Abstract
A steam shower to supply steam to a web passing beneath it. There is a main supply header and a preheat chamber enclosing the main supply header. The steam is proportioned between the preheat chamber and the main supply header. There are at least two chambers to receive steam in sequence from the main supply header. In a preferred embodiment the at least two chambers are divided into compartments along the length of the shower. Profiling valves control flow from the main supply header to the first chamber in this preferred embodiment. There are outlets in the last of the at least two chambers through which steam passes to the web.

A steam shower to supply steam to a web passing beneath and comprising:
- means defining a steam supply;
- a main supply header;
- a preheat chamber enclosing said header;
- pipe means to direct steam from the steam supply to the preheat chamber on the one hand and to the main supply header on the other hand and means located in said pipe means to proportion steam flow between the preheat chamber and the main supply header;
- at least first and second chambers independent of the preheat chamber and arranged to receive steam in sequence from said main supply header;
- and
- outlets in the last of the at least first and second chambers through which steam passes to the web, said outlets being adjacent to at least one exterior wall of the preheat chamber and structured and arranged so that steam leaving the outlets is heated by contact with the at least one exterior wall of the preheat chamber.
