Apparatus to supply steam to a paper sheet moving beneath it. The apparatus has a leading edge and a trailing edge relative to sheet direction. It has a header and there is a supply of steam to the header. A chamber is positioned adjacent to the header. Steam can be transferred from the header to the chamber. A heating zone is defined beneath the chamber to be generally adjacent to the paper sheet when the apparatus is in use. Outlets in the chamber permit steam to pass from the chamber to the heating zone. Exhaust manifolds positioned adjacent to the leading edge and the trailing edge of the apparatus permit excess steam and vapor to be drawn away from the heating zone.
