Abstract: A pole manufacturing line with a shell forming apparatus in which material blanks (e.g., steel plates, sheets, or the like, other metals, composites, or other material) are cut into one or more shell blanks (e.g., different sizes for different types of poles), and the shell blanks are shaped into shaped shells (e.g., a single shell, half shells, tri-shell, quad shells, or the like). The pole manufacturing line has a shell assembly apparatus in which shells are supplied to a welding apparatus to create longitudinal seam welds in the shaped shells to form the poles, the poles are transported to one or more cells for straightening the pole, trimming the pole length, preparing the pole for components (e.g., base, flanges, supports, or other hardware) and welding the components to the pole.
