A facility for needling a patterned width of felt 1 comprises, at least two independently driven needle boards 6, 7, a continuous felt bed 9 and e.g. a holding down device 12 positioned between the needle boards 6, 7. The felt bed 9 may be comprised of slats or a continuous circulating brush type bed. The needle boards 6,7 are provided with different arrangements of needles allowing a range of patterns to be produced. For example the felt may be provided alternately with the patterns of needle boards 6 and 7. A further embodiment comprises more than two needle boards 6,7 allowing a greater range of patterns to be produced.
