Abstract
Synthetic filaments having a circular cross-section are manufactured by melt-spinning from spinneret openings having likewise a circular cross-section which are provided with lateral arms distributed over their circumference and ending in the circular cross-section area at an about right angle. The lateral arms need not cover the complete length of the spinneret holes, but only the outlet opening of the spinneret holes.
