In an apparatus for feeding a fiber fleece web to a needling machine, a compacting means is arranged between a pre-compressor and a supply roller pair, said compacting means having rollers provided with teeth at their circumference. These rollers compress the fiber fleece and effect a partial re-orientation of the fibers from the horizontal into the vertical, which contributes to substantially maintaining the compacting of the fiber fleece. The compacting means may together with the supply roller pair form a drawing zone for the fiber fleece web. The compacting means preferably includes at least one roller triple that consists of two lower rollers arranged at a low mutual distance in juxtaposition, and upper rollers bridging over the gusset between the lower rollers. The rollers of the roller triple are provided on their periphery with all-steel armaments, and the supply rollers are preferably also provided with all-steel armaments and have higher speeds of rotation than the rollers of the roller triple. In an alternative embodiment, the means comprises at least one roller provided with all-steel armaments an a trough opposing the roller, said trough forming with the roller a gap narrowing in the direction of rotation of the roller. In this gap, the fiber fleece web passed between the roller and the dent is clamped. The discharge end of the gap opposes the supply roller pair, which is preferably driven at a high speed of rotation than said roller that opposes the trough.
