<p>A pour-in funnel (1) generates a continuous feed flow in a pipeline (3) with several feeder cylinders (Z1-Z3) in connection with a rotary slide valve (2) that rotates around an axle and can operate between the cylinders fitted with equal clearance around the axle so as to open the cylinders into the funnel, to close them against it and to link the cylinders to the pipeline.</p> |
