Apparatus for needling fibre web to produce a pile thereon is arranged with the web to be needled passing vertically downwardly from a pair of guide rollers to a take-up roll with a plurality of pairs of needle boards located therebetween. As the web passes between the pairs of needle boards which perform the needling operation, the take-up roll positioned therebelow is moved horizontally to accommodate web material accumulating thereon in order to maintain the location of the incoming web constant and accommodate build-up in the diameter of the accumulated web roll.
