ABSTRACT:
The present invention relates to gas treating apparatus for treating web-like or granular material conveyed through the apparatus, and more particularly to a novel nozzle arrangement for such apparatus which insures that a uniform, unbroken stream of treating medium impinges against the web-like or granular material. The present invention is particularly applicable to the transverse orientation of polymer film, the drying of particulate material, the drying or heat setting of films or fabrics, and other such applications where precise control of processing conditions is required.
