APPENDIX
9. 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;
passing the kneaded plastic to an intermediate buffer
reservoir;
intermediately storing the kneaded plastic at a
controlled temperature in said intermediate buffer reservoir;
supplying the kneaded plastic, after said intermediate
storage, to injection molding equipment;
molding said kneaded plastic into a product in said
injection molding equipment, said molding step being affected
intermittently; and
affecting quasi-continuous flow of plastic material from
said kneading step, said passing step, said intermediate
storing step, and said supplying step with said intermediate
storing step compensating for the difference in the plastic
material flowing from step to step.
