Abstract: A steam distributor for applying steam to a continuously moving paper sheet employs one or more drop-out steam profiling cartridges. Each cartridge is connected to a steam distribution apparatus and includes a number of profiling zones that are covered by a contoured, smooth profiling screen from which steam is applied. The profiling screens are welded to baffles which enhances the structural integrity of the cartridge. No external clamps or other devices are employed that would otherwise disrupt the smooth, curved exterior surface of the profiling screens. The spaced-apart baffles also eliminate the spilling over of steam from one profiling zone to the next which has the effect of minimizing the response width for steam profiling control. The use of the drop-out cartridges permits quick and easy removal of the profiling screens for change-out or cleaning.

Abstract: A web dewatering concept which has particular utility in papermaking processes wherein overall compression and compaction of the paper web by mechanical means is avoided comprising a high pressure jet of compressible fluid such as air or steam emitting from a slot extending across the entire width of the web. The web is constrained between a pair of foraminous supporting members while it is passed across a slotted nozzle expelling a jet of compressible fluid at pressures up to about 50 psig. The jet of compressible fluid scrubs the free water from the spaces between the fiber matrix of the web and the foraminous supporting members. The edges of the slotted nozzle make intimate contact with and form a seal against the interior surface of the foraminous supporting member closest the nozzle. This causes direct penetration of the web and the carrying members by the fluid jet, thereby continuously expelling an atomized stream of moisture from the web.
