ABSTRACT:
An assembly for use at the nip between a dryer fabric and a dryer bottom roll at a location at which the fabric moves onto the roll and at which the web to be dried is outside the fabric. A shroud having first and second walls which diverge from a nose is assembled with a plenum chamber body having downwardly converging walls with an opening between the lower ends. The upper edge of one wall of the shroud is secured to one wall of the body to form a first plurality of orifices with the nose of the shroud below the opening and with the other wall of the shroud extending upwardly along and in spaced relation to the other wall of the body. One edge of a baffle extending across the body opening is secured to the one wall of the shroud with the other edge of the baffle connected to the other body wall at a location below the upper end of the other shroud wall to form a second line of orifices.
