Process for producing high-density woven fabrics on a water-jet loom, comprising feeding a warp having up to three catch threads on one edge, inserting weft threads into the warp in the direction of the catch threads, beating-up the weft threads to produce a woven fabric, severing the ends of the weft threads at the edges of the warp, and removing the ends of the weft threads, characterized in that, seen from both edges of the warp, 5 to 60 threads of the warp, following the catch threads on the edge of the warp with the catch threads, are support threads that are maintained at a tension that is 2 to 20 cN/tex higher than that of the threads forming the remaining warp, that after production of the fabric the weft threads between the edges of the remaining warp and the support threads are severed by fusion and joined to threads at the edges of the remaining warp, and that the severed ends of the weft threads are removed together with the support threads and the catch threads.
