ABSTRACT:
The moisture content of a web of newsprint paper which runs from the drying unit to the collecting station of a paper making machine is increased in several stages by atomized water issuing from rows of spraying devices followed by cylindrical members which distribute the particles of water in the material of the web. The rate of water discharge from each spraying device is adjustable so as to compensate for eventual differences between the moisture content in the marginal portions and the moisture content in the median portion of the web.
