  • Patent number: 10478853
    Abstract: Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and 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 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 be actuated to move the web back into contact with the coater to start the application of slurry to the web, 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.
