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.
