Abstract
An extrusion die for extruding hollow profiles is suggested having a die head (), which is connected to a runner part () and forms extrusion channels () for shaping a profiled strand (), and having a runner chamber (), which is provided between the die head () and the runner part () and runs transversely to the extrusion channels (), which is connected around its circumference () to an annular channel () for impingement with plastic melt and from which the extrusion channels () of the die head () originate. In order to provide advantageous construction conditions, it is suggested that the runner part () have an inner channel () discharging into the runner chamber () inside the annular channel () for additional impingement of the runner chamber () with plastic melt.
