摘要： The invention relates to a device for determining the operational state of an extruder that is used for the production of a plastic profile. At least one measuring device for determining the quality of the melt is provided in an adapter part between an extrusion cylinder (3) and an extrusion nozzle (5). An especially exact determination of the extruder state is possible if the measuring device comprises a tube through which melt is continuously drawn off from the adapter part during the measurement and on which at least one pressure absorber is disposed.

摘要： The invention relates to a method for producing plastic profiles comprised of at least one hard profile strand (2), for example, consisting of hard PVC, and of at least one soft profile strand (1), for example, consisting of soft PVC, whereby both profile strands (1, 2) are simultaneously produced by separate extrusion nozzles (20, 17a) and are cooled in a cooling device (16, 18). A secure joining can be effected using simple means by leading the soft profile strand (1) directly out of the extruder (17) and into a cooling bath (16, 18), inside of which it is completely cooled, and the hard profile strand (2) and the soft profile strand (1) are subsequently joined under pressure.
