ABSTRACT:
Cleansing-scavenging means and method are disclosed for removing detritus from the inner surface of the neck of a cathode ray tube during manufacture. The means comprises probe means for insertion into the neck, and scrubbing means extending from the probe means for dislodging detritus. An expansible and contractible scavenging member is attached to a first end of the probe means. The member has a peripheral surface conformable to the inner surface of the neck for exerting, when expanded, outward scavenging pressure against the inner surface of the neck. Handle means are attached to the second end of the probe means for manipulating the probe means, with associated means providing for expanding and contracting the scavenging member. After the detritus is dislodged from the inner surface of the neck by the scrubbing means, and as the probe means is withdrawn from the neck, the scavenging member when expanded scavenges the detritus from the neck.
