Abstract
1. A method of forming a felt of fibres in which the fibres are formed from a material which is in the drawable state, this material being carried over the peripheral surface of one or more wheels to which a rotary movement is imparted and from which the fibres become detached and are thrown into a gaseous current which is directed transversely of the direction in which the fibres are thrown and along the peripheral wall of the wheel or wheels, the fibres thus formed, entrained by the gaseous current, being carried into a receiving chamber in which the base is constituted by a perforated conveyor, the gaseous current carrying the fibres crossing the conveyor, the fibres becoming deposited on the conveyor in order to form the felt, the method being characterized in that one or a plurality of additional gas jets are created on either side of the gaseous current carrying the fibres substantially in the same direction as that of the current, these additional jets being emitted along lateral walls bordering the perforated conveyor.
