ABSTRACT:
An apparatus for transferring heat from a web includes a chill roll having a cylindrical outer side surface. The web moves along a path which extends part way around the chill roll. A nozzle extends between opposite edge portions of the web and extends circumferentially around a portion of the cylindrical outer side surface of the chill roll. A central portion of the nozzle directs a flow of air against a central portion of the web upstream of a location where the web normally engages the chill roll to deflect the central portion of the web into engagement with the chill roll. Opposite side portions of the nozzle extend away from the central portion of the nozzle and extend downstream from the location where the central portion of the web is deflected toward the chill roll. This results in a smoothing action which extends across the web and downstream along the web from the central portion of the web.
