<p>A system and method for dispensing liquid coating patterns of varying width. The system uses a film coater (20), a liquid supply (22) coupled in fluid communication with the film coater (20) and configured to supply liquid to the film coater (20) under pressure, and a liquid pressure regulator (24) operatively connected to the coater (20). The liquid pressure regulator (24) selectively adjusts the pressure of the liquid supplied to the film coater (20) and is operated by pressurized air. A selector valve (26) is coupled to the liquid pressure regulator (24). First and second air pressure regulators (30,32) are coupled to the selector valve (26) and can selectively deliver air at first and second pressures to the selector valve (26). The selector valve (26) is moved between first and second positions for selectively delivering air under either the first pressure or the second pressure to the liquid pressure regulator (24) to thereby cause the liquid to be delivered to the film coater (26) at different pressures to change the width of the dispensed pattern.</p> |
