-34- Abstract Apparatus and Method for Fabricating Wood Trusses An apparatus and method for fabricating wood trusses. The truss members and connector plates are assembled on a conveyor surface, which transports the truss members to a first pressing station where the connector plates are partially embedded into the truss members and then to a second pressing station where camber is imparted to the truss and the connector plates are substantially completely embedded into the truss. The pressing rollers have substantially the same diameter and are sufficiently large to prevent the connector plates from rocking back and forth during the initial stages of the pressing operation. Three elongated guide rails are disposed beneath the conveyor surface to prevent the sagging thereof under the weight of the truss. The two outer guide rails extend all the way through the first pressing station to keep the conveyor surface in proper alignment. Camber is imparted to the truss in the second pressing station by means of two sets of oppositely positioned camber rollers. The first pair of camber rollers is mounted on a pivot arm for contacting the top chord of the truss and the second pair of camber rollers is adjustable by a single adjustment mechanism, laterally with respect to the axis movement of the truss, for contacting the bottom chord of the truss. An adjustable stabilizer bolt contacts the pivot arm to prevent free play therein during the cambering operation. In an alternate embodiment camber is imparted to the truss on the conveyor surface before the connector plates are attached by placing the truss members between a plurality of tooling blocks disposed at predetermined fixed positions on the conveyor surface in accordance with the truss dimensions and desired amount of camber.
