An extruder die head for producing multilayered tubes made of thermoplastic material includes a central annular channel, which is provided with an annular outlet. Annular slits in the walls of the channel are used to feed a polymer melt into the annular channel. The annular slits constitute the smaller diameter openings of tapered channels, formed in the internal and external surfaces of pairs of stacked, conical rings. To reduce the axial length of the extruder die head, the annular slits, through which the polymer melt passes, also empty into the inside wall of the central annular channel. The shortened flow path of the melt reduces melt degradation problems associated with prolonged heating, and reduces the stress at melt interfaces.
