Abstract
A truss-fabricating machine comprising a table for supporting a pair of parallel spaced-apart wood chord members, a series of web members spanning the chord members, and connectors having teeth adapted to be pressed into the wood chord members. The machine further comprises apparatus on the top of the table for clamping the chord members in fixed position with respect to the table, including a pair of outside jaws engageable with the outside faces of the chord members, and expansible tubing extending longitudinally of the table for effecting movement of the outside jaws relative to one another transversely of the table to clamp the chord members in fixed position with respect to the table. A press is movable longitudinally with respect to the table for pressing the teeth of the connectors into the chord members when the chord members are clamped in fixed position.
