ABSTRACT OF THE DISCLOSURE: The invention concerns the improvement of the fiber distribution in a web or mat, the attenuation of the fibers being effected by means of gas currents. The material delivered in the form of filaments is attenuated in a channel between two gas jets. At the outlet of the channel, the gas current carrying the fibers entrains the ambient air and passes through a guide appa- ratus containing two walls. The circulation of the air induced between the channel and the guide apparatus is modi- fied by the interposition of baffles . The modification provides for improvement in the uniformity in the fiber web being made.
