Static brushes suitable for handling electric charges so as to obtain static electricity control including static discharge in web handling devices such as printers, presses, xerographic copiers and other film and paper handling equipment is made of conductive thread wound in continuous turns around a mandrel and slit to form open-ended loops forming the brush bristles. A continuous element or elements, such as a wire or wires, may be placed on the mandrel and the turns are wound thereon. Strips of pressure-sensitive tape are adhered along the sides of said loops and encompass the element(s) so as to hold the loops and elements assembled as unitary brushes, which may readily be installed in equipment requiring static control by removing releasable paper over pressure-sensitive material on the outside of these strips. Double-sided pressure-sensitive adhesive tape may be used in constructing the brushes. The continuous elements (wires) prevent release of the threads of individual loops from the brushes when pulling forces are applied to the bristles. The mandrel is an endless loop on which thread winding, wire placement and pressure-sensitive adhesive tape application may be carried out progressively as the endless mandrel rotates. Effective, both operationally and in cost, static brushes are thereby provided. |
