    (54) Method and apparatus for drying a coated strand


    (57) A plurality of coated strands (14) are conveyed through a drying oven (26). A plurality of nozzles (48) impinge the upper surface of the coated strand as it passes therethrough. Baffle plates (54) positioned below the strands redirect the gas stream such that, after the gas stream has passed through the strands, it is redirected so as to impinge on an opposite surface of the coated strand. The strand is supported by positioning it between an additional pair of nozzles (82) that are tilted towards each other such that an upwardly directed gas stream issuing from the first nozzle intersects an upwardly directed gas stream issuing from the second nozzle along a line which along with the strand, forms a generally vertical plane. The combined upwardly directed force from the gas streams lifts and supports the strand while the opposing lateral force from each gas stream on the strand tend to reduce and lateral movement and stabilize its relative position.
