ABSTRACT:
A polymer material in liquid form is continuously extruded through the spinning nozzles of a spinning head to thereby form filaments which drop downwardly through a blowing shaft positioned beneath the spinning nozzles. The filaments are entirely cooled, solidified and recrystallized during passage of the filaments through the blowing shaft. A drawing off roller in the form of a guide roller is located at the lower end of the blowing shaft to draw the filaments laterally from the blowing shaft, over a guide roller, and substantially vertically downwardly from the guide roller to a winding machine whereat the filaments are wound up. The winding machine is preferably located laterally of the blowing shaft, with the guide roller positioned at a level which is higher than the level of the drawing off roller. Thus, the filaments move from the drawing off roller to the guide roller in an upwardly inclined direction. The filaments are subjected to any necessary moisturizing and/or treatment operations during the passage of the filaments downwardly through the blowing shaft.
