ABSTRACT OF THE DISCLOSURE A method and apparatus for the application of a sizing composition or the like to a traveling web under high speed conditions which involves passing the web into the nip formed between two counter-rotating rolls and supplying a sizing composition to the nip to thereby form a pond of sizing material on both sides of the traveling web. Additional amounts of sizing material are constantly being supplied to the ponds by means of a suitable applicator and nozzle arrangement, while the depth of the ponds is controlled continuously by the application of a reduced pressure to the existing ponds resulting in some of the sizing composition being drawn up into the applicator from where it is delivered to a reservoir for further circulation through the applicator.
