Abstract
A paper tube of a propeller tubeis made by winding a single faced corrugated fiberboardin which a wavy corrugating mediumis fixed to one side of a flat linerboardso that the corrugating mediumis oriented outwards, and the corrugating mediumcontacts with an inner surface of the propeller tubeso as to enhance a vibration controlling function. When winding the single faced corrugated fiberboardsince the single faced corrugated fiberboardcannot be wound in a direction oblique to a direction of ridges of the corrugating mediumthere are no fears that the shape of the single faced corrugated fiberboardis collapsed to taper axially, thereby it becomes possible to prevent a reduction in vibration controlling function that would otherwise be caused due to a change in the shape of the paper tube.
