Working Principle:

1. Joint Preparation: The two belt ends to be joined are skived (step-cut) and buffed, then coated with a special cement.

2. Clamping & Positioning: The prepared belt ends are aligned and placed between the press's upper and lower heated platens. The frame and hydraulic system clamp them together under initial pressure.

3. Heating & Pressurizing: The machine is activated. The electric heating platens raise the temperature to a preset vulcanizing level (typically 140°C - 160°C). Simultaneously, the hydraulic system applies uniform and constant pressure (e.g., 10-20 MPa), forcing the splice materials to flow and bond intimately under heat and pressure.

4. Curing: The temperature and pressure are maintained for a predetermined time to ensure complete vulcanization.

5. Cooling & Release: After curing, heating stops. The joint is allowed to cool under pressure or naturally to a safe handling temperature. Pressure is then released, and the belt is removed.
