ABSTRACT:
An oscillating hauloff device for removing blown film from an extruding apparatus. The oscillating hauloff includes a stacked ring arrangement which provides a compact and stable structure. The turning bars and idler rolls are encompassed in the ring structure and are arranged to cancel effects of web wandering and wrinkling. A method for making the oscillating hauloff, including CNC machining of annealed ring-shaped weldments, that is economical and simple to manufacture. The turning bars are provided with reinforcements that prevent deflection of the turning bars during use. Further the turning bars are provided with flow restricted outlets and axially extending channels to supply uniform air pressure to float the blown film on the turning bars. A specific arrangement for providing utility services to the oscillating hauloff is also disclosed which employs torsional deflection of the loads during rotation of the rings. The oscillating hauloff is suitable for receiving film extruded downwards with only minor adjustments in structure from the unit for upwardly extruded film.
