Abstract
A discharge nozzle connected to the outlet of an extruder is built wedge-shaped in vertical longitudinal section and comprises a lower housing part and an upper housing part. The upper housing part is adapted to be swung open by being pivoted around a pivot axis, thus causing the nozzle to open. This opening of the nozzle occurs under the influence of a control and actuating member, as soon as a predetermined value of twisting moment, pressure or temperature is exceeded. The nozzle discharge opening has shutting locking bolts associated with it, adapted to shut off the discharge channels of the discharge opening of the nozzle. The discharge nozzle may be used to advantage for the continuous processing of electrode material.
