Abstract (en)

[origin: EP0484812A1] The present invention relates to an apparatus for manufacturing a web with multiple layers of randomised fibres and to the web obtained with this apparatus, in which a particular number of devices for taking up the fibres from the large drum (11) by means of "mechanical" systems (12, 17, 17', 20, 20', 18, 19, 22, 27, 27', 30, 30', 28, 29), such as the combing cylinders or the like, is combined with a device for taking up the residual fibres (31) from the large drum (11) by means of an air-suction system (21, 23, 25, 26), in such a way that the web or webs produced solely by the mechanical systems (12, 17, 17', 20, 20', 18, 19, 22, 27, 27', 30, 30', 28, 29) and the web produced solely by the air-suction system (21, 23, 25, 26) are formed on different conveyor bands and are subsequently superposed on one conveyor band (24), thus producing an exceptionally uniform web having multiple layers with extremely high randomisation and with the possibility of increasing its weight. <IMAGE>
