Abstract
Control of the neutralization of surface charges existing on objects such as paper, fabrics, plastic sheets or the like. In order that the surface of an object (1) can be neutralized independently of the output parameters, the electrostatic charge present on the object (1) is determined by means of a charge sensor (2) arranged upstream of the brush. The charge already neutralized via the brush (5) is also continuously measured. The two values are fed to a microprocessor (11) causing an actuator (7) to control the brush-to-object distance. The controlled movement of the brush (5) effects complete neutralization.
