Claim:
1. An extrusion device for the extrusion of a plastic profile with at least one single walled profile section, in particular a nozzle plate, the extrusion device comprising: at least one plastic melt flow channel for the at least one single walled profile section; one or more other plastic melt flow channels for one or more other profile sections that exclude the at least one single walled profile section; and at least one local temperature control device positioned proximate to at least one wall region of the at least one plastic melt flow channel for the at least one single walled profile section to temperature control in a targeted manner the at least one wall region of the at least one plastic melt flow channel for the at least one single walled profile section for setting the flow speed of the plastic melt through the at least one plastic melt flow channel for the at least one single walled profile, wherein the extrusion device is devoid of local temperature control devices positioned proximate to the one or more other plastic melt flow channels.
