ABSTRACT:
An insulation sleeve for the can-shaped soluble anode of a round galvanic primary cell, which immobilizes emerging electrolyte and shields retained moisture from the exterior, and which electrically insulates the electrode conductor, includes a helically wound paper web having a plastic lining on one side and a lengthwise paper edge which is endlessly folded over, and which is wound onto a winding spindle so that the folded-over edge helically overlaps the opposite edge of the paper web to allow the superimposed plastic layers to be welded to one another in the overlapping zone. By successively winding a conventional paper strip with the plastic-lined paper web, an even stronger sleeve tube is obtained, which can then be cut into individual sleeves.
