A method of charging insulative material includes applying a high voltage to a conductive plastic having a uniform resistance throughout. Insulative material is placed in proximity to, or in contact with, the conductive plastic, thereby charging the insulative material. Further, a device for placing charge on an object proximate to the device includes a conductive plastic having a uniform resistance throughout. A high voltage power supply has an output coupled to the conductive plastic.

Method and apparatus for charging or neutralizing an object using a charged piece of conductive plastic

A static neutralizing roll follower includes a static charge dissipating device on a carrier movably held by a support. Sensors follow the changing diameter of a roll, and a control unit processes signals from the sensor to operate a drive mechanism to move the carrier with respect to the changing roll diameter. Consistent spacing is maintained between the dissipating device and the roll surface.
