ABSTRACT:
Apparatus for making an electret tape having an electrically conductive strip with a dielectric layer on one side thereof comprises tape supply and take-up reels arranged to move the tape from the former to the latter in an upwardly inclined plane and an electrostatic charging assembly between the reels having a dielectric fluid applicator for applying the fluid directly to the dielectric layer, a sponge-like electrode connected to a high dc voltage source, and an air blower for drying the fluid on the tape. The electrode is longitudinally spaced from the fluid application point in the direction of tape movement, engages the dielectric layer across its full width, and is wetted on the tape input side by the fluid on the layer. The blower is on the tape output side of the electrode with a baffle spaced closely to the dielectric layer between the blower and the electrode. This arrangement insures that the electrode is continuously wet and that the fluid is dried on the dielectric layer before the latter moves away from the electrode.
