  • Method and device for spraying fluid into a headbox
    Patent number: 3933966
    Abstract: In a device for feeding fiber suspension to the web-forming part of a paper machine the tendency of the fibers in the suspension to flocculate and form fiber clusters, before being fed onto the web-forming wire, is eliminated by spraying jets of water or steam or both into the head box which is supplied with a fiber suspension of a consistency greater than the desired. The jets cause strong turbulences in the head box and thereby effectively disperse the fiber clusters.
