immediately or directly before the subsequent treatment because that is where
straightness of the strip is needed.
For the above reasons we are not convinced of reversible error in the
rejection over Mücke.
Rejection over Reesor
Reesor discloses “an automatic control system for detecting and controlling
ripples or irregularities from the surface of a sheet or strip as it passes through strip
leveling devices, such as roller levelers in a continuous sheet or strip processing
line” (col. 1, lines 9-13). An example of a strip processing line is a galvanizing
line (col. 2, lines 18-19). The strip is flattened by passing it through a leveler (12)
consisting of two decks of parallel rolls, one on each side of the strip, in staggered
relationship (col. 3, lines 68-69; col. 4, lines 53-57). Any ripples in the flattened
strip are detected by a circuit connected to a follower wheel (13) that rides up and
down over the ripples (col. 3, line 72 – col. 4, line 14). When a ripple voltage
output rises to a value corresponding to a preselected minimum ripple, a level
adjustment motor (22) starts running and adjusts the leveler (12) to eliminate the
ripples (col. 4, lines 30-35).
The appellants argue that Reesor does not disclose adjustment of a
correcting roller in response to an error signal in conjunction with a strip
