Extruder system and method for extruding cord-reinforced tire components

A method for extruding cord reinforced extrudate, the method comprising:

• providing an extruder system for extruding the cord reinforced extrudate, the extruder system including
• an extruder head with one or more flow channels for receiving an extrusion material from an extruder,
• a die for receiving said extrusion material from the one or more flow channels, and
• a cord guide for guiding cords side-by-side in a cord plane into the die,
• wherein the extruder system further comprises a holder for holding the die with respect to the cord guide,
• wherein the extruder head is provided with an insertion slot that extends in an insertion direction through the extruder head, wherein the insertion direction extends parallel to the cord plane from an insertion opening of the extruder head to a flow area downstream of said insertion opening,
• wherein the one or more flow channels debouch into the insertion slot at said flow area,
• wherein the die and the cord guide are insertable in the insertion slot in the insertion direction from a position completely outside of the insertion slot through the insertion opening into a die position downstream of the flow area and a cord guide position upstream of the flow area, respectively, with respect to the insertion direction, and
• wherein the die is arranged to be connected to the cord guide by the holder prior to insertion such that the die and the cord guide are simultaneously insertable in the insertion direction into the insertion slot;
• wherein the method further comprises the steps of connecting the die and the cord guide and inserting the die and the cord guide simultaneously from the position completely outside of the insertion slot in the insertion direction in the insertion slot into the die position and the cord guide position, respectively.
