Abstract
A web handling device through which a web is arranged to pass along a tortuous path extending around a number of rollers includes means for threading the web pneumatically comprising, in association with at least one of the rollers, a guide member having a guide surface which extends around part of the periphery of the roller in a spaced relationship so as to define a passage for the web, means for directing the web approximately tangentially towards the guide surface, and an air mover mounted on or adjacent to the upstream end of the guide surface, and arranged to pass a moving film of air along the guide surface while the web is being threaded through the apparatus, so as to entrain the web and convey it around the roller.
