<p>Method and apparatus are provided for effectively controlling cross-machine moisture profile in a paper web undergoing processing, such as water-removal via a press nip. A compartmentalized system is provided in close proximity across a section of a traveling web undergoing dewatering whereby select size cross-machine compartments, for example, about 6" in width, are selectively provided with steam and/or air so as to control wet and/or dry streaks along the traveling web so that web areas opposite each compartment can be selectively heated for accentuated moisture removal or cooled for retarded water removal. In preferred embodiments, control of this profiling system occurs with the aid of moisture sensors and a computer.</p> |
