ABSTRACT:
Apparatus for compacting a nonwoven textile fabric mat is disclosed which includes an arrangement of rollers having a pair of juxtaposed rollers (2,3) and a superposed roller (4) arranged in a fiber compacting arrangement. Juxtaposed rollers (2,3) are spaced apart to define a space (9) in which central superposed roller (4) extends for compacting fibers. Perforations (5) extend through the surface of a shell (6) of each of the rollers. A first conveyor (16,19) conveys the textile fibers to the roller arrangement and a second conveyor belt (17,20) conveys the fibers away from the roller arrangement. Belts (19,20) may be perforated and surround rollers (2,3), respectively. Suction applied to the interior of the rollers assists in compacting the fibers in the mat as air is drawn through perforations (5) which are of a predetermined diameter and shape.
