ABSTRACT:
A method for producing a multifilament yarn by melt spinning of individual filaments which are grouped together to form yarn, in which, before winding, the yarn is subjected, in addition to the actual removal forces acting from the outside on the yarn, to further forces produced by gas streams which accompany the yarn in its longitudinal direction.
