Abstract

A device for guiding web material in a required path, comprises a pair of guide surfaces 4 and means adapted to generate an air curtain 11', 11'' over the guide surfaces, e.g. using the coanda effect, guide surfaces extending in axially parallel relation transversely on one side of the required path, being disposed adjacent to the path, and being oriented so as to create an air pressure reduction in a zone 2 between the guide surfaces. In use, web material is retained adjacent to the guide surfaces by the air pressure reduction in the zone whilst being spaced from the guide surfaces and transported along the required path by the air curtains. <IMAGE>
