发明名称 I beam nesting and stacking method and apparatus
摘要 I beams are nested and stacked in horizontal bundles preliminary to transporting and storing them by arranging a selected number of I beams in side by side substantially aligned relation to each other. The I beams then are advanced laterally while shifting the leading I beam edgewise until its chords lie in a different plane than do the chords of the immediate following I beam. The two I beams then are telescoped together. The following I beams are similarly nested to provide an I beam assembly which may be tied into a bundle.
