Abstract
An apparatus for melt spinning multifilament yarns from fiber-forming polymers at wind-up speeds of at least 2,000 m/min, includes a spinnerette, a porous tube for solidifying the filaments, a convergence element for the filaments and a wind-up device. The apparatus further includes, at least between the spinnerette and the convergence element, an essentially vertical spinline. The porous tube is open in the spinning direction and concentric relative to the spinline.
