Disclosed is a steam-shower apparatus and method including a supply of steam which is fed through a Coanda nozzle and along a path running parallel with one surface of the apparatus. The sheet to which the steam is to be applied runs parallel to this same surface of the machine, but in a direction opposite to the direction of the flow of steam. The sheet travels along a path spaced slightly from the surface of the machine, and the flow of steam runs the entire length of this surface heating the sheet as it flows in the opposite direction. The apparatus may be divided into several sections so that the sheet may be profiled along certain regions which are defined by these sections. In addition, means are included for altering the volume of flow to any one of the particular sections.
