arrow p 11 to mixer 4 compressed air and a bonding agent are supplied to mixer 4 via pipe 22 and pipe 23 respectively as a result of which the fibres present in mixer 4 are efficiently bonded to the bonding agent the fibres which are bonded to the bonding agent and which are provided with bonding agent are blown in the direction indicated by arrow p 12 into pipe 5 by the air flow produced by device 21 from where the fibres provided with bonding agent which adhere together by now are carried into defibering apparatus 6 the bonded together fibres are pulled slightly apart by the blade wheel 25 rotating about shaft 24 then the fibres are passed in the gap 29 between rollers 26 27 in the direction indicated by arrow p 13 rollers 26 28 are driven at different variable speeds as a result of which the bonded together fibres are pulled apart and carried in the direction indicated by arrow p 14 towards outlet 30 outlet 30 is located above the plate 39 comprising cells 40 and the fibres provided with bonding agent which have been separated from each other by defibering apparatus 6 will fall into cells 40 under the influence of the force of gravity base plate 39 is vibrated to and fro by means of vibrating devices 32 disposed under conveyor belt 31 as a result of which the fibres falling into cells 40 will move further in downward direction the fibres falling onto plate 38 are swept into cells 40.
