ABSTRACT:
Apparatus to supply steam to a paper sheet passing beneath it. The apparatus has a leading edge and a trailing edge relative to the sheet direction and comprises at least two headers, a first header being adjacent to the leading edge. There is a steam supply system means for the headers. A profiling chamber is formed between the headers and baffles which divides the profiling chamber into compartments. There is provision for a controlled supply of steam to each compartment. Outlets in the profiling chamber permit steam to be projected towards the sheet from the compartments. A further chamber is formed adjacent to the leading edge and steam can be supplied to the chamber. Outlets in the further chamber permit steam to be directed towards the sheet to form a steam curtain at the leading edge of the apparatus to prevent air being drawn under the apparatus by the sheet.
