Abstract
An apparatus and method are disclosed for continuously cooling a hot printed traveling web in order to set the ink thereon. The apparatus and method include a frame and a chill roll rotatably mounted thereon having a peripheral surface. A pressure roll is rotatably mounted on the frame and has a pressure applying surface in contact with the chill roll peripheral surface to define a web receiving nip. The printed web is passed into the nip. Liquid coolant is applied to the peripheral surface of the pressure roll prior to its entering the web nip during which time the pressure roll is cooled. A metering roll is rotatably mounted on the frame to place its peripheral surface in contact with the pressure applying surface to define a metering nip. The pressure in the metering nip is adjusted so that only a predetermined amount of coolant liquid remains on the pressure roll peripheral surface for contact with the web.
