  • Grounded magnetic device for removing static charges
    Patent number: 5331503
    Abstract: A device for removing static charges from a moving paper web includes two grounded and shielded permanent magnets with means to support each magnet on opposite sides of the moving web with the polarities of each magnet so oriented that the charge-neutral center plane of the magnet is perpendicular to the path of the web. The device removes static charges by exposing the paper web to a grounded magnetic field first of one polarity and then to a grounded magnetic field of the opposite polarity.
    Type: Grant
