ABSTRACT:
A machine for automatically assembling radius elbows and/or O.G. sets, and the method of utilization of the machine. Four edge deformation effecting components, such as Pittsburg rollers or air hammers, are provided for interlocking edge configurations of ducts to be formed, the edge deformation components defining the corners of a vertical quadrate opening. Two of the components are mounted at the same vertical height above a fabrication table for movement relative to each other in a horizontal direction perpendicular to the horizontal direction of feed of duct pieces through the quadrate opening defined by the edge deforming components. The other two edge deformation components are located at substantially the same level as the rollers of the fabrication table, rollers of the fabrication table being disposed on either side of the vertical plane containing the four edge deformation components. The mounts for the edge deformation components are rotatable about vertical axes to accommodate O.G. sets, when being formed, and the maximum horizontal spacing between the components of the respective pairs of edge deformation components is less than the length of the rollers of the fabrication table.
