ABSTRACT:
Apparatus for continuously producing an elongated composite tape transducer having an inner laminate with a conductive dielectric-covered strip and two outer laminates each with a conductive foil comprises two reels containing the outer laminates and one reel containing an inner laminate, a station for electrically charging the dielectric layers on opposite sides of the inner strip, a mold for applying and sealing the outer laminates to opposite sides of the inner laminate to form the composite transducer, and a mechanism for pulling the three laminates through the apparatus. The lead end of the inner strip is electrically grounded. The charging station has two electrodes connected in parallel to a source of high DC voltage and physically positioned to make electrical contact with the dielectric layers, respectively, on opposite sides of the inner strip. The mold has a pair of heated plates which seal the preheated side edge portions of the outer laminates together around the inner laminate to complete the fabrication operation. The completed transducer is pulled through the charging station and mold by a drive mechanism which frictionally engages substantial lengths of the marginal edge portions of the outer laminates with low unit pressure to prevent damage to the transducer.
The invention also comprehends the method of continuously making the composite tape transducer consisting of the steps of electrically charging dielectric layers on opposite sides of a conductive inner strip to form electrets, applying wider outer laminates symmetrically to opposite sides of the electret-covered inner strip and sealing together the marginal edge portions of the outer laminates to enclose the electret-covered inner strip.
