<p>The appts. to give a non-woven material has a fibre loosening roller (1) to separate the fibres with a centrifugal effect, to spin them out and form an initial fibre layer. An air feed channel (19) is between the fibre loosening roller (1) and the shrouding (18) covering the fibre movement zone at the roller peripheral direction, across the working width. It delivers an air stream (20) against the direction of roller (1) rotation.</p> |
