Abstract
A duct making apparatus includes a first station configured to accept a formable sheet material and a second station configured to receive the formable sheet material from the first station. The first station includes a mechanism for forming one of a male lock bend and a female lock seam in a leading edge of the formable sheet material. The second station includes a retractable conveyor. Movement of the sheet material from the first station to the second station defines an axis of travel of the sheet material. The retractable conveyor is selectively movable from a first position in which the retractable conveyor is in close association with the first station, and a second position in which the retractable conveyor is spaced from the first station.
