An electrical capacitor is formed utilizing a thin dielectric layer which is metallized on both sides to provide electrode areas. The capacitor is formed by pleating, or folding, the dielectric layer along its longitudinal dimension an odd number of times. The pleats are not creased but are allowed to...http://www.google.es/patents/US4146914?utm_source=gb-gplus-sharePatente US4146914 - Pleated metallized film capacitor with staggered edges
