摘要:
The invention relates to an extruder head for extruding cord reinforced extrudate, wherein the extruder head comprises a die and a cord guide, wherein the extruder head further comprises a first flow channel that extends along a first flow path through the extruder head at and debouches into the die from a first side of a cord plane and a second flow channel that extends along asecond flow path through the extruder head at and debouches into the die from a second side of the cord plane, wherein the first flow path and the second flow path each comprise a supply section and a coat-hanger section, wherein the first flow path and the second flow path, in their respective coat- hanger sections, extend within a first range of eighty-five to ninety-five degrees with respect to the cord plane along at least seventy percent of the coat-hanger sections.
