PROTECTIVE JACKET FOR LEAD ACCUMULATOR'S ELECTRODE,METHOD OF ITS PRODUCTION AND EQUIPMENT FOR APPLICATION OF THIS METHOD

摘要

A boxed plate lead battery electrode characterized in that it is closed on two sides by a respective planar wall 31, 32 continuously bounding all separator compartments between the side walls 38 connecting the two planar walls. The side walls 3 of the compartments are arranged in parallel with the side walls 38 so that they form diaphragms made from strips or threads. The process according to the invention may use fabric or web material. In the case of a fabric-based product the thread walls forming the diaphragms are woven 'in space' into the two continuous walls 31, 32 while the latter are maintained at a height difference corresponding to the thickness of the plate, while in the case of a web or tissue-based product, the two continuous walls are laid one upon another and the side walls 3 corresponding to the compartments are formed by stitching together the two continuous walls with loose stitches employing excess thread of a length chosen in accordance with the desired air gaps in the diaphragm.
