Abstract:
1. A device for generating a hollow plastic profile, in particular a plastic tube, comprising: an extrusion die having an extrusion axle and a melt channel encompassing the extrusion axle, said extrusion die including a spiral distributor; an extruder feeding the melt channel with plastic melt in a direction centrally upon the extrusion axle for extruding the plastic melt in an extrusion direction and thereby forming a hollow profile; and a suction device for drawing air though an interior of the profile in a suctioning direction in opposition to the extrusion direction, said suction device having a central suction tube which is arranged within the melt channel, and partial flow suction channels which are connected in the suctioning direction to the central suction tube and sized to lead out from an interior of the extrusion die, said partial flow suction channels extending in supply bores provided in the spiral distributor of the extrusion die.
