Claims

1. A PROCESS FOR TREATING CELLS CONTAINING SPIRALLY WOUND ELECTRODES, HAVING SEPARATOR MATERIAL INTERPOSED BETWEEN ADJACENT ELECTRODES, FOR KEEPING THE SPIRALLY WOUND ELECTRODES OF THE CELL CLOSE TOGETHER AND UNIFORMLY SPACED AT SUBSTANTIALLY THE WIDTH OF SAID SEPARATOR MATERIAL, COMPRISING THE STEPS OF INSRTING SPIRALLY WOUND ELECTRODES INTO A CONTAINER, THE OUTER SPIRES OF SAID ELECTRODES HAVING A TENDENCY OF UNWINDING AFTER INSERTION INTO SAID CONTAINER;

AND THEREAFTER IMPARTING A PERMANENT DEFORMATION TO THE LONGITUDINAL WALL OF SAID CONTAINER;

SAID DEFORMATION BEING OF SUCH A MAGNITUDE AS TO CAUSE THE OUTER SPIRES OF SAID SPIRALLY WOUND ELECTRODES TO RE-ENGAGE EACH OTHER TIGHTLY, BUT NOT TO CAUSE DEFORMATION OF SAID ELECTRODES.
