Abstract
Static neutralizer for a tape dispenser in which a roll of tape is rotatably supported for drawing off selected lengths in strips comprises first brush means in juxtaposition with a surface of a tape portion radially peeled from the roll, second brush means in juxtaposition with an outer surface of the tape which has just been bared by the tape portion previously peeled from the roll, and a conductive path electrically interconnecting the first and second brush means, whereby any charges developed on the peeled-away portions of the tape are neutralized prior to dispensing. The respective brush means may be made of carbon or stainless steel fibers whose ends can be adjacently spaced from the corresponding charged surface thereby acting as an induction ionizer with respect thereto or in actual contact with such surfaces and defining a passive static eliminator.
