Abstract

A tool for extruding a tubular thermoplastic melt, comprises a ring shaped outlet nozzle (5) and a melt channel that runs concentrically to the central axis of the tool. A spiral distribution unit is located in the wall of the unit, and the spiral is located in the inner wall (60) and the outer wall (61) of the melt channel. The spiral has a semi-circular cross section, and the spirals in the inner and outer walls are displaced with respect to one another in the outlet direction. The depth of the spiral reduces from the inlet in the outlet nozzle direction.
