Grafotec gets seal of approval for new coating device

Manufacturer of separator application systems Grafotec Spray Systems has successfully completed testing a liquid application system with a German customer.

Grafotec’s new roller application device can coat float glass with anti-corrosion liquid using a single, continuous roller.

The application quantity is regulated via a shutter control and automatically adapts to different web speeds in order to keep the desired application quantity constant.

The roller generates a spray mist without any spray nozzles and the glass edge tracking, which works independently on both edges, automatically limits the liquid application to the glass ribbon. Glass edge tracking allows the spray to reach the glass ribbon without getting on the conveyor and the floor.

Using a programmable logic controller and a 20 ins colour touch screen, an operator can control and monitor the entire system as well as preparation of the anti-corrosion liquid.

From a barrel or canister, the concentrate is mixed with the process water as required and the concentration of the mixture is kept constant.

The new system was commissioned in April 2021 and Grafotec’s service and construction team anticipates completion of a further system.
