ABSTRACT:
Apparatus for directing steam against one side of a running web of fibrous material has a housing defining one or more steam chambers and having walls which surround the chamber or chambers. One of the walls is apertured and is located at the path for the web to direct jets of steam toward successive increments of the running web. The steam is dried prior to admission into the chamber or chambers via one or more adjustable valves, and at least one wall of the housing is heated by dried and/or undried steam in order to reduce the likelihood of condensation of steam in the chamber or chambers.
