Abstract
A process and apparatus for filling a generally tubular autmotive silencer casing with glass fibres are characterized by the feature of filling the casing from both ends simultaneously, preferably with the aid of spacer elements temporarily located on the ends of the casing during the filling step, any overflow of fibres into these elements being subsequently pushed into the casing to give a uniform density fill prior to installing end caps. The process/apparatus preferably also features bulking of the fibres by passing them through a specific jet configuration more than one of which may be used at each filling station.
