Abstract (en)
[origin: EP0153100A1] A strand of fibres of a suitable silencing material, e.g. basalt, is chopped into discrete lengths by passing it between two rollers (12, 15) one (15) of which carries a cutter (14). The chopped roving is carried in an air flow, established by an air blast, air jet or a vacuum, into a silencer casing (1) via a restricted opening (10). The fibres <<fluff-up>> to a wool-like consistency as they pass into the silencer casing (1). The strand may comprise continuous or relatively short fibres and these may be twisted, plaited or laid parallel.
