Abstract
A take-off apparatus for plastic blown sheet that is collapsed has a deflecting roller rotatably mounted for transporting the blown sheet and an air turning bar for receiving the blown sheet from the deflecting bar along a transport plane defined therebetween. The blown sheet passes around a peripheral portion of the air turning bar thereby defining a support arc region of the at least one air turning bar about which the blown sheet is supported. The air turning bar has air outlet openings disposed in the support arc region through which compressed air is ejected to support the blown sheet. The air turning bar has an arc-shaped axis defining a plane of curvature which is oriented such that the peripheral portion presents a concave surface in which the air outlet openings are disposed and which opposes the blown sheet.
