Definitions

  • each roll PATENTl-Iumm I972 3.686316 FIGJ.
  • Grids are not commonly made from pure lead, and the term lead is used herein to indicate not only the normal lead compounds used to manufacture grids, but also dispersion strengthened lead.
  • the term grid is defined as an open mesh network which for the sake of convenience can be considered to be vertical, and comprises upper, lower and a pair of side frame members, the upper member having a lug integral therewith, and integral ribs interconnecting the frame members.
  • the space referred to will be bounded by the upper frame members of a pair of adjacent impressions, and by the lugs corresponding to these impressions. In either case, this space is usually plane. Assuming that the impressions on the roll each extend axially to the roll, as opposed to the circumferential arrangement described above then the space referred to will be bounded by the lugs of an adjacent pair of grids, the edge of the strip and by the upper frame member or members dependent on their relevant disposition. Other arrangements may be used.
  • the invention which seeks to overcome this problem, consists in one aspect in a roll for use in conjunction with a further roll in forming a battery plate grid from a strip of the grid material, the roll having thereon at least one separate impression of one face of the required grid in in which the space on the roll whose base is defined by the upper frame member and whose height is defined by the lug extending therefrom, is formed with interruptions into which in use the strip from which the grid is being formed will key.
  • interruptions are in the form of continuations of the grid pattern.
  • FIG. 1 illustrates a strip being passed between two rolls
  • FIG. 2 illustrates part of the surface of one of the rolls.
  • a strip 11 typically of dispersion strengthened lead, is passed between a pair of rolls 12 between which pressure is applied to form the required grid.
  • FIG. 2 illustrates part of the surface of one of the rolls 12, which typically has four grid patterns fonned thereon and extending circumferentially round the rolls, two of the patterns being seen in FIG. 2.
  • the dotted lines in FIG. 2 represent patterns which will appear on the other roll.
  • Each grid will'be formed with side frame members 13 and 14, and upper frame members 15 having a lug 16 integral therewith, and a lower frame member 17.
  • the grid forming portions are oppositely directed on the roll, so that a pair of lugs 16 on successive grid patterns are at opposite edges of the roll, but aligned considered in an axial direction, so that between the lugs 16 there is a space 18.
  • Each grid further includes ribs 19 extending parallel with the side frame members, together with diagonal ribs extending in opposite directions on opposite sides of the grid to be formed.
  • the strip of material is not controlled accurately at all times for the reasons explained earlier.
  • the space 18 is interrupted, conveniently as shown by continuations of the diagonal rib patterns, so that control of the strip 1 1 is effected at all times.
