Claims
- 1. An apparatus for fabricating a quadrupole shadow mask from a long metal strip having a mulitiplicity of spaced apertures arranged in a plurality of longitudinally extending substantially parallel spaced rows, said apparatus comprising:
- means for storing such a long metal strip and feeding it along a path;
- means for supplying a plurality of strips of insulating material of generally the same width as the spacing between said rows and having on at least one side thereof a conductive layer;
- means for positioning respective insulating strips adjacent said spaces between said rows, with said at least one side being the side remote from said metal strip, and then applying said insulating strips to said metal strip as said metal strip is fed along said path; and
- means for cutting said metal strip with said insulating strips applied thereto into sheets of predetermined length,
- CHARACTERIZED IN THAT said positioning and applying means includes a roller for pressing said insulating strips into engagement with said metal strip, said roller being provided with a plurality of circumferential grooves for guiding said insulating strips into registry with said spaces of said metal strip between said rows.
- 2. The apparatus as claimed in claim 1, wherein said means for supplying includes means for storing a web of said insulating material with said conductive layer and means for cutting said web into said insulating strips.
- 3. The apparatus as claimed in claim 1, including means for heating said metal strip with said insulating strips applied thereon.
- 4. The apparatus as claimed in claim 1, 2 or 3, wherein said roller includes means for slightly varying the distance between each of said grooves.
- 5. The apparatus as claimed in claim 4, wherein said varying means comprises means for heating the roller.
- 6. The apparatus as claimed in claim 5, wherein said roller is formed of aluminum.
- 7. The apparatus as claimed in claim 5, wherein said roller heating means is a heating coil in said roller.
- 8. The apparatus as claimed in claim 3, wherein said strip heating means is a high-frequency furnace.
