ABSTRACT OF THE DISCLOSURE The present invention provides a process for the manufacture of a pile fabric by severing a selection of yarn strands appearing on one of the faces of at least one sheet of fabric, in which the severing is performed by means of a focused laser beam, characterised in that the zone of focus of the said beam is brought successively into contact with a determined portion of each of the said strands, on each occasion for a period of time sufficient to cause combustion of at least part of the fibres forming said strands. The present invention also provides a device for the production of a pile fabric including means for producing a focused laser beam; guide means for successively placing the zone of focus of the beam into contact with the determined port- ions of strands, a selection of yarn strands appearing on one of the faces of at least one sheet of fabric, and drive means for moving the focus of the beam relative to the said determined strand portions.
