A method of, and equipment for gathering fibres entrained a gas stream, for example by melt blowing, comprises an enclosure having an inlet, through which a gas stream carrying entrained fibres may be directed into the enclosure, a fibre outlet from which an assembly of gathered fibres may be withdrawn from the enclosure and an exhaust outlet through which gas may pass out of the enclosure. The enclosure is constructed to provide a pathway for the fibres from the inlet to the fibre outlet in which surplus gas in the gas stream is separated from the entrained fibres and directed to the exhaust outlet, thereby reducing turbulence in the fibres in the enclosure which may affect the quality of the finished assembly.
