Patent ID: 8617443

Claim:
A method of providing an edge of a starting sheet of an electrode with a dielectric strip of dielectric material, comprising: a positioning stage, wherein the edge of the starting sheet of the electrode is at least partly fitted in a die space; a feeding stage, wherein the dielectric material is fed into the die space; a melting stage, wherein the dielectric material is melted; and a solidification stage, wherein the dielectric material is solidified in the die space forming the edge of the starting sheet of the electrode, which is at least partly fitted in the die space, with the dielectric strip; wherein the dielectric material in the die space forming the dielectric strip, is pressed to the edge of the starting sheet of the electrode which at least partly lies in the die space during the solidification stage, and wherein the die space consists of several die parts, at least one of which is a movable die part, and at least one movable die part is moved with respect to the die space, so that the volume of the die space is reduced during the solidification stage.
