ABSTRACT:
An apparatus and method for making welded mesh forms (10) having a stationary center beam (12) and an adjustable center beam (14). Two adjustable side beams (36 and 38) and one adjustable bottom beam and clamp (20) are provided so that any number of circular, arched, and/or elliptical wire mesh forms may be created. Once the desired shape has been properly formed by adjustment, a wire mesh (44) is inserted in between the adjustable clamps contained on the beams. A centering/positioning device (62) then grips the mesh along one free longitudinal edge and holds the wire mesh (44) in place as the clamps are clamped to the wire mesh (44) in clockwise sequence. This clockwise sequence adjusts the prerolled wire mesh (44) and creates a perfectly formed wire mesh (44) in the shape and diameter desired. Once clamped in the desired position, the centering/positioning device (62) is withdrawn and welder (32) and transformer (30) in conjunction with dual weld heads (34) are operated sequentially to automatically weld the entire desired length. Once welding is complete, the welder (32) returns to the operator end (46), the clamps are released and cage ejector (42) is utilized to eject the now welded formed wire mesh (44) from the apparatus (10).
