Abstract
The present invention relates to an apparatus and a method as well as a system for extruding continuously molded bodies for producing filaments or staple fibers from an extrusion solution, such as a cellulose solution containing water, cellulose and tertiary amine oxide such as N-methylmorpholine N-oxide. In comparison with the methods known from the prior art, profitability can be increased in the production of continuously molded bodies () if the extrusion rate v is set to a value v=B·T·10,000·(1/r). In a system, profitability can be enhanced if the number r of rows is r=[(B/v)·10,000·T]. T is here the fiber titer in T dtex, v the extrusion rate in m/min, r the number of the rows of extrusion duct orifices (), and B an operational parameter which is not more than 4 and at least 0.5.
