Abstract
Air turn for supporting and optionally drying a web, comprising an arcuate surface having a plurality of apertures formed therein. Pressurized gas is supplied to the air turn plenum, and exits through the plurality of apertures to form a cushion of air to float the web. Turn angles of about 90° to about 300° with no contact to the web are achievable with the apparatus of the present invention. The unique semi-circular design allows for non-contact flotation and turning of a tensioned web with low pressure requirements, reduced air spillage and reduced noise level. Multi-chamber turns can be used with each section having independently controlled pressurized gas.
