Abstract
Method for forming a symmetrically bifurcated terminal portion on an existing truss web component having a tubular medial portion and flattened web ends comprises shearing one of the web ends for removing tubing skin from its longitudinal margins, forming two unsupported side walls, and then flattening the side walls. The flattened side walls are wedged apart, separating them relative to one another and forming the symmetrically bifurcated terminal portion. The opposed web end is flattened, forming a comparatively large flattened terminal portion. The apparatus includes a frame having mounted thereon shearing means, splitting means, flattening means, and drive means for accomplishing the foregoing operations.
