The Examiner’s Rejections
Claims 1, 2, 4, 6-8, 10 and 12 stand rejected under 35
U.S.C. § 103 as being unpatentable over Sieberth or Murray
‘088 or Murray ‘927 in view of Kuhnel. The examiner concedes
that the primary references are silent as to controlling the
speed of the separate backing rollers for the coating
applicator and doctor units. However, the examiner considers
that it would have been obvious to provide the separate
backing rollers in the primary references with independent
drive means in order to achieve proper web tension in view of
the teachings of Kuhnel.
