Abstract
A chill roll assembly for a printing press scrubs away boundary layers of air and vapors adhered to both side surfaces of a paper web moving through the chill roll assembly. The chill rolls are supported on separate frames which are adjustable relative to one another. Adjustment of the frames moves the chill rolls into and out of positions in which surfaces of the web sections moving in opposite directions around the rolls are held in closely spaced relationship to define a zone of interference. The boundary layers adhering to the closely spaced surfaces of the moving web sections are scrubbed away in the zone of interference.
