63-64). There appears to be no dispute that Yankaitis discloses
a wire cutting apparatus comprising a cutter holder carried by a
support, the cutter holder having a wire cutter, an electric
motor 40 carried by the support having an output driving the
cutter holder, and a proximity sensor 52 arranged downstream of
the cutting station arranged in sensory communication with the
wire cutter adapted to produce a signal indicating presence of
wire in proximity to the end of a predetermined wire path.
The examiner concedes that Yankaitis does not have an
additional proximity sensor arranged in sensory communication
with the wire cutter adapted to produce a signal indicating
location of the wire cutter relative to the wire path, or a
controller responsive to both proximity sensors to control the
electrical motor by selectively generating a first electrical
output to drive the motor and work the wire cutter into the
predetermined wire path and a second electrical output to
decelerate the motor and maintain the wire cutter adjacent to the
predetermined wire path. The examiner turns to Green for a
teaching of these features.
Green pertains to a differential integral controller for
controlling a rotary knife for cutting sheet material. According
to Green (column 1, lines 47-66), the invention thereof
