Methods and apparatus for assembling a truss are described. In one embodiment, the truss table apparatus includes a truss table and a roller assembly. The truss table (24) includes two guides (40A,40B) and a worksurface (44) which supports the truss members as nailing plates are pressed into the truss members. The guides (40A,40B) are coupled to opposing sides (42A,42B) of the truss table and are substantially C-shaped. The roller assembly (28) is movably coupled to the truss table guides (40A,40B) and includes a roller (60) for pressing the nailing plates into the truss members. The roller assembly (28) also includes a plurality of drive wheels (68A,68B,68C,68D) that rest on the truss table guides (40A,40B) to move the roller assembly relative to the truss table (24). The roller assembly (28) further includes a plurality of pressure wheels (70A,70B,70C,70D) rotatably coupled to the truss table to maintain the proper spacing between the roller and the truss table worksurface (44) during pressing of the nailing plates. The apparatus also includes at least one camber tube (32A,32B) and at least one outer rail (36A,36B) for clamping the truss to the worksurface (44) prior to pressing the nailing plates into the truss members. <IMAGE> |
