Abstract
The cathode-inserting machine of the invention has a gun carriage, movable between two stops under the effect of a jack, a retractable sensor and a cathode support. The overall length of the sensor is equal to the travel of the carriage. It is thus enough to measure the distance between the sensor and the cathode when the carriage is at the rear stop and then to move it forward to the front stop in order to position the cathode exactly in its eyelet.
