Abstract
An apparatus for forming a duct includes a bending apparatus and a support apparatus. The bending apparatus includes a table, a cut off beam, and a leaf hinged to a forward edge of the table. The cut off beam is movable toward and away from the table to clamp or release a metal web being fed forward across the table and the leaf. The cut off beam repeatedly clamps the metal web to the table while the leaf pivots toward the cut off beam to form a duct section. The support apparatus includes a cross rod movable along pivoting support arms. As the metal web is bent to form the duct section, the support arms and the cross rod are moved to internally support the duct section.
