shocking hazard may result.
5. Avoid using equipment in wet surroundings or a severe shocking hazard may result.
6. If any cables or connectors are damaged, they must be replaced or a fire and shock hazard may result.
3.2. Limitation of use
This equipment has been designed to vulcanize conveyor belts. The process of vulcanizing is done by applying a
combination of heat and pressure on the product for a certain period of time.
The SVP vulcanizer may operate at up to 200 psi [1380 kPa]. Refer to the rating label on the traverse bar for the
maximum pressure of the specific unit. The press is designed for connection to an ALMEX pressure control unit
that is generally supplied complete with a pressure hose. A continuous pressure supply must not be connected to
the press.
The recommended maximum operating temperature is 325 F (165 C) for long life of the heating element and
platen insulation. The press is designed for connection to an ALMEX temperature control panel that is supplied
complete with platen electrical cables.
Hoses have been provided to connect a cooling supply to the press.
Never leave the vulcanizer operating while unattended. Other use is not allowed without the written permission
of Shaw-Almex.
3.3. Hazardous Materials and Products
The cooling water may discharge from the platen initially as steam creating a burning hazard. Ensure the cooling
water discharge is not directed at any person or injury could result.
There could be hazards associated with the vulcanizing materials. Consult the splicing material specification for
details.
3.4. Safe Handling
Handling the machine does present some residual hazard. The weight of the components is marked on the
components. Hoisting equipment may be needed to position the platens and traverse bars in place. Approved
hoisting slings will be required.
Wear protective footwear when handling the press.
Connection of cables and hoses must be made in such a way that no tripping hazard is created.

4. ASSEMBLY
4.1. Dimensions
4.2. Splicing Principals
There are two essential requirements for perfect splicing of conveyor belting; Uniform Pressure and a controlled
Uniform Temperature. Both of these requirements are satisfied in the ALMEX Vulcanizer.
Uniform Pressure:
Full platen size pressure ‘bag’ applies uniform pressure over the entire platen area.
Important: This unique platen requires support over its entire area or permanent distortion of the platen may
occur. Fill any unused portion of the platen area with scrap belting or shims the same thickness as the belting
being cured.
Uniform Temperature:
The heating element is a silicone rubber ‘blanket’ which covers the total platen surface.
4.3. Unpacking
Carefully unpack vulcanizer from the crate and inspect for damage. Any damages or shortages should be
reported to the carrier and / or Shaw-Almex Industries Limited.

1. Remove idlers from the conveyor to provide space
for assembly of the vulcanizer. Use the set up
template and the General Arrangement drawing to
judge the distance.
2. With the ends of the conveyor belt laid back out of
the way, locate the template at the splice location.
The templates ensure the correct traverse bar
spacing and the joiner angles ensure the correct
bias angle. See Figure 4 Templates.
3. Position the traverse bars on the template. If the
end of the traverse bar is relieved for the tie bolt,
make sure the relief is on the top. See Figure 5
Traverse Bars.
Safety: Use safety slings for moving components
too heavy to be moved manually.
4. Install the lower restraining bars. With the gauge
pin removed from one end, slide the bar through
each traverse bar and install the gauge pin. Both
gauge pins should be approximately 3/4” (18 mm)
from the side of the outer traverse bars.
5. Install the platen carrying handles or hoist rings
into the threaded holes on the edge of the lower
platen hand tight. See Figure 6 Bottom Platen and
Handles.
6. Lift the platen onto the lower bars. Make sure the
platen is centered in both directions over the bars.
Safety: Do not use the platen handle to lift the
platen overhead.
7. Remove the platen handles because they will cause
cold spots on the platen.
8. If the orientation of the platens causes the electrical
and cooling fittings to be underneath the belt,
install the cooling hoses and platen cable now.
9. Prepare the splice on the bottom platen. It is good
practice to lay plywood or some other material on
the bottom platen while preparing the splice to
prevent damage to the platen surface.
Tip: A plywood deck can be built up around the platen
to increase the size of the worktable.
Caution: This unique platen requires support over its
entire area or permanent distortion of the platen may
occur. Fill any unused portion of the platen area with
scrap belting or shims the same thickness as the belting
being cured.
10. Install the cooling hoses on the bottom platens at
this time. It can be difficult to install the cooling
fittings after the edge irons and top platens are in
position.

11. When using edge irons, place them on the lower
platen on each side of the belt. See Figure 7 Belt
and Edge Irons.
Tip: The edge irons should be slightly thinner (0.015”,
0.5 mm) than the belt.
12. Using the platen carrying handles, lift the top
platen into position over the splice. Ensure the
platen cable connections are at the same end and
the upper platen and lower platen are aligned. See
Figure 8 Top Platen.
Safety: Do not use the platen handle to lift the
platen overhead.
13. Remove the platen handles.
14. Position the pressure bag and bag plate over the top
platen. Locate the hose coupler at the most
convenient side for connection to the airline or fluid
pressure pump. Try to position the bag so the coupler
is on the opposite side to the electrical connection.
See Figure 10 Pressure Bag and Bag Plate.
15. Remove the dust cap from the electrical connectors
and install the platen cable plug. The pin
configuration allows the plug to be installed only one
way. See Figure 9 Platen Connection
•Rotate latches open.
•Push the plug firmly into the socket.
•Rotate latches closed to hold plug in place.
Tip: The two ends of the SVP –T4 platen cables can be
connected during storage and transport to protect the
contact pins from dirt, moisture and damage. See Figure
11 Platen Cable.
Safety: Always be sure the power supply is OFF
before connecting or disconnecting the platen cables.
16. Position the top traverse bars on the pressure bag
plate. The top bars must be aligned with the lower
bars and parallel across the top of the press at both
ends of the bars. See Figure 12.
17. Install the tie bolts. The square nut must fit within
the nut retaining lugs on the traverse bars. Tighten
the shank of the tie bolt BY HAND ONLY until
the square nuts bear flat on the lugs.
Caution: Under no circumstances should a wrench be
used to tighten the tie bolts when assembling the
unit. If nuts do not turn freely by hand, inspect and
repair or replace the bolt.

18. Install the restraining bars. With the gauge pin
removed from one end, slide the bar through each
traverse bar and install the gauge pin. Both gauge
pins should be approximately 3/4” (18 mm) from
the side of the outer traverse bars.
19. Install the bolt retaining pins through the holes in
the remaining upper and lower bars.
Safety: The restraining bars, gauge pins, and
bolt retaining pins are safety components. When used
together this feature will protect against hazards that
might result in the event of a bolt failure.
20. Adjust the edge irons.
21. Position the temperature controls and pressure
controls at the splice location.
22. Make electrical, pressure and cooling connections as shown on the General Arrangement drawing at the
back of this manual. If unfamiliar with this procedure, refer to the manuals for the temperature controller
and the pressure controller.
23. Connect the top and bottom platen electrical cables to the temperature controller and connect controller to
power supply. See temperature controller manual.
24. Connect the top and bottom platen cooling supply and drain hoses.
4.6. Assembly of Multiple Platens
Multiple platen Sectional Vulcanizers are designed so the platens can be placed side by side to make a larger
platen area. The assembly procedure is the same as described above, with the following additions.
1. The template will be in more than one section on arrangements over 96” (2.4 m).
2. The restraining bar will be in more than one section
on arrangements over 96” (2.4 m). Join the
restraining bar sections using the union as shown.
The union is properly installed when the spring
plunger is engaged in the countersunk hole. Install
the lower restraining bars as the traverse bars are
moved into position because it can become difficult
if the traverse bars are not at the same height.
3. Install the lower platens on the lower bars with the
edges tight together.
Tip: It is good practice to use two 1/8 inch (3 mm) steel
plates the same size as the total platen area when
splicing with multiple platens. One plate is used on
top of the lower platens and the other plate is used
on top of the belt (below the upper platens). The
steel plates ensure that no rubber flows between the platen joint. Always try to locate the pressure bags so
that the joint between bags does not coincide with the joint between platens.
4. Install the upper platens aligned with the lower platens and with the edges tight together. The insulation is
made smaller than the platen so the platen edges come together. Be sure that the gap between the platen
insulating panels does not exceed 3/8” (9 mm) or the bag will try to expand into the gap.
5. Install the pressure bags so the valves are on the same side or as close as possible. Always try to locate the
pressure bags so that the joint between bags does not coincide with the joint between platens. When platens
are all the same size on multiple arrangements, two half bags will be supplied so the bag and platen joint do
not coincide.

6. Install the bag plates on the pressure bags so that the joint between bag plates does not coincide with the
joint between bags.
7. The restraining bar will be in more than one section on arrangements over 96” (2.4 m). Join the restraining
bar sections using the union as shown.
8. When using more than one temperature controller, the main supply cable of each controller must be
connected to an adequate power supply.
Safety: Do not connect a main supply cable to the pump receptacle of any of the controllers because the
pump circuit does not have sufficient capacity for a platen set.
9. Connect multiple pressure bags and pumps to the distribution manifold supplied with multiple platen
arrangements, so they pressurize evenly.
4.7. Assembly of a Two Bar Vulcanizer
On vulcanizer arrangements with only two bar sets:
1. Install the restraining bars, upper and lower. With the gauge pin removed from one end, slide the bar
through each traverse bar and install the gauge pin. Both gauge pins should be approximately 3/4” (18 mm)
from the side of the outer traverse bars.
2. Install the supplied chains using the 5/8” diameter x 5 ½” long bolts, engaging all the threads on the nut.
3. The chains are usually only long enough to allow them to be stretched between the inside bar holes. The
chains should not be tight; some slack is appropriate (approx. 1 to 2 links should be loose).

SVP INSTRUCTION MANUAL Page 13
SHAW-ALMEX INDUSTRIES LIMITED 49909-010
Jun 2017
4. Please note that the nut on the bolt does NOT have to be tighten up against the bar side, as long as
the nut is fully engaged on the end of the bolt.
5. Please note that the 5/8” diameter bolts MUST be used to hold the chains in place.
*****Nothing should be substituted for these bolts.******
Only these bolts are sufficient to contain the chains in the event of a bolt failure.
Safety: The restraining bars, gauge pins, chains and bolt retaining pins are
safety components. When used together this feature will protect against
hazards that might result in the event of a bolt failure.
5. OPERATION
The procedure below describes the operation of the vulcanizer after the splice has been prepared and the
vulcanizer assembled. Separate instructions are supplied for the temperature and pressure controls.
5.1. Pressurizing
The vulcanizer can be pressurized with air up to 100 psi (690 kPa). For safety reasons, if the vulcanizer is
operated above 100 psi (690 kPa), use the hydraulic pressure pump. Always use an ALMEX pressure control to
pressurize the vulcanizer. Refer to the Air Control Manual or the Hydraulic Pressure Pump Manual if not
familiar with their operation.
The time to pressurize is generally much faster with air than water but in any case, the press will pressurize
within a few minutes. The larger the press, the longer it will take. With air, the pressure will begin to build up
soon after pressure is applied. With water, the hydraulic pump discharges at a certain flow rate and the bag must
fill before any pressure can build. It could take a few minutes for pressure to build but then it will reach
operating pressure quickly. Watch the pressure gauge carefully when pressurizing.
When the vulcanizer is pressurized, the traverse bars and platens will deflect a certain amount depending on the
pressure and the bar length. With the unique ALMEX flexible platen system and pressure bag, deflection in the
bars and platens does not affect the applied pressure.
Important: Be sure the vulcanizer is assembled correctly and that the restraining bars and gauge pins are
properly installed before pressurizing. If bars tend to roll or the frame appears unstable, release the pressure and
check frame alignment.
Safety: Do not lean against the vulcanizer when pressurizing. Since high stress levels are resident in the
frame and assembly members during operation, component failure can result in a sudden movement of
components. People must stay clear of the area when press is in operation.
Safety: Do not connect the vulcanizer to a continuous pressure supply. In the event of component failure,
it is important for the pressure to drop to a safe level.
Safety: The Pressure Relief valve of the Air Control is preset to blow off at slightly above the pressure
indicated on the air control. The Pressure Relief valve of the Hydraulic Pressure Pump is preset to blow off at 25
psi (170 kPa) above the operating pressure of the pump. Do not override this safety device or injury could
result.
Safety: Fingers must not be placed between platen surfaces when the vulcanizer is pressurized or injury
could result.

SVP INSTRUCTION MANUAL Page 14
SHAW-ALMEX INDUSTRIES LIMITED 49909-010
Jun 2017
1. Connect the pressure control hose to the pressure bag connection(s).
2. Pressurize the vulcanizer to operating pressure. Be sure air or fluid is entering the pressure bag(s) before
commencing to heat the platens. A simple check to ensure that each bag is pressurized is to wiggle the
pressure bolts. They will not move when there is pressure in the bag.
3. To de-pressurize the vulcanizer, slowly open the pressure release valve.
5.2. Heating the Vulcanizer
If not familiar with the operation of the temperature controller refer to the temperature controller manual.
Safety: Never leave the vulcanizer operating while unattended.
Important: There should not be water in the platens before heating or the platen heat will not be uniform.
Important: The element life will be significantly reduced if the vulcanizer is heated without being assembled
and pressurized.
1. Adjust the set point value of the temperature controller. It may be necessary to cycle power to the
temperature controller OFF and ON to reset the set point temperature. Check the temperature controller
manual.
2. Turn the switches on the temperature controller to the ON position. This may be labeled AUTO (Mark
VIII),or 1A (T4).
Safety: The platens will get hot.
3. Heat to set point temperature and then time the cure according to the belt manufacturer’s specification.
Monitor the platen temperature on the controller display as well as with the stem thermometers or
thermocouples inserted into the holes drilled into the platen edge.
4. When the cure is finished, turn the switches on the temperature controller to the OFF position.
5.3. Cooling the Vulcanizer
The platens can be allowed to cool naturally after they are switched off. Natural cooling can take several hours
so use this method only if cooling time is not important. The platens can also be cooled with compressed air that
is faster but will still take several hours.
The preferred method of cooling is to pump water through the platens. The cooling time depends on many
factors such as start and finish platen temperatures, cooling water temperature, water pressure, flow resistance
and platen area. Multiple platen arrangements take the longest to cool because of the greater area and the
restriction at the cooling ports. Generally the vulcanizer will cool to a safe handling temperature in five to ten
minutes per platen set.
The cooling hoses should be connected to platens during the press assembly so the cooling ports are easily
accessible and the platens are not hot.
The cooling ports on SVP platens are 1/8” NPT. Platens made in 1994 and earlier may have 1/4” NPT cooling
ports.
Important: The platens should be cooled while the vulcanizer is still under pressure and the platen heating must
be turned off.
Safety: The cooling water may discharge from the platen initially as steam creating a burning hazard.
Ensure the cooling water discharge is not directed at any person or injury could result.
1. When the cure time has been completed and the temperature controllers are switched off, turn on the water
supply to cool the upper and lower platens. When using an automatic temperature control, leave the
temperature controller connected to the platens so the temperature can be monitored.
2. When using the Hydraulic Pressure Pump for cooling, refer to pump manual.

SVP INSTRUCTION MANUAL Page 15
SHAW-ALMEX INDUSTRIES LIMITED 49909-010
Jun 2017
3. The cooling water can be turned off when the platens have cooled to an acceptable temperature. A typical
cool down temperature is 150F (65C) for a good splice result and safe handling of the belt without the
risk of a burn.
4. The water must be blown out with air before the platens are reheated.
Important: Water remaining in the cooling channels will reduce platen temperature uniformity, increase the
heat-up time and may cause the elements to overheat. Furthermore, if water remains in the platens and the
vulcanizer is stored at temperatures below freezing the platens may be severely damaged.
5.4. Depressurize
1. To de-pressurize the vulcanizer, slowly open the pressure release valve on the pressure control.
2. When the pressure has dropped to zero and the fluid has stopped flowing, the pressure supply can be
disconnected.
Safety: Do not attempt to disassemble the press until the pressure has been completely relieved or injury
could result.
6. MAINTENANCE
Safety: All maintenance must be done with the vulcanizer disconnected from the power supply and no
pressure in the bag.
There are no special tools required to maintain this equipment.
6.1. Routine Maintenance
The following items should be checked after every thirty cures.
1. Visually inspect the traverse bars, tie bolts and pins for signs of cracking or deformation. Some dry
lubricant can be applied to the bolt threads.
2. The threads on pressure bolts should be inspected using die penetrant after each 200 cycles.
3. Inspect the bolt retaining lugs at the ends of the bars to ensure that there are no cracks. Remove the bars
from service if there are cracks and contact Shaw-Almex.
4. Check the continuity of the platen heating elements. Refer to “Record of Purchase” for the resistance
(ohms) values. Use the figures from the “Ohms Reading Coils Connected” column. This is the resistance
between pins 1-2, 2-3 and 1-3 on the platen connector.
5. Check the continuity of the platen temperature
sensor. See 7.1 Platens Not Heating item 3
6. Inspect the platen pressure bag, hoses and
connectors for damage due to abrasion, cuts or any
type of damage that might cause a leak or
breakdown while under pressure.
7. Inspect all cables for cuts, abrasion and wear and all
“strain relief” fittings between cable and plugs for a
secure fit. If any cable, hose, fitting or pressure bag
shows signs of damage they should be repaired or
replaced.
8. Inspect the platen cooling for leaks and/or blockages that will affect their performance.
9. The platen insulation should be inspected for damage and for compression. Compression of the insulation
will cause the platen assembly screws to protrude above the insulation. If the screws cannot be tightened,
the insulation should be replaced.
Tip: Assembly bolt threads on Almex vulcanizers are coated with an anti seize compound to facilitate removal
and replacement of components in service. This compound will be worn off when assembly bolts are removed

and therefore the threads should be re-coated before re-assembly. The surfaces should be free from dirt, oil,
grease, moisture and rust and the compound applied evenly to bolt threads.
6.2. Removing and Replacing the Platen Receptacle Insert
The contact pins in the platen insert should be inspected
occasionally for damage from wear, corrosion, or arcing.
If the pins are damaged, the insert must be replaced. The
cover should always be used when transporting or storing
the platens to keep the receptacle clean.
Important: The platen insert is made from a special
material capable of resisting the high platen temperature.
Contact SHAW ALMEX for the proper replacement part.
1. Remove the electrical connector housing from the
platen edge by loosening the four screws and
carefully pull the gasket, housing and insert away
from the platen.
2. Remove the insert from the housing by loosening the
four screws and carefully pull the wires through the
gasket.
3. Disconnect the RTD probe, element and ground
wires from the insert.
4. Attach all wires to the new insert. Connect the
yellow RTD probe lead to terminal 4 and the two
white wires to terminals 5 and 6.
5. Install the insert in the housing.
6. Hold the wires and slide the gasket along the wires
until is it against the housing.
7. Rotate the housing several times to wind the wires
into a loose bundle and then carefully bend the wires
into the adapter.
8. Make sure there are no wires pinched and fasten the housing to the adapter.
6.3. Replacing the Temperature Sensor (RTD Probe)
1. Remove the electrical connector insert from the
platen. See 6.2 Removing and Replacing the Platen
Receptacle Insert.
2. Disconnect the RTD probe wires from the insert and
pull through the gasket. The element wires can
remain connected.
3. Remove the RTD probe from the platen. See Figure
16 RTD Probe. If the probe does not come easily,
make a ¼” (6mm) hook on the end of heavy wire
and slide it down the channel to the bottom of the
probe (approximately 8” or 200 mm) and pull. If it
is not possible to pull out the probe it must be
drilled out with a ¼” (6 mm) diameter, 9 inch (230
mm) long drill.
4. Trim the wires on the new probe to the same length
as the old probe.
5. Insert the RTD wires through the appropriate holes in the gasket so the yellow wire aligns with terminal 4
and the two white wires with terminals 5 and 6. The probe wires should have small metal sleeves crimped to
