Abstract

A plastic filament is continuously heated and fed into an apparatus generating helical articles having a rotary drum supporting an injection nozzle, such that it should be urged to be opposite a threaded mandrel likewise supported by a drum and be linked by a common rotating movement with said mandrel. The filament coming out of the nozzle penetrates slidingly into the thread grooves of the mandrel in a spiral configuration, the mandrel being radially and coaxially enclosed by a cooled sleeve. The filament will then be solidified along the thread groove of the mandrel, so as to form a plastic helical article continuously coming out by the downstream end of the sleeve/mandrel assembly. Since the drum, the mandrel and the sleeve all rotate with a common rotating movement, it is possible to select the direction and the speed of rotation of the latter three elements so that the helical article which comes out describes an exiting output translational speed, while exhibiting a null rotational value about its longitudinal axis.
