ABSTRACT:
The invention relates to a method of providing a lead to an end of a capacitor which is formed of two metal foils which are wound together and between which an insulating material is provided, in which at one end of the capacitor the edge of one foil projects from the edge of the other, and at the opposite end of the capacitor the edge of the latter foil projects from the edge of the former, viewed in the direction perpendicular to the longitudinal direction of the foils.
According to the invention the projecting ends of the foils are coated with a metal layer. Next, the end of a lead is pressed onto the metal layer at each end of the capacitor, while heating the lead and/or the metal layer. The said end has two substantially contiguous portions which are pressed against the outside of the metal layer and are interconnected by a connecting portion which is offset from the plane of symmetry of the contiguous portions and is pressed into the metal layer.
