Claim 20:
21. A device for conducting a method according to claim 20, the device comprising: an extrusion plate having a plurality of extrusion openings; a collection container for taking up a coagulation bath; a deflection device arranged in the collection container for deflecting a filament bundle from the collection container; and a bundling device which determines a deflection width L occupied by the filament bundle on the deflection device; the extrusion openings are arranged within a length LL and the bundle of filaments occupies a deflection width L on the deflection device which is at least 80% of the length LL, and
the bundle of filaments occupies a deflection width Loutside on a deflection device provided outside the coagulation bath, which is controlled according to the formula:

L>(2×LZ×cos(B/2)×v2,5)/(10×ccell0,5×Q),

wherein Loutside is the deflection width of the bundle in mm, LZ is the number of extrusion openings, B is the deflection angle (calculated as 180° minus the wrap angle of the filaments around the deflection device in angular degrees), v is the speed of the filaments in meters per second, ccell is the cellulose concentration of the extruded fluid in % by mass and Q is a dimensionless load number, wherein Q is 300 or lower, and v is at least 35 m/min.
