ABSTRACT:
Battery plate envelopes include a sheet of porous film material having a folded widthwise bottom edge and overlapped lateral edges to thereby form a pocket for receiving a battery plate therein. The overlapped lateral edges are joined to one another by a lengthwise extending series of discontinuous joining regions with adjacent ones of the discontinuous joining regions being separated by respective unsealed regions. These unsealed regions thereby establish respective lateral channels through which fluid (e.g., electrolyte employed in a wet storage battery) may pass to the interior pocket, and hence to the battery plate. The discontinuous joining regions are most preferably formed by passing the sheet material through the nip between opposed joining rings, each of which is provided with a series of triangularly-shaped teeth with smooth land areas formed between adjacent teeth series.
