<p>The improved machine for the preparation and cutting of kinescopes comprises: a workbench featuring a rotating section pad (4), for holding fast the screen (S) of the kinescope (3), made to move vertically on guides (42); a first work station (2) for preparation in which there are: means for removal (16) of the metal belt from the side (19) of the kinescope; and a second work station (6) for cutting in which there are: two wire elements (30) each mounted on a device with reels (29) for spooling and for maintaining the mechanical tension of the wire; a suction hood (35, 37) that partially covers the machine, featuring also a manually operated suction tube (36); finally, there are in the machine means (20) for incising said side of the kinescope; furthermore, said mobile suction pad (4) is mobile also horizontally in the direction joining the two work station (2, 6), that is running on guides (23) parallel to said direction, while maintaining its grip on said kinescope already prepared in said first work station (2) for cutting. There is also a rotating brush (18) oscillating in the vicinity of the cutting plane (5) for cleansing the surface of said side of residues of glue or powder. Feeler arms (7) are also envisaged for automatically determining the size of the kinescope to be treated and for setting up the subsequent phases of shearing of the electron gun (9), regulating the cutting plane (5) and establishing the heating interval of said elements against said side.</p> |
