APPARAT FOR TORRFORMNING AV EN BANA BESTAENDE AV PARTIKLAR ELLER FIBRER

摘要

Apparatus for dry-laying cellulosic fibres on a foraminous travelling band comprises a distribution chamber one wall of which facing the band is provided by a vibratable screen. Within the chamber is a rotating brush roll positioned so that the brushes cause the screen to vibrate. Fibres are urged through the screen partly by the action of the brush roll. Provision may be made for recirculating air which has passed through the band back to the chamber.
