Alpha Marathon Technologies: Dual-Lip Ring Adjusts Each Air Flow Separately

A new approach to tuning a dual-lip air ring is said to be the first to tune the two lip gaps independently. Dual-lip air rings are usually tuned by moving a single flange that adjusts the ratio of air between the two lip openings. The new Reciprocating Air Technology for the Millennium Air Ring from Alpha Marathon Technologies Inc., has knobs above and below the air ring, which independently adjust two control mechanisms. Alpha Marathon says this gives greater control of air velocity for better gauge control of very thin (0.4- to 3-mil) film. It reportedly also can help boost output by 20-30%.
