Definitions

  • the invention relates to a method for forming a support lug of a cathode starting sheet assembly consisting of a starting sheet, a support rod and at least one support lug extending around said support rod and secured to opposite sides of said starting sheet, the method comprising bending a support lug blank around an auxiliary rod having a cross-sectional dimension being smaller than the corresponding dimension of said support rod, and thereafter removing said auxiliary rod and forcing said support rod firmly against the bent end of said support lug.
  • the present invention relates to a method and an apparatus for forminga support lug of a cathode starting sheet assembly consisting of a starting sheet, a support rod and at least one support lug extending around said support rod and secured to opposite sides of said starting sheet.
  • the support rod is advanced in a position closer to the starting sheet blank than its final position, and the support rod being advanced past the lug feed station, the lug blanks are applied behind the support rod and bent around an auxiliary rod inserted between said lug blank and said support rod, and thereafter said auxiliary rod is removed.
  • the lug blanks are applied behind the support rod and bent around an auxiliary rod inserted between said lug blank and said support rod, and thereafter said auxiliary rod is removed.
  • auxiliary rod can be made substantially thinner than the support rod, it is possible to bend the support lugs with a smaller radius than has been possible by the hitherto known methods, and as a result thereof a firm connection between the lugs and the support rod is established upon turning the startingsheet and inserting the support rod into the lugs. This firm connection will reduce the transition resistance.
  • FIG. 1 shows a cathode starting sheet provided with support lugs and a support rod.
  • FIG. 2 shows a perspective view of an apparatus in accordance with the invention, and FIG. 3 illustrates the principle of bending the support lugs according to the method of the invention.

  • FIG. 2 The apparatus for carrying out the method of the invention is shown in FIG. 2.
  • a cathode starting sheet I and a support rod 2 are advanced together along a transport path in such a manner that the distance between the support rod 2 and the starting sheet I is substantially smaller than what it will be in the final electrolyzing bath.
  • an auxiliary rod 4 is inserted between the support rod 2 and the support lug blank feeding station 3, the support lug being bent around said auxiliary rod.
  • the auxiliary rod 4 may be fed into its operative position in various manners depending on. for example, the position of the support lugs.
  • FIG. 2 The preferred manner of feeding the auxiliary rod 4 into its operative position is illustrated in FIG. 2.
  • the auxiliary rod 4 is in an inoperative position below the path of movement of the said parts.
  • the auxiliary rod 4 is raised to the same level the support rod 2, and the support lug blank 6 is fed against the auxiliary rod 4 and bent around it, the free ends of the lug 6 bearing against the starting sheet 1, and the support rod 2 being positioned within the lug 6.
