ABSTRACT:
Method and apparatus for continuous manufacture of a laminate comprising a layer of a conductive polymer and at least one electrode. A tape electrode and a heat-softened conductive polymer are fed simultaneously through an elongate aperture of substantially closed cross-section formed by a plurality of rollers, whereby there is produced a laminate in which the conductive polymer layer has a controlled cross-section. Preferably the electrode has a plurality of openings therein and is fed through the aperture so that there is at least one point on the electrode, as it passes through the aperture, which coincides with an angle which is formed by two of said rollers and which is at most 90.degree.. Particularly good results are obtained when the roller which contacts the electrode has a plurality of indentations therein, so that conductive polymer not only penetrates into the openings in the electrode but also passes through those openings which overlie the indentations in the roller. Novel laminates are produced in this way.
