Appeal No. 97-1365
Application 08/295,
Opinion
We are in agreement with the examiner that Imai discloses a roll type stock feed
apparatus including rollers 13 and 11. We further agree that member 18 of Imai can be
construed as a roll carrier. Spring 20 of Imai comprises the pressure applying means
which yieldably urges the roll carrier 18 of Imai into stock feed position. However, Imai,
as admitted by the examiner, does not disclose an elongated ram position sensor
member slidably mounted on the stationary frame structure for lengthwise reciprocation
along an upright path and having an upwardly facing abutment. Nordlof shows member
101b which senses the position of the ram via the actuator member 102a and is
slidably mounted for reciprocation along an upright path. Moreover, the member 101b
also has an abutment upwardly facing as claimed in appellant’s claims. However, in
Nordlof, the roll carrier means is reciprocated by means of pneumatic piston 71 and no
interengaging cam means is provided for moving the roll carrier means in response to
movement of the ram position sensor member.
In our view, if the suggestion or teaching of Nordlof were combined with the
teachings of Imai, the teaching of Nordlof is to remove the mechanical camming of Imai
entirely and to go to a pneumatically controlled servo system. This servo system would
be used to move the roll carrier means 18 of Imai just as Nordlof teaches moving 36,
his roller carrier means in his patent. In other words, while the combined teachings of
the Nordlof and Imai disclosures do result in the elongated ram position sensor member
