A process for the manufacture of non-woven webs of continuous filaments by extrusion, stretching, deflection and deposition of a bundle of filaments on a receiving table and executing a reciprocating movement in a direction transverse to the direction of advance of the receiving table, is disclosed. Also disclosed is an apparatus for carrying out that process, for applying a reciprocating movement to the filament deflection device, comprising first, a tube in two parts, through which the filaments travel, having a fixed part and a movable part one end of which slides in the fixed part and the other carries the deflection device, and, second, means for subjecting the movable part of the tube, held parallel to the table which receives the filaments, to a reciprocating movement.
