Abstract
Methods and apparatus for transporting a flexible substrate are provided. In one embodiment, an air turn is disclosed that includes a body, a porous cover disposed about a circumference of the body, and two seals. Each of the two seals are positioned about the circumference of the body and spaced apart from each other in a longitudinal direction of the body to define a central zone bounded by a second zone and by a third zone. The second zone and third zone are each positioned outside of a respective seal. The body includes a first opening formed along a longitudinal axis of the body, and a plurality of second openings formed in the body at a position other than along the longitudinal axis.
