Abstract (en)
[origin: FI20195076A1] The present invention relates to a method for producing solid cellulose filaments from a cellulosic fluid, comprising the steps of extruding said fluid through a plurality of extrusion openings, whereby fluid filaments are formed, and solidifying said filaments in a coagulation bath, wherein the filaments are bundled and deflected as a bundle in the coagulation bath in order to be drawn from the coagulation bath above the coagulation bath level, wherein the bundle of filaments occupies a deflection width L on a deflection device as defined by a formula, and to a device for conducting said method.
