Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and for coating a web. The device creates a web hold down force via a negative pressure slot at its exit side, which draws the web down against the surface on the entry side. The device can be actuated to move the web relative to a slot die coater off the die lips and stop the application of slurry to the web, thereby creating uncoated regions on the web surface. The device can then be actuated to move the web back into contact with the coater to start the application of slurry to the web, thereby creating coated regions on the web surface. Web lifting can be accomplished by rotating the device in first and second directions to lift the web off of the slot die coater and return the web back into contact with the coater.

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.
