Zusammenfassung:	A tire tread production line and a method for manufacturing a tire tread is disclosed. The production line comprises: a coextruder (12) for coextruding at least two rubber compositions, the coextruder (12) comprising at least two feeding inlets (22) for receiving the at least two rubber compositions, the coextruder (12) further comprising one or at least two screws (24) for driving the received at least two rubber compositions, an extrusion die (26) for forming a multi-layer tire tread extrudate (128), the one or the at least two screws (24) being configured to drive the at least two rubber compositions in the extrusion die (26); a THz sensor (14), the THz sensor being configured to irradiate the multi-layer tire tread extrudate (28) with THz electromagnetic radiation, and receiving a response of the multi-layer tire tread extrudate (28) to the THz electromagnetic radiation; and a controller (18) operatively connected to the coextruder (12) and to the THz sensor (14), the controller (18) being configured to operate the coextruder (12) based on the response of the multi-layer tire tread extrudate (28) to the THz electromagnetic radiation.
