摘要： Manufacture of a non-woven web of man-made filaments in which one or more strands of filaments, directed parallel to each other, leaving one or more spinnerets are forwarded, each, by means of an air jet to a spreading plate for the filaments, and the resulting layer of spread filaments and air leaves the plate and advances to a moving support, upon which the filaments are deposited randomly to form a web which will then be bonded in known manner. In order to improve the isotropy of the web, the layer of spread filaments and air is guided to a fixed deflector plate forming a slit with the discharge edge of the stationary spreading plate, said slit allowing passage of the filaments but braking the air carried along with the filaments, and the layer is then subjected to an air jet directed transversely to the path of said deflected web and generally in a direction parallel to the surface of the moving support.
