Zusammenfassung:	In a cost-effective and qualitatively better method for producing spacers for a winding unit of an electrical high-voltage device, at least two starting components are mixed together in a mixing chamber under vacuum to form a component mixture. The component mixture is transferred to an extrusion housing, likewise under vacuum, of an extruder in which a transport device is arranged and which is equipped with a mouthpiece delimiting an outlet opening. The extrudate exiting from the mouthpiece is cured by the addition of heat in a vacuum in order to obtain the spacers.
