Appeal No. 2002-2230
Application 09/295,547
[t]he generator 69 produces motion curves with regard
to the following functions "(t) for the run or course
of travel for the hook member; d"/dt for the speed of
the hook member; and d2"/dt2 for the rate of
acceleration for the hook member. The values of these
curves, either from FIGS. 3 or 4, are then sent to a
pulse convertor 71, which converts them into the
information which is acceptable by the drive motor 47
[column 5, lines 27 through 35].
In Genoud’s method of determining when to trigger a hook for
folding a back flap of a moving carton such that the hook strikes
the back flap at a strike point for folding, each of the motion
curves shown in Figures 3 and 4, which display velocity,
acceleration and phase positioning (or course) data representing
a pattern of rotation of a hook member, constitutes a cam profile
as recited in claim 1. Genoud’s production of a motion curve by
the generator 69 would have suggested the recited step of
receiving a cam profile representing a pattern of rotation of the
hook from a start position to an ending position in order to
strike the back flap at the strike point and to fold the back
flap. Genoud’s conversion by the converter 71 of the motion
curve into information acceptable by the drive motor 47 would
have suggested the recited step of automatically generating from
the cam profile a cam cycle representing electronic control
signals for velocity, acceleration and phase positioning of a
motor controlling the hook in order to execute the cam profile.
