Abstract
The invention relates to a method for producing plastic profiles comprised of at least one hard profile strand (), for example, consisting of hard PVC, and of at least one soft profile strand (), for example, consisting of soft PVC, whereby both profile strands () are simultaneously produced by separate extrusion nozzles () and are cooled in a cooling device (). A secure joining can be effected using simple means by leading the soft profile strand () directly out or the extruder () and into a cooling bath (), inside of which it is completely cooled, and the hard profile strand () and the soft profile strand () are subsequently joined under pressure.
