Industrial Air Cooled PVC PU Conveyor Belt Vulcanizing Press Joint Splice Machine

Introduction to the Splice Press

The splice press is an all-in-one solution for splicing thermoplastic conveyor belts (e.g. PVC polyurethane).

No external control box, air pump, or water cooling tank are required.

The presses are provided with electric heating and built in air cooling. The splice process runs fully automated.

Machine specification of Industrial Air Cooled PVC PU Conveyor Belt Vulcanizing Press Joint Splice Machine

• Splice pressure is applied by an internal compressor, max. 2 bar (28 psi)

• Heats up to a splice temperature of max. 200°C (392°F)

• Keeps it at the splice temperature (adjustable dwell time)

• Cools down to the cooling temperature (safe temperature to take the belt out)

• For thicker belts a preheat temperature and preheat dwell time can be applied

• The bottom heating can be set lower or higher than the top heating

• The splice surface is 130 mm ; the heated zone is 110 mm.

If the belt is relatively thick a problem might occur where the outside of the belt is at the splicing temperature too long, waiting for the inside to reach the required temperature. Molten material might flow away or discolor and fabrics might shrink. To avoid this problem from happening, the preheat option can be used. This option heats the belt up (outside and inside) to a temperature just below the melting temperature. After the preheat stage, the inside splice temperature can be reached much quicker, minimizing the risk for unwanted flow of material, discoloring or fabric shrinkage.

The reading of the display relates to the top temperature of the press. If more or less heat is required at the bottom of the belt, the “bottom heat factor” can be used. Please note that this factor relates to a plus or minus amount of heat (%), not to a specific temperature.

Presses are available in 5 different sizes:

• 300 mm effective (12")

• 600 mm effective (24")

• 900 mm effective (36")

• 1200 mm effective (48")

• 1500 mm effective (60")

Presses function on different voltages
