Abstract

The long thin wires used for the corona discharge wires in electrostatic copiers are subject to self-excited vibration, when operated at high discharge rates. One technique for limiting the vibration amplitude is to stretch the wires very tightly. This technique has not been effective enough. It has been found that a small, light, loose fitting sleeve of plastic tubing positioned near one end of the corona wire will suppress the vibration very effectively.

Vibration Suppressor for Corona Wires

The long thin wires used for the corona discharge wires in electrostatic copiers are subject to self-excited vibration, when operated at high discharge rates. One technique for limiting the vibration amplitude is to stretch the wires very tightly. This technique has not been effective enough. It has been found that a small, light, loose fitting sleeve of plastic tubing positioned near one end of the corona wire will suppress the vibration very effectively.

The plastic tubing 1, functioning as a vibration suppressor, must be able to move freely in all directions transverse to the wire 2, and is preferably held in contact with the wire only by the force of gravity. The suppressor 1 is restrained from migrating toward the mid-span of the wire by stationary over-hanging portion 3. The occurrence of vibrations in the wire causes the suppressor to bounce lightly on the wire, resulting in the cancellation of the vibration through the inertia impact of the suppressor on the wire.
