ABSTRACT:
An oscillating hauloff for blown film has a bearing structure positioned along the vertical process centerline. The bearing structure is separated into upper and lower sections to maintain a clear and open pathway for the web to pass across the process centerline. Passing the web across the process centerline allows the web to change directions before passing over a second turning bar, thus canceling any web wandering introduced by a first turning bar.
