metering element and the moving material web and/or by varying
the pumping rate of the coating medium from the applicator device
to the moving material web (col. 5, lines 1-5; col. 8, lines 59-
65). McAleavey states that “[t]he present invention, generally
speaking, provides a system and method for monitoring and
controlling the thickness of laminates” (col. 2, lines 2-4). The
only disclosed application of the system and method, however, is
for applying cathode and electrolyte layers to a metal substrate
in the formation of a battery (col. 3, lines 23-61).
DE ‘183 discloses a method for regulating the cross-
sectional coating weight of a fluid or pasty medium which is
applied by an applicator to a traveling paper or cardboard web
and then is spread to a final coating thickness by a doctor
element (pages 1-2). The applicator includes a dosing slot (4)
having lips which are adjustable so as to vary the distance
between them and, thereby, to vary the flow of liquid or pasty
medium, the adjustment advantageously being accomplished by a
control circuit based upon the measured cross-sectional coating
weight of the fluid or pasty medium. See id. Long wave and
short wave corrections of the coating weight advantageously are
obtained by, respectively, the dosing slot and the doctor
