A turning bar draw-off device for a tubular film extrusion installation, with a plurality of turning bars which can be rotatingly driven around a common axis of rotation or in reverse by rotary drive mechanisms. For the rotating or reversing guidance of the turning bars around the axis of rotation, the ends of each turning bar are connected with guide carriages, which are guided on guide rails arranged in a circle.
