When a tire‑building line has to change quickly between different carcass sizes, the pneumatic actuation system needs a steady supply of dense‑phase airflow to keep the positioning cylinders responsive. The Börger dense‑phase pneumatic pump delivers that high‑pressure air directly to the network of cylinders that lift, stretch and place the fabric and steel plies on the drum, as well as to the air‑inflation system that pressurises the green tire before curing. Its ability to provide a constant flow at relatively low velocities prevents pulsations that could disturb the delicate alignment of the layers, allowing cycle times to stay within the line’s tight schedule. Because the pump is mounted close to the drum and integrated with the plant’s compressed‑air infrastructure, it can be serviced or replaced without stopping the entire line, minimizing downtime. In addition to the primary tire‑building function, the same pump is often used in nearby material‑handling stations to convey fine rubber granules or dust‑free powders, where a dense‑phase gas stream moves the particles safely and efficiently. This dual role makes the pump a practical choice for modern tire factories that demand both precise tire assembly and reliable auxiliary material transport.
