Method of processing a fleece in a pre-needling apparatus, and an installation implementing such a method

摘要

A needle loom ( 2 ) for the consolidation of a fleece is preceded in the same installation by a pre-needle loom ( 3 ) having an "elliptical" movement, i.e. the needles ( 47 ) of which have a component of movement in the direction ( 6 ) of the progression of the fleece of fibres when they are in penetration phase in the fleece. The component is used as an additional way of propulsion of the fleece into the entrance to the needle loom ( 2 ).
