Application No. 08/190,566
This is a decision on an appeal from the examiner’s final
rejection of claims 4 through 14 which are all of the claims
pending in the application.
Claim 4 is representative of the subject matter on appeal
and reads as follows:
4. A method for compression molding of a resin article
comprising the steps of:
providing opposing male and female mold portions, the
mold portions being movable between open and closed states;
introducing a resin material in a flowable state between
the mold portions while the mold portions are in the open
state;
moving the mold portions toward one another from the open
state to the closed state;
spreading the resin material between the male mold
portion and the female mold portion as the mold portions are
moved to the closed state;
forcing air from a cavity between the male mold portion
and female mold portions as the mold portions are moved to the
closed state, the air being forced through a space between the
male and female mold portions;
forming an annular mating gap between the male and female
mold portions in the closed state, the annular mating gap
being formed by a flange on the female mold portion which
overhangs sidewalls of said male mold portion by a distance L
in a mold closing direction forming a mating edge therewith
when the molds are closed;
providing the distance L to satisfy the equation
(t - t + 10) mm > L > (t - t ) mm,1 0 1 0
