Abstract
Disclosed is an apparatus for controlling the caliper of a web, such as a continuous paper sheet issuing from a nip of a plural-roll device, such as a calender. One or more rolls of the device is subjected to a multiplicity of air jets issuing substantially at constant flow rates but at temperatures which may vary as desired from nozzles spaced lengthwise of the roll.
