Appeal No. 1997-0668
Application No. 08/232,854
This is a decision on an appeal from the final rejection
of claims 9, 11 and 18 through 25 which are all of the claims
pending in the application.
The subject matter on appeal relates to a method for
molding a product from recycled plastic which has been
presorted comprising the steps of kneading the recycled
presorted plastic substantially continuously so that it is
simultaneously comminuted, mixed, heated, melted and
homogenized and then passing the kneaded plastic to an
intermediate buffer reservoir for intermediate storage therein
and thereafter supplying the kneaded plastic to an injection
molding equipment and effecting quasi-continuous flow of
plastic material from said kneading step, said passing step,
said storage step and said supplying step. This appealed
subject matter is adequately illustrated by independent claim
9, a copy of which taken from the appellant’s Brief is
appended to this decision.
The references relied upon by the examiner as evidence of
obviousness are:
