Improvements in or relating to die heads for extruding plastics materials.

摘要

The die head (11) includes an inlet (19) for receiving a continuous supply of plastics material to be extruded, and a duct distribution system (21 - 43) for directing said material from said inlet to an extrusion outlet or outlets of the head; and is characterised in that the duct distribution system forms a "family tree" system arranged to direct said plastics material supplied to said inlet to spaced apart locations adjacent said outlet or outlets via paths of substantially equal lengths.
