Definitions

  • the invention relates to a process for the production of metal fabric plates with tubular cells, in which a metal fabric web is produced with alternately single and double woven fabric strips, so that parallel, flat cells separated by longitudinal composite strips arise, and then plates of a certain size and with a a certain number of cells are cut out of the metal fabric and finally the flat cells ' on the plates are expanded into tubular cells.
  • Me ⁇ tallgewebeplatten serve • tubular cells spielnem in alkaline storage batteries as a carrier of the active mass ⁇
  • the object of the invention is to manufacture metal fabric plates with tubular cells in train to improve the method step mentioned so that the disadvantages described are avoided.
  • the edge strips formed on the plates can be unfolded with relatively simple means, and at the same time all cell openings along the plate edge in question can be exposed.
  • the edge strips can additionally be grasped and pulled away from one another so that the initially slit-shaped cell openings widen somewhat so that the spikes can be inserted into the cells unhindered to expand them.
  • edge strips of the same width are formed on adjacent plates, and each cut plate has such edge strips on two opposite sides, with the aid of which the cells can be opened either at their two ends, if necessary, or simultaneously v / earth.
  • the cells can already be closed on one side during the production of the metal fabric web.
  • the method according to the invention can be designed in such a way that, parallel to each double-woven cross strip, a single-woven cross-composite strip adjoining it on one side is produced, which closes off the cells at one end, and that the metal fabric strip in each case is cut along a line running near the boundary line between the transverse strips and the composite strips.
  • Each metal fabric plate produced in this way has on one fabric edge a cross-sealing strip which closes the cells and on the opposite fabric edge the two foldable edge strips for exposing the cell openings.
  • Fig. 1 shows a section of the finished fabric
  • FIG. 2 shows an axoniometric representation of a part of a metal fabric plate with unfolded edge strips.
  • Fig. 1 the double-woven web parts are shown by a wide-mesh hatching and the single-woven web parts, ie the fabric composite strips, by a close-mesh hatching.
  • the size ratios of the different web parts are chosen arbitrarily.
  • a metal mesh web 1 with alternately single and double woven fabric strips is first produced, so that parallel, flat cells 3 separated by longitudinal composite strips 2 are formed. With regard to weaving technology, it is irrelevant whether the cells run along or across the longitudinal direction of the fabric web.
  • double-wove te transverse strips 4 are produced, which run transversely "to the longitudinal direction of the cells 3 and in which open the cells with their one ends. 5
  • the mutual distance of twice the transverse strips 4 determines the length of the cells 3.
  • a single-woven cross-bond strip 6 adjoins this on one side, which closes the cells 3 at the other end
  • the longitudinal cuts i.e. the cuts to be made parallel to the longitudinal direction of the cells are carried out along the longitudinal central axis of longitudinal composite strips 2.
  • the cross sections are each made along a line 7, which lies within the double transverse strip 4 and near the boundary line between the transverse strip 4 and the transverse composite strip 6.
  • the transverse composite strip 6, which closes the cells 3 on one side remains on one plate edge, while two edge strips 8 and 9 are formed on the opposite plate edge, which strips can simply be unfolded and pulled apart from one another around the cell openings 10 to expose a plate as a whole and, if necessary, to expand it to such an extent that a mandrel can be inserted mechanically into any cell opening with ease.
  • the initially flat cells 3 are then expanded into tubular cells by driving the spikes through the cells to the other end.
  • Metal fabric plates produced by this process are suitable as carriers for the active mass of alkali accumulators. After the cells 3 have been filled with active material, the edge strips 8 and 9 are folded up again and, for example, to close the cells. connected with a continuous weld.
