ABSTRACT:
The present invention concerns an integrated die extrusion vessel with controlled circular distribution of the extruded material. In particular its object is an extrusion vessel or head which can be fitted by its base to the exit of an extruder and which comprises at its top a die including radial distributing means equidistant from each other on the same circumference and designed to calibrate and control the flow rate of the strands of extruded material coming from the extruder and passing through crown arranged orifices and passing through the base plate of the vessel, and further designed to balance match these material strands to the geometry of the shaped section before they enter the die.
