Abstract
Disclosed is a machine for the implanting of a cathode in an eyelet of a cathode-ray tube gun. This machine has a gun-supporting device which is movable along the axis of the gun, a cathode-supporting device positioning the cathode along the axis of the gun and a sensor with retractile rod which works together with a first detector, giving the position of the cathode when the rod rests on the grid G1, said sensor being capable of being shifted in a direction perpendicular to the axis of the gun. It further has a gauge rod, with a calibrated length, which rests on the grid G2 and ends at the side opposite to the eyelet, with a second detector recording the position of the gauge rod and a control device determining the shift of the gun-supporting device on the basis of the measurements made by the two detectors.
