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.

Method and apparatus for metal positioning and forming

A roll former has a plurality of paired die assemblies spaced apart across a midline of the roll former, and a web of material is fed through the roll former along the midline for operations by the die assemblies. The spacing between each pair of die assemblies is uniformly adjustable by way of mounting the die assemblies on collector plates movable toward and away from each other by linear actuators such as jack screws. Smoothness of movement is enhanced by supporting the collector plates only on the linear actuators. Precision of positioning is enhanced by using jack screws as the linear actuators.

Continuously smoothly adjustable and self-aligning variable width roll forming apparatus

A flange for ductwork is integrally formed at a distal end of a duct surface. A first flange portion is formed perpendicularly outward from the duct surface. A second flange portion is bent at a right angle from the first flange portion and substantially parallel to the duct surface. A third flange portion is bent back to be in substantial touching relationship with the second flange portion and towards the first flange portion. A fourth flange portion is bent at a right angle from the third flange portion to be in substantial touching relationship with the first flange portion. Finally, a fifth flange portion is bent at a right angle from the fourth flange portion to be in substantial touching relationship with the duct surface.
