Abstract

Apparatus for drying a travelling web, particularly a paper web. A hot air delivery structure is mounted adjacent the periphery of a steam heated cylinder to direct jets of hot air against travelling web supported on the cylinder. At least part of hot air delivery structure is moveable transversely of the cylinder periphery and the jets of hot air produce a surface effect to hold air delivery structure away from engagement with the web. Movement of hot air delivery structure is preferably achieved by flexure of that structure.
