Abstract
Apparatus to supply steam to a paper sheet that passes by the apparatus from a leading edge to a trailing edge of the apparatus. The apparatus is adapted to be positioned adjacent the nip of two rolls and comprises a first header for steam and a first chamber to receive steam from the first header. Passages for steam are formed between the first header and the first chamber. An outlet in the first chamber permits steam to be forced against the paper sheet adjacent the leading edge of the apparatus to form a steam curtain to reduce the amount of air drawn under the apparatus by the paper sheet. A second chamber receives steam from the first header. There are passages for steam between the first header and the second chamber and outlets in the second chamber so that steam may be forced against the paper sheet to heat the sheet. The flow of steam along the length of the apparatus can be controlled.
