IE B021TREATMENT REPORT ON TR-11 TYRE BUILDING MACHINES · ROSAVA JSC, 2005
TR-11 building machines: screw pair treatment cut power consumption
Drive idle current dropped, power consumption per cycle decreased, the drive ran freer. 42.6–59.7 % — power consumed per machine work cycle, 1.566–3.098 → 0.853–1.649 kW; 26.5–37.0 % — no-load current with the plate travelling forward, 4.8–7.3 → 3.5–4.6 A (2005).
