nature of the fibres to be worked and the quality of the produce to be obtained for the majority of the fibres to be worked it is absolutely essential to plan for several successive passages over spiked drums in the known modern machines the number of feed systems spiked drums and layering devices has therefore been multiplied the layer of fibres passing automatically from one spiked drum to another without manual intervention the present invention has the main aim of allowing several passages of the fibres through the same disintegrator module the handling of the fibres and the setting changes appropriate to each passage of the fibres being carried out entirely automatically there is shown in fig4 a machine according to the invention this machine essentially comprises a disintegrator module 10 in which the fibres to be treated are carried by a feed device comprising a conveyor belt 11 a supple roller 12 and a trough 13 to a spiked drum 14 a fibre layering device 15 which comprises a perforated drum 16 of which the internal space is kept in depression by means of a suction device and which is remote from the disintegrator module 10 a suction channel 17 to carry the fibres from the disintegrator module to the layering device 15 a storage shaft 18 which extends below the layering device 15 to receive the layered fibres a conveyor belt 20 which collects the fibres from the bottom of the regulating shaft 19 to carry them towards the feed device of the disintegrator module a central control device which regulates the different components of the machine these.
