Abstract
An improved system for applying a coating to a sheet is disclosed. The system allows precise control of the actuation of the valves and movement of the nozzle to create a plurality of coating profiles. The system includes a controller, which is used to actuate the valves to begin and terminate the flow of material onto the sheet through a nozzle. In addition, the controller may move the nozzle from its operative position to an inoperative position away from the sheet. In some embodiments, a fluid displacement mechanism is used. The controller is also able to coat the opposite side of the sheet. Registration of the coating can be programmed to be in exact alignment, or advanced or delayed by a specific amount.
