ABSTRACT:
This invention relates to equipment for loading runs of fabrics with a gaseous treatment medium and being composed of nozzle boxes sequentially arrayed in the direction of advance of the run of material and extending transversely thereto, the boxes being supplied with the treatment medium which is blown out from orifices located therein against the material, a covering means mounted in each nozzle box above a slotted discharge nozzle and being of such a design that the covering means has a wavy profiled surface extending longitudinally parallel to the direction of jet and parallel to the longitudinal direction of the discharge nozzle, the wavy profiled surface forming a number of stop apertures above the discharge nozzle and perpendicularly thereto, the improvement comprising upper and lower partition means covering ends of the covering means which point toward side walls of the nozzle box, whereby the nozzle box is divided into an upper and a lower barrier space with the latter including at least one discharge nozzle, the upper partition means covering ends of the wavy profiled surface of the covering means open toward the upper barrier space, and the lower partition means covering an area extending beyond the ends and toward the center of the nozzle box of the covering means which is open toward the lower barrier space and the discharge nozzle, the partition means between walls of the nozzle box and the ends of the covering means forming lateral channels which connect the surfaces of the covering means which are open toward the upper and lower barrier spaces.
