Definitions

  • The. invention concerns apparatus of the type above referred to comprising at least one group of spaced nozzle members through the orifices of which the active fluid (hot or cold air, saturated or superheated water steam, vapors, etc.) is forced under pressure to impinge upon the product to be treated, the intermediate spaces de-- fined by the walls of adjacent or sucessive nozzle members forming exhaust passages or canals which, in the case of an apparatus for the treatment of continuously moving sheet material, extend transversely to the path of travel of the material and serve to remove the spent fluid with the aid of a partial vacuum (subatmospheric pressure) created therein.

  • the purpose of the invention is to provide maximum efliciency in apparatus of this type, i. e. to enable, by means of'a group of blowing nozzle-members extending, opposite the treated product, over a given area, the highest output to be obtained while reducing to a minimum their consumption of treating fluid and of the power.
  • vide-means avoiding the formation of air or vapor cushions between the openings of the discharge noules and the material or product to be treated or dried, whereby a uniform treatment of the latter is obtained without disturbances usually occurring between the zones of fluid discharge and the zones of exhaust or evacuation of the spent treatment fluid.
