Absolute Precision
While the Haul-off oscillates with absolute angular precision around the extrusion axis, the solid Gear System kinematics transform the Rotating Platform torque into an alternating rotation of a referring planes series.
Combined Action
The almost no-friction offered by the combined action of air cushions and low roughness coatings, guarantees an undisturbed redistribution of localized thickening along the entire bubble circumference.
A homogeneous reel inertia for dynamic balance purposes is then guaranteed.
