Abstract

Provided is an extruder and a method for extruding cord reinforced tire components, wherein the extruder has an extruder head with a die and a cord guide. The die is provided with a cross sectional profile that defines a first cross section of the extrusion material in the die, wherein the cross sectional profile has a profile height. The cord guide is arranged for guiding the cords into the die at a cord entry height. The extruder head is provided with first heating elements. The extruder has a control unit that is operationally connected to the first heating elements for generating an adjustable height temperature gradient in the extrusion material across the profile height to control swelling of the extrusion material relative to the cord entry height from the first cross section to a second cross section after the extrusion material leaves the die.
