When a freshly extruded tire carcass rolls out of the curing oven and reaches the bead‑mounting station, the pneumatic cylinder fires to clamp the bead‑wire and drive the press ram into position. Its linear motion synchronises the opening of the feed guide, the gripping of the carcass, and the precise lowering of the bead‑press tooling, allowing the wire to be pressed onto the rubber without slippage. The cylinder’s quick stroke and reliable return keep the timing of each cycle tight, which is essential for maintaining the high throughput demanded by modern tire plants. Because the same actuator can be re‑programmed for different press sizes, it also supports change‑over when the line switches between passenger‑car and light‑truck tire formats. In the adjacent rubber‑mixing area, the same type of cylinder is used to actuate the discharge gate of a mixing kettle, ensuring that the hot compound is emptied cleanly before the next batch starts. The cylinder’s fast retract lets the next carcass be positioned without delay, preserving the line’s short cycle time.
