More Information
Summary:Apparatus and method for spray coating of a horizontally moving web uses a spray-down unit that sprays downwardly onto the web and a spray-up unit that sprays upwardly onto the web. Each unit has adjustable cut-offs that control the length of the spray pattern by intercepting end portions of the spray pattern. The cut-offs of each unit can be adjusted to block a spray emission opening so as to prevent the entrance of contaminants when the unit is not in operation. Fluid intercepted by the cut-offs is returned for re-use. Both units are supported on a frame, and the spray-down unit can be moved away from the spray-up unit.
