Abstract: An electrical capacitor and manufacturing method therefore provides at least two dielectric bands each with a metal coat on at least one side to form stacked film, or wound capacitors. Changes in capacitance which are the result of fluctuations in dielectric ply thickness are compensated by corresponding opposite modification of the overlap of the layers. The compensation ensues by a de-metallization device that makes the metal coating wider or narrower on the basis of a control direction depending upon greater or lesser ply thickness.

Abstract: Method for the manufacture of layer capacitors, which includes winding a plurality of mother capacitors wound from at least one capacitor foil on a drum on top of each other, winding a turn of a cover foil packet formed of cover foils and a separating foil on each mother capacitor and having a gap between the beginning and the end of the turn of the cover foil packet, winding value foils through the gap and toward the mother capacitor on top of the gap, winding a holding foil with increased winding tension into at least the last wound value foil layer to place the cover foil packet under the holding foil with a shift in phase, continuing to wind the holding foil with the value foil through the gap for more than one turn, and cutting off the holding foil.

Abstract: An economical means for manufacturing stack or layer capacitors is disclosed wherein a metallized synthetic material band is separated lengthwise into films of the width needed for a capacitor, and by turning these films 90.degree. by means of appropriate rollers and laying them on top of one another on a collecting plate or a collection disk and then further processing them as a film packet unit into capacitors.
