R. Vyse et al., Trends towards, finer cross-direction moisture profile correction - Systems with CD resolutions of 25-mm are achievable, PULP PAPER, 102(11), 2001, pp. 36-40
The desire for improved CD moisture profiles has led to the use of profilin
g steam showers and remoisturizing systems with CD zones widths of 75 mm or
less. This paper will review the application of narrow zone steam showers
and the development and use of a new air atomized remoisturizing system tha
t allows narrow zone resolution without sacrificing flow range. Typical res
ults from this novel nozzle design, based on laboratory and mill studies, w
ill be presented.
