Abstract
The invention relates to a mixing device for a twin-screw extruder, in particular a twin-screw extruder rotating in the opposite direction, comprising a first screw and a second screw, for mixing a melt flow in a screw antechamber, wherein the first screw has an extension in the form of a mixing screw tip connected to the first screw in a fixed manner, and a first melt channel, into which the first screw feeds, is arranged in a flow-connected manner via an elongated slot with a second melt channel, into which the second screw feeds.
