Abstract
The invention relates to a device for the extrusion of plastic profiles with an extruder for the melting and delivery of a plastic material and with an extrusion die for defining the profile geometry, wherein a profile slot corresponding to the profile to be extruded and being defined by an outer periphery and by at least one arbor is provided in the extrusion die. The profile tuning is made easier by having a means for operational change of the profile slot's thickness provided in at least one predetermined area between the arbor and the outer periphery as well as a means for cooling selected areas of the extruded profile provided at the exit of the die.
