A table (10) is provided to assist in the manufacture of building structures such as walls and the like, where the walls comprise a plurality of studs (60) extending between top and bottom members (14, 16). The table (10) comprises a support surface (12) for supporting the top and bottom members (14, 16) of the wall. In particular, the table (10) is most useful in manufacturing walls of steel studs. The table includes grasping means to grasp the building structure to be able to move the structure along the support surface (12) of the table (10). A computer operated controller controls motors to locate the top and bottom framing members as desired along the table and to locate the top and bottom framing members at desired locations adjacent assembly stations (50, 52). The assembly stations (50, 52) are used to attach a stud (60) to each of the top and bottom members (14, 16). The assembly stations are mounted on tracks and the location of the assembly stations along the track is controlled by a servo motor under control from the controller. The assembly stations may move transverse to the top and bottom framing members. The assembly stations are also movable in a vertical plane so as to be movable below the support plane of the table and to be movable to a plane to form connections. The assembly stations are also pivotable about a vertical axis. By X direction movement of the top and bottom members, Y direction movement of the assembly stations, height adjustable movement of the assembly stations and pivoting of the assembly stations about a vertical axis, the assembly stations can be moved to attach studs facing in either direction or cripple studs to top and bottom members or headers to studs and cripple studs to headers or any combination. Preferably the assembly stations create button type joints by working metal of the top or bottom members and metal of the studs to form buttons. The assembly stations include punches and anvils which may be moved within a stud to form multiple buttons on each flange of a stud simultaneously with internal support for the two anvils. |
