Abstract (en)
[origin: EP0320575A2] In order to achieve improved strand quality, the flow conduit for the melt is kept free of deposits at the throttling edges of the slide gate nozzle by an opening stroke of the slide plate, performed in coordination with the automatic control of the setpoint filling level, out of the throttling position into a new throttling position. <IMAGE>
