be explained in the remainder of the description the meshes 4 are made by means of needles 5 which are moved in a predetermined way the decorative effect 3 is obtained by means of a decorative weft 6 formation of the basic backing by means of the warp and weft system is carried out in an entirely conventional way in combination with a comb or reed p but it is not described in detail because firstly this technique is perfectly well known to a person skilled in the art and secondly it is not part of the specific object of the invention the bonding needles 5 for forming the locking mesh 4 are disposed very substantially at right angles to the warp lap or shed 2 and are fixed to a base block 15 or needle bed which is moved in vertical alternating motion in accordance with the process of the invention when the comb p is drawn away from the beat up position the needles 5 advance parallel to the warp and rise perpendicularly across the warp yarn lap 2 of the basic backing when the needles 5 descend and disappear below the warp yarn lap 2 of the basic backing they.
