(57) Abstract An article manufactured from ceramic fibres, glass fi- bres or mineral fibres or a mixture thereof includes randomly directed discontinuous fibres formed of such materials and brought together with a dry process by means of an air flow, and possibly includes also a binder for binding these fibres. In a method for manufacturing such an article, the dis- continuous fibres, possibly intermingled with fibres serving as a binder, are couched into a mat in a manner that the discontinuous fibres are advanced into contact with an air flow which carries them to a level (36) so that the fibres become randomly directed and said fibre- carrying air flow is passed through said level (36). An apparatus for implementing the method comprises a web-forming unit (D) provided with a level (36) consist- ing of an air permeable wire or the like as well as feeder means (33) for advancing the fibres into a space (37) aligned with said level and connected with a flow duct (41) for passing the fibre-carrying air flow into said space.
