ABSTRACT:
A steam distributor for applying steam to a paper sheet moving beneath it and spaced from the distributor. The distributor has a leading edge and a trailing edge relative to the sheet movement. There is a header for steam extending along the leading edge. At least one opening formed in the header enables steam to be directed towards the sheet. The steam so directed forms a curtain to eliminate air entrained by the sheet.
