| 20100083721 | DECOILER FOR WIRE AND ROD - A decoiler for delivery of wire or rod feed stock to a downstream production machine from a pre-formed coil. The decoiler includes an extended length rotatable mandrel adapted to extend along the interior of the coil such that the mandrel supports loops of the coil in hanging and slidable relation along the mandrel. At least a first feed head is disposed adjacent to the proximal end of the mandrel. The first feed head is adapted to feed the wire or rod feed stock from a rear loop of the coil outwardly in a curved path to form a spiral feed loop having a diameter greater than the coil. A variable height guide element is disposed at a position below the first feed head. The variable height guide element engages and follows an interior of the spiral feed loop to change height with a change in diameter of the spiral feed loop and to provide an output signal for speed control of the first feed head to maintain the diameter of the spiral feed loop within predefined limits. | 04-08-2010 |

| 20120055219 | APPARATUS AND METHOD FOR CURVING METAL PANELS - The pressures provided by several wheels or rollers on various members of a metal panel are controlled to produce a curved panel of desired radius with little or no distortion. Predetermined pressures are used to achieve the desired curvature and increased pressures provide smaller radii of curvature. For metal “U” panels pressure is preferably applied on two members. For seamed metal panels pressure is preferably applied on three members. Additional curvature may be obtained by use of a curving bar. Motors drive the wheels, which urge these panel members through the wheels, the wheels having a separation distance less than the original thickness of the metal. This results in the metal of those members being elongated, thereby curving the panel with little or no distortion. In exemplary embodiments curved panels may be formed at a rate of 22-25 feet per minute or at 40-55 feet per minute. | 03-08-2012 |

The sweep unit has a first pair of forming rolls positioned to engage first opposing sides of the structural beam and has a second pair of forming rolls positioned to engage second opposing sides of the structural beam. The sweep unit movably supports the first and second pairs of forming rolls so that any selected one of the forming rolls continuously engages an associated side of the structural beam while an associated one of the forming rolls opposing the selected one forming roll moves downstream and around the selected one forming roll. This provides a very stable beam-bending condition promoting dimensional stability during the sweeping process, and hence dimensional accuracy and repeatability. | 03-24-2011 |

| 20110302982 | Device for Forming Conical Sections - A roll forming machine includes a frame supporting a conical drive roll rotatable on a fixed axis, and a conical pinch roll rotatable and movable transversely and angularly toward and away from the drive roll. Transversely movable and angularly adjustable forming rolls are disposed on opposite sides of the pinch and drive rolls, operable to selectively bend a workpiece frictionally held between the pinch and drive rolls and moved by their counter-rotation. The drive and pinch rolls rotate the workpiece about a transverse axis as they move the workpiece through the machine, enabling a consistent and accurate bending of workpieces to desired conical geometries. The machine can employ elongate drive and pinch rolls with guides to selectively place the workpieces along the rolls, to controllably vary the ratio of small-end to large-end radii in shaped pieces. Alternative versions feature a single forming roll, and rolls that alternatively serve the pinching and forming functions. | 12-15-2011 |
