Appeal No. 97-1365
Application 08/295,
DECISION ON APPEAL
This is an appeal from the examiner’s refusal to allow claims 1 through 6 as
amended after final rejection. Claim 7, the other claim remaining in the application, has
been indicated by the examiner as allowed.
The claimed invention is directed to a roll type stock feed apparatus for
intermittently advancing a strip stock into a power press having a ram which vertically
reciprocates through a ram cycle. The feed apparatus is arranged to release feed
pressure on the stock during a portion of each press cycle so that pilot pins can enter
pilot holes in the strip stock to position the stock properly before the pressing operation.
Appellant accomplishes this feed pressure release by provision of a ram position
sensor means 71 which is actuated by an actuator affixed to the ram. As the ram
position sensor member is reciprocated downwardly in response to the ram’s cam
downward movement surface 83 on the sensor position member cams bell crank lever
85 which raises the roll carrier arm 25 thereby raising feed roller 23 with respect to the
stock.
