Abstract

A web-processing apparatus comprises a dryer with air-turn apparatus for flotatingly supporting a web and, preferably, for changing a direction of web movement. The air-turn apparatus may be used in the web dryer or with other suitable web-processing equipment, particularly in applications where a coated web side faces the air-turn apparatus. Preferred forms of the air-turn apparatus comprise a body having an outer surface defining a web flotation zone facing a coated side of the web and a plurality of openings in the body positioned along the web flotation zone. An air-conducting conduit provides pressurized air to the body and body openings thereby forming an air cushion at the web flotation zone on which the coated web is flotatingly supported without contacting the body.
