In the formation of a battery, electrodes are connected to connector bars by mounting the electrodes in cassettes on the side of a horizontal rotatable drum. By rotating the drum, the electrodes travel in a vertically oriented, circular travel path between various work stations. Rotary displacement of the electrodes involves forward and rearward movements. All forward movements are of equal distance. All rearward movements are of equal distance. However, the distances of forward movement are different from those of rearward movement. The work stations include an electrode receiving station, a fluxing station, a connector bar casting station, and an electrode removal station. A conveyor travels horizontally through the cylinder, carrying battery containers to receive the electrodes. |

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT The steps of the method depicted in FIG.
1 are as follows.
Along a circle-shaped course 1 are found three work stations, namely a feeding or intake station 2, a fluxing processing station 3, and a casting station 4.
There is also present a station 5 for the removal of finished electrode series from the processing course.
On the circular course have also been posted three points (A,B,C) which follow the movements of the electrode series along the course and whose arrangement corresponds to the position of cassettes in which electrode series have been placed.
We now assume that point A on the circle-shaped course is at the intake station 2.
Electrode series are put down in the cassette which is found at A, whereupon they are made to carry out a movement which in the figure is indicated by -180.
degree.
, that is to say, a half turn to the left.
Point A and the cassette then come to be in the position shown in FIG.
1B.
There is no treatment of the elctrode series at this station, and the next movement is indicated in the figure by +60.
degree.
and involves a turn of one sixth to the right.
The electrode series are then in a position at the pickling station 3 as shown in FIG.
1C.
Here the electrode terminals are treated with flux, whereupon the electrode series are made to carry out a new movement of -180.
degree.
.
They thereupon stop at a station which is indicated by A in FIG.
1D, where no treatment of the electrode series is carried out, but here the flux has occasion to affect the surface of the terminals.
Then follows a new turn of +60.
degree.
, so that the electrode series are placed at the casting station (FIG.
1E).
Here the casting of the connector bars takes place, whereupon a movement of -180.
degree.
is carried out.
The electrode series are then farthest up on the circle-shaped course, where they are removed from the latter.
The course then carries out a new movement of +60.
degree.
, with the result that Point A has again reached its starting position, as is shown in FIG
