摘要

Manufacture of a non-woven fibre fleece material, where the fibres are transported through a passage by air into which a fungicide or a flame-retardant impregnation agent is sprayed. An Independent claim is also included for an assembly with a fibre feed (1) and a fibre-drying and distribution drum (4). The fibres are supplied via a spray (12) impregnation passage (7) to an air-permeable sieve (8, 9) where the fibres are trapped and later surrendered as fleece (11). The spray jets are arranged preferably in two rows.
