Appeal No. 96-3441
Application 08/137,868
b) claims 3 and 4 as being unpatentable over Field in view
of Tajima, and further in view of Stubbins.
Field discloses a rolling mill arrangement which includes a
mill stand 10 and a roll assembly platform 18. The platform is
located adjacent the stand and is adapted to carry two roll
assemblies for interchangeable mounting on the stand. The roll
assemblies contain different roll configurations which can be
pre-adjusted for spacing and attitude to produce products having
different shapes. One of the roll assemblies is a universal roll
assembly 44U and the other is a “two-hi” assembly 44T. The stand
includes drive and operator side roll mounts, each in the form of
a pair of standards 20 connected at their tops by junction 22 and
at their bottoms by base member 24. These side roll mounts are
joined to one another at their tops by member 56 and at their
bottoms by base 58 so as to form a unitary rigid structure. This
unitary rigid structure is transversely movable between its
operative position and a position adjoining the platform to allow
the roll assemblies to be transferred between the two. In this
regard, both the mill stand and the platform contain transversely
extending rails along which the roll assemblies ride. The
platform is longitudinally movable relative to the stand to
suitably align the rails.
