Abstract

A nozzle device for the manufacture of hollow synthetic fibers or staple fibers, based on linear polycondensation synthetic products or polymerization products, which is provided with one or more slit-shaped spinning holes, each spinning hole consisting of two or more arc-shaped slits that in combination partially surround a section of the nozzle while the distances between adjacent slits vary between 1 and 6 times the width of the slits; characterized by said nozzle device in that the grooves, in combination, partially surround a surface area of 0.1 to 7 mm2, and that the ends of the adjacent grooves run parallel each.
