    摘要: The current invention relates to continuous process for the production of a multitubular gauntlet, said process comprising the steps of: continuously providing at least one sheet of fabric with two lateral edges; overlapping two lateral edges; seaming said overlap by welding or gluing, forming a closing seam wherein both lateral edges are joined together creating a tubular fabric, seaming said tubular fabric along seams parallel to the closing seam, thereby forming flat tubes parallel to the closing seam; and thermoforming the plurality of flat tubes into the desired shape corresponding the electrode to be used, thereby obtaining the multitubular gauntlet. The invention further relates to a multitubular gauntlet for lead-acid batteries comprising at least one sheet of fabric with two lateral edges, said fabric forming a plurality of parallel tubes, wherein at least one lateral tube forming the edge of said gauntlet comprises an overlap of said lateral edges, wherein said overlap is seamed by welding or gluing.
