<p>A method for loading and packaging electron tubes comprises (a) providing a base platform having a radial array of nests, each adapted for receiving a tube, (b) positioning the platform with an empty one of the nests in a prescribed position, (c) loading a tube into the nest, (d) rotating the platform about a center to position another empty nest in the prescribed position, (e) loading another tube into the other nest, (f) repeating steps (d) and (e) until all of the nests are filled, (g) providing a cover platform having recesses therein substantially complementary to the nests in the base platform, and (h) positioning the cover platform over the loaded tubes with less than half the height of each tube within one of the recesses, the cover platform being spaced from the base platform by the loaded tubes. The method may further include wrapping plastic sheet material around and overlapping substantial portions of the sides of both the base platform and the cover platform.</p> |
