Abstract Capacitors are manufactured by winding a number of parent or master windings one upon another, coating the windings in common with metal on the face sides thereof by a metal spraying process and separating them one from the other. In one instance, the master windings are separated one from the other by the provision of inactive layers which project at the face sides or ends of the windings to prevent contacting of the layers of the windings during metal spraying. In another embodiment the interlayers are dimensioned as wide as the capacitively active layers and the face-side zones of the interlayers are masked during the application of the metallic layers. In yet another embodiment the inactive layers are completely metal coated and separation is provided by sawing or cutting in the zone of the interlayers. In this case, the interlayers remain on the finished partial capacitor as cover layers.
A process for the production of capacitors comprising the steps of: forming a plurality of stacked capacitor bodies by superposing for each capacitor body alternate metallic and dielectric films; disposing separating layers between the capacitor bodies contemporaneously with the superposed stacking of the metallic and dielectric films; applying a metallic coating to the edges of the stacked arrangement to connect the metallic films of the capacitor bodies; and severing the stacked arrangement perpendicularly to and parallel with the separating layers to form a plurality of individual capacitor bodies.

A process for the production of capacitors as set forth in claim 1, wherein the steps of forming stacked capacitor bodies and disposing separating layers between the capacitor bodies are further defined as superposing and disposing arcuate shaped films and layers, and the step of severing is further defined as cutting the stacked arrangement parallel to and within the separating layers and perpendicular to the separating layers in at least two directions, one of which directions lies in the direction of radius of curvature of the films and layers.
