摘要：
A method of manufacturing a cathode ray tube, which tube comprises an envelope part (1) having a longitudinal axis (9) and a gun assembly (5) which is assembled on a mounting (15) and has a longitudinal axis (22), in which
a. the envelope part is fixed in a given position in an assembly device (14)
b. the orientation of the gun assembly (5) is adjusted,
c. the gun assembly (5) is fixed in the adjusted orientation,
d. the gun assembly (5) is inserted into the neck (4) of the envelope part (1), the said axes (9, 22) substantially coinciding, and
e. the mounting (15) is sealed to the neck (4) of the envelope part (1).
The orientation of the gun assembly (5) (according to step c) is fixed by means of a clamping device which clamps at least three connection pins (17) which are connected to the gun assembly (5).
