Beschreibung
Zusammenfassung:	The invention relates to a method for producing elongated objects made of a plastic material, according to which the raw material is processed and plasticised to form a melt and said melt is then spatially and cross-sectionally deformed into a desired shape so as to yield a melt strand which embodies the object concerned. The melt strand is then possibly sized and/or cooled, whereby the final cross-sectional shape is determined. The raw material for the melt is prepared in accordance with the specific raw material used and independently of output. To obtain predefinable product characteristics for the shaped and hardened object, heat is supplied to the raw material, which is kneaded or sheared until a plasticised melt is obtained.
