FEATURES

The Addex Manual Gauge Control Air Ring is based uponour Dual Lip Air Ring that has been the standard for theblown film industry worldwide.

The MGC permits selective adjustment to correct film gaugedeviation caused by extruder, die, or ambient anomalies byas much as 25% (several customers have achieved a 50%reduction).

Depending on die size, the MGC is equipped with anywherefrom 100 to 304 individually adjustable control bolts in10mm (3/8”) wide air vanes, providing high resolution, yetrequiring only average operator skills.

Because it is manually operated, its price is only a fractionof an automatic system.

Making gauge corrections with the MGC can best be com-pared to adjusting die bolts to make up for uneven filmthickness distribution.

A spot is marked on the film bubble, indicating its orienta-tion, the gauge of the film sample with the marking ismeasured off line and plotted, and the relative adjustingbolts on the MGC are turned in or out to make corrections.The magnitude of correction per bolt turn can also bedetermined by before and after film measurements.Although the MGC lends itself to use with stationary aswell as oscillating/rotating dies, the latter can control onlyabout half the gauge deviations.

In addition to the MGC, Addex also manufactures a fullyautomatic External Gauge Control system (EGC), and anautomatic Internal Gauge Control system (IGC).
