Abstract: A mat is produced from a single length of rope or other flexible member using a holder assembly which releasably clamps an end of each of a plurality of hollow tubular members. Warp lengths are formed over the clamped tubular members by alternately weaving the lead end of the flexible member over and under adjacent tubes, thereby forming respective groups of aligned loops thereon, until a desired width is obtained. The ends of the tubular members are unclamped from the holder assembly and weft lengths are formed by pushing or drawing the flexible member through the tubular members. A tube is removed from its position within a corresponding group of aligned loops when the pushed lead end emerges therefrom. The ends of the flexible member are wedged alongside a respective weft length to prevent unravelling of the mat.
