PROCESS AND APPARATUS FOR THE MANUFACTURE OF A NON-WOVEN FABRIC

摘要

Process for the manufacture of a non-woven fabric by spinning of tow in the form of a linear group of filaments forming a curtain from a plurality of spinnerets by aerodynamically drawing off and stretching of the tow, whereby the tow exiting the stretching channel or drawn off a reel is moved laterally transversely by an air stream of periodically changing direction whereby the air stream in a horizontal plane is oriented obliquely relative to the tow.
