OPINION
We affirm the rejections under 35 U.S.C. § 103, reverse the rejection under
35 U.S.C. § 112, and remand the application to the examiner.
Rejection over Mücke
Mücke straightens metal strip to eliminate departures from flatness that need
to be eliminated for subsequent treatment of the strip and for use of the finished
strip (col. 1, lines 5-12 and 23-35). “Such departures from flatness can take the
form of curvature of the strip in the longitudinal direction, transverse curvature and
transverse, central and edge waves or the formation of a camber as a result of
differences in the width of the strip” (col. 1, lines 14-18). The strip is straightened
by being plastically deformed as it passes through two straightening gaps, each gap
being between a straightening roll (18 and 19) (one straightening roll being on each
side of the strip) and a pair of backing rolls (14, 15 and 16, 17) (each pair of
backing rolls being on the side of the strip opposite the respective straightening
roll) (col. 4, lines 1-24; fig. 3). “On the exit side three sensors 29, 30 are arranged
above the strip 5 by means of which any curvature of the strip remaining after the
straightening can be determined and compared with an intended value. Using an
algorithm, it is thus possible to control the straightening rolls” (col. 4, lines 31-35).
