    (57) The invention relates to an apparatus for supporting a strand or a plurality of strands comprising:
    pairs of first and second spaced apart nozzles (94, 96) wherein each of said pairs of nozzles (94, 96) are tilted generally towards each other such that a generally upwardly directed gas stream issuing from said first nozzle (94) of each of said pairs of nozzles (94, 96) intersects a generally upwardly directed gas stream issuing from said second nozzle (96) of said pair along a line; means to support said nozzles (94, 96) in a generally inclined orientation; means (76) to allow delivery of pressurized gas to said nozzles (94, 96) wherein said line of intersection between gas streams from each of said pairs of first and second nozzles (94, 96) and a strand (14) positioned between each of said pairs of nozzles (94, 96) each forms a generally vertical plane.
