Web flutter at circular-tube air-turn bars
Abstract
Circular tubes having air-emitting holes are often used for non-contact handling of photographic and magnetic media and for printed paper webs. One of the problems of circular-tube air-turn bars is their tendency to cause flutter, sometimes accompanied by a buzzing sound. An experimental study of such a flutter problem is discussed in this paper. Vibration of a web supported by air-turn bars was measured for different values of supply pressure of air, web tension, and wrap angle. It is shown that different types of flutter can occur at different operating conditions. This study resulted in parameter maps which show the regions of operating conditions for different types of flutter.
