Abstract

An extrusion die (10) for producing an extrudate of thermoplastic material. The extrusion die includes a slotted die outlet (12) through which a melt stream of the thermoplastic material is extruded, the slotted die outlet comprising a first die lip (46) and a second die lip (48), and a plurality of cantilevered adjustment members (60,66) extending normally from the first die lip, the plurality of cantilevered adjustment members each having an externally actuatable means. A process for making an extrudate of thermoplastic material is also provided.
