Abstract
A roller assembly positioned downstream of a printing station in a web-fed rotary printing press for pneumatically guiding a web of paper after it has been printed upon, without the risk of smearing the printings. The assembly includes a roller in the form of a hollow cylinder defining a plenum chamber therein and having formed in its surface a multiplicity of air outlet openings in communication with the plenum chamber. Air supplied under pressure to the chamber is therefore expelled from the air outlet openings in order to avoid contact with the roller the web traveling over the rollera baffle encloses at least part of the circumferential part of the roller surface for confining the air being expelled from said at least part of the other circumferential part of the roller surface and for redirecting the confined air into a pair of spaces, spaced, between the web and the roller.
